SAFETY GRATING
Direct Metals — Your Safety Grating Source featuringGrip Strut®
Every year industrial accidents, falls,tripping over debris, slipping on wet or greasy surfaces cost millions of dollars in lost man hours and production. By reducing accidents, insurance costs can frequently be decreased. GRIP STRUT Safety Grating helps reduce accident rates by providing a safer walking-working surface than any other available grating product. Its serrated surface gives maximum slip protection and performance under practically all conditions and in every direction.
The serrated surface is designed in an open diamond pattern. This allows drainage of fluids, mud, chips and otheraccident-causing debris. With 4-1/2" high side channels, GRIP STRUT Safety Grating Walkways meet OSHA requirements for toeboards on elevated structures.
Safer, Serrated SurfaceThe serrated surface grips soles securely in all directions, in practically every place. These non-slip GRIP STRUT Grating surfaces are ideal for inside or outside locations where mud, ice, snow, oil and detergents can create hazardous walking conditions. Openings are small enough to catch most falling tools and other danger-ous objects.
Fast InstallationLight, easy-to-handle planks make installa-tion simpler and quicker. They can be han-dled by one man. Most sections are rapidly bolted, clamped or welded into place,easily field-cut at virtually any angle orfabricated to adapt to field conditions.Several attachment devices permit fasten-ing to most existing surfaces, allowing for fast installation or disassembly.
Serrated Grip Strut GratingOffers excellent slip resistance wherever maximum safety underfoot is essential.Material meets anti-slip values set forth in Federal Specification RR-G-1602A.
Non-serrated Grip Strut GratingFor all-purpose use, where a high degree of slip resistance is required with a
smoother texture and design. Productavailability is subject to extended lead time.
Standard Grip Strut Grating PlanksAvailable in materials and sized to meet most load/span requirements. May be used as is or banded, cut, welded or punched to suit your requirements.
General Load InformationHow to read load tablesTo select size of GRIP STRUT Safety Grating, determine load, clear span, and deflection requirements, and select from the loadtables the appropriate plank to meet your job requirements.
EXAMPLE: Clear span of 4'-0" concen-trated load requirement of 300 lb. at 0.25" max. deflection.
Allowable Uniform Load (U)Values indicated in the rows adjacent to “U” are the lowest of the (1) maximum allowable uniform loads consideringchannel flexure and (2) maximum grating surface flexure.
Deflection Corresponding to “U”Deflection values are indicated below the uniform loads, and are the mid-span side channel deflections for the planks carrying the allowable uniform loads (Figure 3).
Allowable Concentrated Load (C)Values indicated in the rows labeled “C” are the lowest of the (1) maximum allow-able concentrated load considering channel flexure (Figure 2), with both channels effective and (2) the maximum allowable strut load (Cs) for a 1-ft. long sample (Figure 1).
Deflection Corresponding to “C”Deflection values indicated below “C”values in the tables are the mid-span, side channel deflections produced when theallowable concentrated load is placed at mid-span.

BAR GRATING
Glossary TerminologyANCHOR - A device by which grating isattached to its supports. BAND - A flat bar welded to the end of a grating panel or along the line of a cutout, and extending neither above nor below the bearing bars. Load-Carrying Band: A band used in a cutout to transfer the load from unsupported bearing bars to the supported bearing bars. Trim Band: A band which carries no load but is used chiefly to improve appearance. BEARING BARS - Load-carrying bars made from steel strip, slit sheet or rolled or extruded aluminum, and extending in thedirection of the grating span. BEARING BAR CENTERS - The distance center to center of the bearing bars. CARRIERS - Flats or angles, which are welded to the grating panel and nosing of a stair tread, and are bolted to a stair stringer to support the tread. CLEAR OPENING - The distance between faces of bearing bars in a rectangulargrating or between a bent connecting bar and a bearing bar in a riveted grating. CROSS BARS - The connecting bars made from steel strip, slit sheet, rolled bars, or rolled or extruded aluminum, which extend across the bearing bars, usually perpendicular to them. They may be bent into a corrugated or sinuous pattern where they intersect, the bearing bars are welded, forged, or mechanically locked to them. CROSS BAR CENTERS - The distance center to center of the cross bars. CURVED CUT - A cutout following a curved pattern. CUTOUT - An area of grating removed to clear an obstruction or to permit pipes, ducts, columns, etc. to pass through the grating. ELECTRO-FORGED - A process combin-ing hydraulic pressure and heat fusion to forge bearing bars and cross bars into a panel grid. FINISH - The coating, usually paint orgalvanizing, which is applied to the grating. FLUSH TOP GRATING - A type of pressure-locked grating, in which the cross bars and bearing bars are in the same plane relative to the top surface of the grat-ing. GRATING - An open grid assembly of metal bars, in which the bearing bars running in one direction are spaced by rigid attachment to cross bars running perpen-dicular to them, or by bent connecting bars extending between them.
HINGED PANELS - Grating panels which are hinged to their supports or to other grating parts. I-BAR - An extruded aluminum bearing bar having a cross sectional shape resembling the letter “I”. LENGTH - The dimension of a grating panel measured parallel to the bearing bars. Also referred to as span. LOAD-CARRYING BAND - see Band. NOSING - A special L-section member serving as the front or leading edge of a stair tread or of grating at the head of a stair. PRESSURE-LOCKED GRATING - Grating in which the cross bars are mechanically locked to the bearing bars at their intersections by deforming orswaging the metal. RADIALLY CUT GRATING - Rectangular grating which is cut into panels shaped as annular segments, for use in circular or annular areas. RETICULINE BAR - A sinuously bent connecting bar extending between two adjacent bearing bars, alternately contact-ing and being riveted to each. RIVET CENTERS - The distance center to center of rivets along one bearing bar. RIVETED GRATING - Grating composed of straight bearing bars and bent connect-ing bars, which are joined at their contact points by riveting. SERRATED GRATING - Grating which has the top surfaces of the bearing bars, cross bars or both notched. SPAN OF GRATING - The distancebetween points of grating support, or thedirection of the dimension. Also referred to as length. STRAIGHT CUT - That portion of the cut edge or cutout of a grating, which follows a straight line. SWAGING - A method of altering the cross-sectional shape of a metal bar by pressure applied through dies. TOEPLATE - A flat bar attached against the outer edge of a grating or rear edge of a tread, and projecting above the top surface of grating or tread to form a lip or curb. TREAD - A panel of grating having carriers and nosing attached by welding, and de-signed specifically to serve as a stair tread. WELDED GRATING - Grating in which the bearing bars and cross bars are joined at their intersections by a weld. WIDTH - The overall dimension of a grating panel, measured perpendicular to the bear-ing bars and in the same direction as the cross bars.
This catalog uses a form of the NAAMM alpha-numeric designation for bar spacing and manufacturing identification. The first number signifies center-to-center bearing bar spacing in 1/16ths of an inch*. A letter designates method of manufacture. The last number details center-to-center cross bar spacing in whole inches (usually 4" or 2")or rivet spacing (usually 3-1/2", 5" or 7").
Methods of manufacturing and their letter designations used in this catalog include: SG ........ Swaged Rectangular Bar SGF ...... Swaged Flush Top SGI ....... Swaged I-Bar W .......... Welded Steel R .......... Riveted (Steel) AR ........ Riveted (Aluminum)
FOR EXAMPLE:
19-W-4 – Bearing Bars 19/16" (or 1-3/16") c.c. – Welded Steel Construction – Cross Bars 4" c.c. 15-SGI-2 – Bearing Bars 15/16" c.c. – Swaged I-Bar – Cross Bars 2" c.c.
Other Bearing Bar Spacings commonly used throughout the industry are designated thus: 38-W-4 (or 2) Bearing Bars 38/16" c.c. (2-3/8" c.c.) 30-W-4 (or 2) Bearing Bars 30/16" c.c. (1-7/8" c.c.) 22-W-4 (or 2) Bearing Bars 22/16” c.c. (1-3/8” c.c.) 11-SG-4 (or 2) Bearing Bars 11/16" c.c. 7-SG-4 (or 2) Bearing Bars 7/16" c.c. 18-R-7 (or 3-1/2) Bearing Bars 18/16" face-to-face (1-1/8")* 37-R-5 Bearing Bars 37/16" face-to-face (2-5/16")* 12-R-7 (or 3-1/2) Bearing Bars 12/16" face-to-face (3/4")*
*Note: Riveted grating marking indicates space between bearing bars.

ALUMINUM RIVETEDA type of aluminum
grating, which combines
straight bearing bars and bent
connectingbars riveted together at their contact points. Riveted grating, although being the oldest style of industrial footwalk, is still the choice of many engineers due to its reliability and durability. All popular sizes and spacings of riveted grating are available.
ALUMINUM PLANKA type of
extruded grat-ing, which is
available In 6" wide sections, and either
plain sided or Interlocking. Plank can be
provided in sections up to 26'0" in length, or fabricated per plans and specs. Plank grating is available unpunched as an eco-nomical and structurally superior substitute for aluminum checkerplate, or with a vari-ety of punch/patterns.
Aluminum ProductsALUMINUM
FLUSH TOP A type of pressure
locked grating in which the cross
bars are in the same plane rela-tive to the top surface
of the grating. Bearing bar sizes range from 1" x 1/8" through 2-1/2" x 3/16" in 1/4" increments. Bearing bar spacing of 13/16", 15/16", 11/16" and 7/16" c.c. and cross bar spacing of 4" or 2" are available. Where skid resistance is desired, a serrated surface can be provided.
ALUMINUM RECTANGULAR
BARA type of
pressure lockedgrating madeby
permanentlyattaching cross bars to bearing bars through a pressure applied swaging pro-cess. Bearing bar sizes range from1" x 1/8" through 2-1/2" x 3/16" in 1/4"increments. Bearing bar spacing of 13/16", 15/16", 11/16" and 7/16" c.c., with cross bar spacing of 4" or 2" are available. Where skid resistance is desired, aserrated surface can be provided.
ALUMINUM I-BARA type of pressure
locked grating, which utilizes
an “I” shaped bearing bar ranging in size from 1" x 1/4" through
2-1/2" x1/4" in 1/4" increments. Bearing bar spacing of 13/16" and 15/16" c.c. and cross bar spacings of 4" or 2" are available. The I-Bar design takes advantage of the aluminum extru-sion process by placing the metal where it is most effective, at the outermost fiber, while reducing the thickness of the neutral axis web. This design consideration allows the same load carrying capacity at less weight per square foot than rectangular bar, therefore resulting in a cost savings.
PRESSURE LOCKINGThe most common method of manufactur-ing aluminum bar grating is through a process known as pressure locking.
Pressure locked grating as de-fined by the NAAMM
Metal Bar Grat-ing Manual is “Grating in which the cross bars aremechanically locked to
the bearing bars at their intersections by deforming or swaging the metal.” Direct Metals provides a permanently attached pressure locked joint, which will give long lasting life under normal service conditions.
Aluminum Plank Grating
GRATING TYPES AVAILABLE IN ALUMINUM
Where economy is a major consideration, the I-Bar SGI Series offers a popular andreasonably priced alternative to rect-angular bar grating. Extruded I-Bar sections have the same load carrying capacity, with less weight per square foot than rectangular bars. The stri-ated top and bottom flanges provide a “built-in” skid resistance feature without the added cost of serrating.

Aluminum Plank Section AvailabilityAluminum Plank is structurally sound and cosmetically attractive. Plank grating is non-sparking, non-magnetic, non-skid and relatively maintenance free. It is durable, corrosion resistant, and possesses a high strength-to-weight ratio. The surface can be provided unpunched or with a variety of punch/patterns for the passage of air, light, heat or moisture. The interconnecting webs offer a flush top walking surface. Aluminum plank grating has found application in sew-age and waste water treatment plants, as well as in the marine refrigerator (reefer), freezers and cargo-hold flooring market.Aluminum plank grating is available in five cross-sectional designs: Heavy Duty (plain sides), Heavy Duty (interlocking sides), Light Series (plain sides), Reefer (plain sides) and Reefer (interlocking sides).
The Heavy Duty sections are used primarily in water and waste treatment and the marine markets, while the Light Series and Reefer sections are exclusively in the marine refrigerator applications.Interlocking Heavy Duty, Reefer sections and edge sections are available in 1" deep grating only.
Plank Punch / Pattern AvailabilityAluminum plank grating is available unpunched or with a variety of punch/patterns as shown below. Rectangular or square punched holes are most commonly used for water and waste treatment plants, and in marine applications, while the round holes find applications primarily in the marine market. The surface of plank grating can be specified as plain, or with one of two styles of upsets designed to promote a slip resistant walkway, especially in the presence of moisture, oil or other spilled substances.

Light Duty Welded Steel (W Series)
GRATING TYPES - LIGHT DUTY WELDED STEEL W SERIES
HOW TO SPECIFY: 1. Grating: Light Duty Welded Steel W Series. 2. Bearing Bars: Rectangular Bar on 1-3/16" centers maximum. (Note: Other spacings may be specified at the discretion of the architect/ engineer.) 3. Cross Bars: Electroforge welded at right angles to bearing bars at 4" centers maximum. (Note: 2" cross bar centers may be specified at the discretion of the architect/engineer.) 4. Surface: Plain. (Note: A serrated surface may be specified for maximum skid resistance.) 5. Loading: Grating to carry a pedestrian loading equal to 100# per square foot over the required clear span with deflection not to exceed 1/4". (Note: Alternate loading requirements may be specified at the discretion of the architect/engineer.) 6. Finish: Galvanized or manufacturer’s standard black paint at the discretion of the architect/engineer. 7. Fabrication and Tolerances: In accordance with the NAAMM Metal Bar Grating Manual.
For those areas requiring the corrosion resistance of stainless steel, Direct Metals stocks 1" x 3/16", 1-1/4" x 3/16" and1-1/2" x 3/16" 19-W-4 Type 304 stainless steel electroforge welded grating. Since the welding process discolors the stain-less surface, this grating is best suited for industrial applications only and should not be specified where cosmetic appearance is important.

Clear Span
*Based on 10.105 bars/ft. of grating width. Bearing bars 1-3/16" c.c. Add .6 lbs./sq. ft. for 19-SGCS-2. Note: Grating for spans to the left of the heavy line have a deflection less than 1/4" for uniform loads of 100 lbs./sq. ft. This is the maximum deflection to afford pedestrian comfort, and can be exceeded for other types of load at the discretion of the engineer. The actual “Ped (pedestrian) Span” under this condition is shown above for each size of grating. When serrated grating is specified, the depth of grating required for a specific load will be 1/4" greater than that shown in these tables. 3/4" x 3/16" serrated grating is NOT available.

FIBERGLASS
Fiberglass Grating ProductsMOLDED FIBERGLASS GRATINGMolded fiberglass grating is a fiberglass-reinforced plastic (FRP) that combines fiberglass rovings with thermosetting resins to form a strong, one-piece molded panel. A 65%/35% resin to glass weight ratioprovides high corrosion resistance. Meniscus surfaces, or applied grit surfaces provide slip resistance when compared to other flooring prod-ucts. This product is better suited for corrosive environments.
PULTRUDED FIBERGLASS GRATINGPultruded fiberglass grating is made using premium gradeisophthalic polyester, vinyl ester or phenolic resin systems with asynthetic surfacing veil, making it corrosion resistant, lightweight, and durable. Pultruded fiberglass has a grit surface for safety, and a greater strength to weight ratio than molded fiberglass grating. A 35%/65% resin to glass ratio provides greater strength and lesscorrosion resistance than molded fiberglass. This product is better suited for longer spans.
FIBERGLASS COVERED GRATINGOur fiberglass covered grating is a long-lasting, molded fiberglass floor product that combines smooth, gritted or checker plate and molded grating manufactured with any of our resin systems. It is the ideal choice when a 100% covered flooring surface is needed. Ourfiberglass covered grating is often used in loading and storage areas with high foot and cart traffic, where a strong, level surface is ideal. It offers approximately 50% higher stiffness values than that of open mesh grating, and its standard grit-top cover assures secure footing.
BULLET RESISTANT FIBERGLASS PLATEOur bullet resistant fiberglass plate offers superior ballistic resistance at a weight less than 25% that of a comparable steel panel. Now avail-able for commercial security applications for your business, home or governmental facility, these fiberglass panels offer ballistic resistant security with the additional performance advantages of durability, cor-rosion resistance, electrical non-conductivity, low thermalconductivity and light weight.
HEAVY DUTY FIBERGLASS GRATINGOur heavy duty fiberglass grating is available in both molded and pultruded grating systems. Both are designed to carry forklift and trac-tor-trailer loads that traditional molded and pultruded FRPgrating products are not designed to support. Heavy duty fiberglass grating provides greater durability for higher volume traffic areas as well. Additionally, heavy duty fiberglass grating can be used to free span longer distances than traditional fiberglass grating
CUSTOM MATCHED COLORS AVAILABLEWill match to any RAL color.
FIBERGLASS STAIR TREADS & STAIR TREADCOVERSLightweight and easy to install, fiberglass stair treads are available in both molded and pultruded types, to match the fiberglass floorgrating platforms. Fiberglass stair tread covers are made from a molded glass and resin system that is corrosion and impact resistant, fire retardant, and non-conductive. They provide a cost effective,slip-resistant, protective surface for concrete, metal and wood steps.
FIBERGLASS GRATING HANDRAILS AND LADDERSFiberglass handrail systems are fabricated from pultruded fiberglass components and molded thermoplastic connectors. Our modular fiber-glass grating handrail systems are available in 2" square or2" round configurations that are easy to grip, making them ideal for any high traffic area. Our fiberglass ladders and cages can beinstalled in a variety of applications, from sumps to tanks, buildings, piers, portable equipment, etc., providing years of strength anddependability.
FIBERGLASS ATTACHMENTS AND CLIPSOur fiberglass grating attachments and clips are specially designed to secure fiberglass grating or plates to the supporting structures.Additionally, they are used to fasten together adjacent gratingpanels, which minimizes load-induced differential deflection. Allfiberglass attachments and clips are made of Type 316 stainless steel, and are available in 1", 1-1/2" and 2" sizes.
FIBERGLASS PLATESFiberglass plates feature a non-conductive surface that makes them an economical and safe solution to walking surfaces. In caustic and/or acidic conditions, fiberglass plates provide a level of corrosionresistance that is unequaled and more cost effective than stainless steel. Fiberglass plate is available with a non-grit surface, or with a grit surface where anti-slip traction is needed.
FIBERGLASS STRUCTURAL SHAPESOur fiberglass structural shapes and pultruded fiberglass profiles are made from a combination of fiberglass and thermosetting resinsystems. All shapes are lightweight, impact resistant, lowmaintenance, non-magnetic, low conductive, and have dimensional stability, making them easy to install and ideal for severalapplications. Custom shapes are available upon request.

Pultruded Grating
All of our pultruded gratings are manufac-tured with a high percentage of glasswithin the laminate, providing durability, extremely high unidirectional strength, and stiffness. Due to its exceptional stiffness, it can be used with confidence in applica-tions where wide support spans arerequired. For most applications where it is used to replace corroding steel grating, our pultruded grating rarely requiresadditional support.
Designed specifically for pedestrian walk-ways, our pedestrian floor grating is ideal
for any application where a corrosion-re-sistant, durable, lightweight surfacematerial is required. Our pedestrian grating is available in 1" and 1-1/2" depths and in several configurations and panel sizes. 1" deep pedestrian grating is designedfor access areas and walkways where pedestrian traffic is the heaviest load. 1-1/2" pedestrian grating is approximately three times stiffer than the 1" deep version and is used for applications where wider spans (up to 72") or lower deflectioncriteria are required.
To form a pultruded element, continuous fiber rovings and mat are mechanically drawn through a resin bath and shaped through a series of forming guides, then pulled through a heated die.
LIGHTWEIGHT YET DURABLE - less than one-half the weight of steel grating,allowing easy removal for access below floor level and installation with no heavy equipment and less manpower required.
ADDED SAFETY - durable grit surface,permanently bonded, and baked to thegrating surface, for a safe, slip-resistant walkway.
FIRE RETARDANT - flame spread rating of 25 or less, according to ASTM E-84; meets the self-extinguishing requirements of ASTM D-635.
MAINTENANCE FREE - corrosion resis-tant and requires no scraping, sandblast-ing or painting; install it and forget it.
UV PROTECTION - UV inhibitors included in the resin formulation, along with a sur-facing veil and grit top surface for optimum protection from the effects of weathering.
EASILY FABRICATED - no need for lift-ing equipment or expensive tools; can beeasily carried by two workers and cut using standard circular or saber sawsfitted with carbide blades.
ELECTRICALLY AND THERMALLY NON-CONDUCTIVE - providing additionalworker safety.
ELECTRONICALLY TRANSPARENT - does not affect electromagnetic or radio wave frequencies.
Combining corrosion resistance, long life, and a maintenance-free design, our pul-truded grating is superior to conventional metals. This advanced grating is also light-weight and easy to fabricate, making it less expensive to install. In fact, the savings on labor and equipment often make the total installed cost of our pultruded gratingcomparable to that of steel. Combining it’s low cost of installation with main-tenance-free long-life, it is manufactured with a recessed tie bar configuration and an inherent resiliency, which reduces back and leg strain and contributes toergonomics and worker productivity.
FEATURES AND BENEFITS
CORROSION RESISTANCE - based on the use of premium grade, isophthalic polyester or vinyl ester resin systems and a synthetic surfacing veil.

IMPORTANT FEATURES OF STAIR TREADS & STAIR TREAD COVERS
• Corrosion resistant • Slip resistant • High impact resistant • Durable • Low maintenance • Fire retardant • Lightweight • Easy to install • Non-conductive
Safety and durability are just two of many out-standing features that make fiberglass stair treads and stair tread covers preferred compo-nents for stairs and landings. Maximum pedes-trian safety is provided by the anti-slip walking surface. Fiberglass stair nosings form a highly visible and durable edge at the primary point of contact on stairs and landings. Fiberglass stair treads and stair tread covers provide a cost-effective, slip-resistant protective surface for concrete, metal, and wood steps.
Stair tread covers are made from a molded polyester mat that is corrosion and impact resistant, fire retardant, and non-conductive. Stair treads come in 8-, 9-, 10-, 11- and 12-inch depths, with a standard thickness of 1/8 inch with 1/4-inch thick covers available for heavy duty applications. Standard 12-foot stair treads are easily cut to size during installation, or are available precut to custom lengths.
Fiberglass stair tread covers have a durable aluminum oxide grit surface, which increases the safety of stairways, and protects exposed edges that are prone to chipping and cracking.
Lightweight and easy to install, industrial grade fiberglass stair treads are available in 1-inch and 1-1/2-inch deep “I” bar struc-tural profiles with a variable open area of 40%, 50% or 60%. We also carry 2-inch deep “T” bar structural profiles with 33% or 50% open area. Stair tread covers are black or dark gray with highly visible yellow nosings, and are available in 9- and 10-inch widths by 12-foot lengths.

EXPANDED METAL
REGULAR EXPANDED METAL
FLATTENED EXPANDED METAL SHEARING
Regular Expanded Metal is a finished product, as it comes from the press after having been die cut and expanded. Illustration shows that the strands and bonds form a sharp angle to the original plane of the solid sheet.
Flattened Expanded Metal is regularexpanded metal, which has been cold rolled, leaving a flat, smooth surface.
SIDE SHEARINGThe process of cutting a piece ofexpanded metal parallel to the longdimension of the diamond.
Random Side Shearing - Side shearing is a cut made parallel to the LWD dimension of the sheet, which usually leaves open diamonds. Flat expanded metal SWD shearing tolerance is plus or minus 1/8" when both sides are sheared.
Bond Side Shearing - This cut is made along the length of the sheet on the center line of the bond over the specified width. In most cases, it is not practical to attempt to Bond Side Shear either regular or flattened expanded metalbecause of camber.
END SHEARINGThe process of cutting a piece of expanded metal parallel to the short way of the diamond.
End Random Shearing - The process of shearing a piece of expanded metal to a specified length (LWD). This cut normally leaves open diamonds at both ends, but accomplishes close tolerance (plus or minus 1/8") when both ends of flatexpanded metal are sheared.
End Bond Shearing - The process of shearing a piece of expanded metal to a specified length (LWD). A plus or minus 1/8" tolerance applies when both ends of flat expanded metal are sheared. One end is cut on the Bond parallel to the SWD, the other end usually has open diamonds.NOTE: When end bond shearing isrequested for both ends of flat expanded metal, the sheet is sheared at the center line of the bond over the specified length. A tolerance minus 0 plus 1/2" diamondapplies. It is possible to end bond shear, but extraordinary care must be exercised to maintain the squareness of the sheet.
SQUARENESSWhen all four sides of a sheet of expanded metal are sheared, the maximum toler-ance will be plus or minus 1/16" per foot of width.

TerminologyCALENDERING - A rolling operation which flattens the knuckles of wire cloth, giving it a smoother surface.
CRIMP - Undulations in warp and fill wires, which hold each other in place.
FILL WIRE - AKA shute wire, wirerunning across the width of the cloth.
FILTER CLOTH - Cloth used for flattening or straining (primarily plain and twilled dutch wire cloth and certain specifications of square mesh and off-count standard wire cloth).
HARDWARE CLOTH - Plain weave square mesh cloth of relatively light wire galvanized after weaving (usually between 2 to 8 openings per lineal inch).
MARKET GRADE - Applies to wire cloth specifications, most commonly used for general work. Market grade cloth is made of one size wire for each size closed mesh.
MESH - Number of openings per lineal inch, measured from center of wire tocenter of wire.
MICRON - 1/1000 millimeter, 0.00003937 inch. The unit of measure for particle retention of filter media.
OIL TEMPERED WIRE - High carbon steel wire that is heat resistant to produce good strength and abrasion resistance.
OPENING - Dimension between parallel adjacent wires. RECTANGULAR MESH - Wire cloth with different warp and fill wire mesh counts, which results in rectangular openings. The most common have a higher warp mesh than filter mesh. Advantages are increased open area, and reduced cost. SELVAGE - The finished edges of wire cloth running the length of the roll, which are produced by the weaving operation.
SPACE CLOTH - Wire cloth specified by the opening size, rather than by the mesh count.
SQUARE MESH - Mesh with equal spac-ing of warp and shute to give squareopenings.
WARP WIRE - Foundation wires running parallel to the length of the cloth.
WEAVES - Pattern in which wires areinterwoven.
WIRE DIAMETER OR GAUGE - Diameter of wire used in weaving cloth.
2 MESH WIRE CLOTH(count from center to center of wires)
1/2 INCH OPENING WIRE CLOTH(clear space between wires)
PLAIN WEAVEWires are crimped in a zig-zag fashion, with wires intersecting at every available crimp or pocket.
INTERCRIMPWires are crimped in a zig-zag fashion, with intersections at every 3rd, 5th or 7th, etc., crimp or pocket.
LOCK CRIMPDistinct crimp or pocket at wire intersec-tion, with straight connecting sections of wire.
