Product Information

Galvanised Steel to EN 10147 S320GD + Z275 in a range of gauges

including 0.75mm, 0.88mm, 1.00mm, 1.13mm, 1.25mm and 1.50mm.

Aluminium 3004 grade in 1.25mm and 1.5mm thicknesses.

Standard internal finish off-white 15-micron RAL 9002 polyester,

25-micron polyester available for external applications or a more

aggressive internal atmosphere. Other colours such as RAL 9010

bright white or plain galvanised are available to order.

The nominal gauge of the steel material is measured over the zinc,

which is specified by weight (275g/m2) and taken to be 0.04mm in

thickness for structural calculation purposes. e.g. 1.25mm gauge is

taken to be 1.21mm steel thickness.

Bundle weights are 3t as standard with 1t available to order.

Perforated deck profiles

VTA deck profiles have web perforations in a choice of 4 patterns,

full web depth or half web depth.

The patterns available are shown in the table. The % open area

refers to the actual area of web perforated and when expressed

by flat area or developed area, will vary per profile.

Contact SpeedDeck technical to select the best pattern for your needs.

System Design and Performance

Structural design considerations

1. When using structural decks in conjunction with

SpeedDeck or SpeedZip a continuous 30mm deep

1.5mm galvanised steel top hat spacer orientated

at 90º to the deck profile must be used in addition

to the normal IsoBar spacer. This item is to ensure

that the roof loads are distributed evenly over the

deck profile and not concentrated in occasional

ribs. The top hat section follows the curve of the

roof, and as with the SpeedDeck sheet, the top

hat needs to be pre-curved if the radius is below

55-60m. Consult SpeedDeck for advice where

aluminium decks are used. If short tophat sections

are used in preference to continuous sections,

contact SpeedDeck for revised load capacities for

the particular application.

2. Main fixings are normally 5.5mm diameter

self drilling and tapping screws with washers,

Hilti DX76 shot fired fasteners, or self tapping

screws when the thickness of the steel support

is greater than 12mm. Powder actuated

fasteners can be faster and more economical

for steelwork over 6mm thick. With aluminium

decks use stainless steel fasteners. Powder

actuated fasteners avoid swarf between the

deck and structure.

3. Stitching fasteners are either self drilling and

tapping screws or pop-rivets. If the deck is to

provide diaphragm action, the stitchers must

be 5.5mm diameter steel screws. Note that

designers often prefer rivets because they are

less obtrusive, but note the needs for stress

skin design.

4. During the design stage, in addition to checking

the load tables, it is important to check the

design capacity of the fixings for pull out, pull

over and tensile failure. It is feasible that the

standard fixing recommendations may not be

sufficient in some circumstances.

5. Structural decks are commonly used on curved

roofs with the curve being formed across the

width of the profile. It should be noted however

that decks curved along their length are not

available. Due to the depth and stiffness of the

profiles a natural curve cannot be achieved

unless the radius is well in excess of 100m for

most of the profiles.

6. Decks will offer lateral restraint to the

supporting structure. They can also act as the

stressed skin in a diaphragm roof design, where

a number of additional fixings to the norm

may be required. A requirement for diaphragm

action should be flagged up at the early design

stage. Calculations for diaphragm action can be

provided but at an additional cost.

7. The deck is a structural member and therefore

it is imperative that any openings are limited in

size in order to maintain the section properties.

Openings in decks should be limited in width

to one pitch of the profile and local trimming

may be required to stiffen cut edges. Any

penetrations larger than these will require

a trimming framework taken from the main

support structure.

8. Cantilevers should be less than 25% of the

adjacent span and include an end stiffener

across the end of the profile.

Acoustics

Where the acoustic performance of the roof

structure is of importance, SpeedDeck can

provide the solution.

Sound insulation - Due to their nature, with

several separate layers, built up systems offer

good sound insulation when compared with

other types of metal roofing systems such as

composites, without any special steps being

taken. To give improved resistance to the

passage of noise from outside to in, or vice versa,

SpeedDeck Structural Decks can be specified

using thicker material than is required solely for

structural reasons. This increases the stiffness

of the profile and adds mass to the system, two

positive factors towards increasing the sound

reduction capability.

SpeedDeck VT35 1.25mm deck can be used as a

shallow liner in SpeedDeck acoustic constructions.

Combined with 200mm 23kg/m3 RockWool

insulation and 0.7mm steel SpeedDeck, the

constructions have tested SRI of 49dB, 47dB with

0.9mm aluminium. (Construction type M, SRL-

C/02/5L/ 0520/1 see graph)

Acoustic test results for this and numerous other

systems are available from SpeedDeck Building

Systems Limited upon request.

Sound absorption - The absorption performance

can be improved by perforating the structural deck

and introducing 30mm of acoustic insulation below

the vapour control layer specifically to absorb

the sound passing through the holes. Refer to the

diagram below from SRL report C/04/5L/0905/1

for typical sound absorption coefficients.

This gives a more comfortable environment

in buildings such as sports halls, school halls

and auditoria.

Standard bundle weights are up to three tonnes.

Note: one tonne or two tonne bundle weights can be

supplied but can incur an additional transport cost.

Bundles are supplied with the profiles upside down,

with the white or soffit face upwards, to reduce the

risk of scratching during handling.

Decks up to 6m in length can be off-loaded by forklift.

Bundle lengths up to 10m can be craned off using

slings only, lengths greater than this will require a

beam and slings.

Where spanning across the fall, rainwater during

construction may collect in the pans of the deck.

Every effort should be made to clear any water

and dry the deck prior to the remainder of the roof

system being installed.

Both perforated profiles and solid deck profiles

always require a vapour control layer. This will form

the vcl and air barrier and must be robustly sealed at

laps, perimeters and at penetrations. The vcl is the

only barrier and must be sound and well sealed.

Special attention is needed over partition walls

in terms of sound transmission. At compartment

walls, give consideration to the need for profile

filler blocks within the construction for acoustic

and fire purposes.

1. The loads shown in the tables are safe working loads, with a factor of safety of 1.5 (an average of 1.6 for live loads and 1.4 for dead) for the imposed loads. The factor for the wind uplift loads is 1.4. 2. To qualify as a double span the smaller span must be at least 85% of the larger. 3. No allowance need be taken for the self weight of the deck, this is catered for within the tables. 4. The imposed loads and the web crushing capacities shown have been calculated using a support width of 100mm. Other widths may have an effect on the load capacity. 5. Deflection under imposed loads is limited to 1/250 of the span. If other coefficients are required please contact the Technical Department. 6. These tables are intended for an assessment of the load capacity, more detailed calculations are available. 7. The tables assume uniform loads.
