Corrosion classes

4

The life expectancy of a cable support system is dependent onthe environment in which it is placed. Therefore, it is important toestablish the corrosive properties of an environment to ensure that the right treatment and the right material are chosen.To achieve this, several corrosion classes have been drawn up inaccordance with BSK99.

The table below shows various corrosion classes. As a guide,we have included the surface treatment recommended by Wibefor the different classes.On the next page, we briefly outline the various surface treatments and materials.

As regards environmental corrosion, a steel design component can usually be assigned to one of the corrosion classes (C1-C5-M)as shown in table 1:23a. Reference values for the average level of corrosion in steel and zinc are given in table 1:23c.The corrosion classes comply with those stipulated in SS-EN ISO 12944-2.

Table 1:23aCorrosion classes as stipulated by SS-EN ISO 12944-2 with atmospheric corrosion levels and examples of the environment in whichthey are most suitable for use.

Electro-galvanizedProducts are manufactured in accordance with DIN 50961/ISO 2081. Such products are intended for use only in warm, dry areas withnegligible pollutant levels.

Pre-galvanizedProducts are manufactured from Z 275 pre-galvanized sheet steelin accordance with SS-EN 10327:2004. Surface sections created during cutting and drilling will, under normal conditions, repair them-selves, providing the plant with superb anti-corrosion protection.

Hot dip galvanizedWibe has one of the most modern hot dip galvanization plants in the Nordic countries. The hot dip process is continuous, guaranteeing a high and even quality.Once manufactured products are hot dip galvanized in accordance with EN-ISO 1461:2009 whilst nuts and bolts are hot dip galvanized in accordance with SS-EN ISO 10684:2004. This form of galvaniza-tion affords very good value-for-money anti-corrosion protection inatmospheres with a pH value of between 6 and 13.However, in acidic environments where pH levels fall below 6 and in alkaline environments where the pH value exceeds 13, the protective zinc layer breaks down relatively quickly.

Zinkpox®The Zinkpox® method involves applying a homogenous polyester coating to the zinc layer.Besides resisting light-initiated degeneration and weathering, this powder coating has excellent mechanical properties as regardsimpact resistance and adhesion.It is also resistant to most chemicals.Compared to hot dip galvanizing, applying a polyester coating to the zinc layer more than doubles the service life of treated components. The zinc layer prevents the development of filiform corrosion.This might otherwise degrade the coating.Consequently, the polyester coating is subject only to atmospheric attack and thus protects the zinc layer.

The certified coating plant that treats our components uses a modern and environment-friendly process. Before powder coating, the galva-nized components undergo meticulous pre-treatment.This ensures superb adhesion.In addition to extremely good corrosion protection, the Zinkpox® method also offers a choice of colours. Powder coating is a veryenvironment-friendly way of achieving a coloured surface. Because the coating contains no solvents, it has largely replaced solvent-based liquid coatings.Where installations are visible, cable ladders, cable trays and fittings can be finished in a coating that matches the surrounding décor.

Thermoplastic coatingAn option for corrosive environments. Thermoplastic coating is a thermal process in which a plastic powder is melted to give thecomponent (most usually metal) a special coat.Thermoplastics are predominantly employed in aggressive environ-ments up to and including corrosion class C5-M (ISO 12944-6) where they provide hardwearing, long-lasting and environment-friendly protection against, amongst other things, corrosion.Because the coating process is thermal with no solvents, it hasminimal impact on the environment. Thermoplastic coatings meet the requirements of the mostaggressive environments, e.g. wet, humid environments and those with large temperature variations and concentrations of chemicals. Besides durability, the coatings also have high impact resistance.As the coating provides complete cover, is pore-free and strong, it is also hygienic and dirt repellent.

Stainless steelProducts manufactured in accordance with SS 2333/AISI 304 orSS 2348/AISI 316L are designed for use in highly aggressive environments, either indoors or outdoors, on industrial sites where there are high levels of potent airborne pollution such as in certain chemical industries, cellulose-related industries, refineries or artifi-cial fertiliser factories, high humidity tunnels, etc.Stainless steel products are also ideal for use in environmentswhere special hygiene requirements are in force, such as dairies,abattoirs, other food industries and pharmaceutical factories.

Stainless steel AISI 304 or AISI 316L?The deciding factor in choosing between stainless steel AISI 304or AISI 316L is the aggressiveness of the environment in which it is to be used, and for this atmospheric chlorine content plays a signifi-cant role. Environments with a high chlorine content - coastal areas being a prime example - are aggressive and usually require the use of AISI 316L materials.When assessing the needs of factories, consideration should begiven to the materials previously used to suspend equipment suchas pipe tubing, and from this determine whether stainless steel AISI 304 or AISI 316L material is required.

Factors to consider when installing Stainless Steel CableLadder Systems1. Transport/handlingMake sure that no iron objects come into contact with the stainless steel products.2. StoringNever store stainless steel products near where iron products are machined, for example, close to cuttingand grinding operations.3. WeldingWelding during installation should be avoided where possible. If welding must be performed, make sure that only methods suitablefor stainless steel are used.4. ToolsWhen cutting or grinding, always use cutting wheels and grinding tools which are free from iron. Do not use tools that have beenpreviously used for cutting or grinding products containing iron. When drilling, use an HSS-drill. To maximize the useful life of thedrill, employ a cooling fluid during drilling.When installing, conventional assembly tools can be used. However, when using a nut tightener, ensure that the thread is first lubricated to prevent jamming.Never mix untreated or galvanized products with stainless steel!5. MeasuresIf a blue annealing appears when cutting, grinding or drilling, remove it with pickling paste, making sure that the paste is then carefully washed away with water.If selective corrosion appears it can be removed by:a) Washing away with water (high pressure if possible).b) Polishing with a cleaning cloth or a fine emery paper (wet or dry) and washing with water.c) Grinding with a fine-grained wheel and washing with water.d) Pickling with pickling paste, making sure that the pickling pasteis then carefully washed away with water.6. When using pickling paste or similar productsAlways study the safety code for the product prior to use.

Installation of cables on LadderThe installation of cables on ladders comes within the IEE Regulations for Electrical Installations.Because Wibe ladder has rungs which occupy less than 10% of the plan area under the cables, the installation is defined as cablesin "free air" (Method 12 of Table 9A of the IEE Regulations).Cable spaces in accordance with Method 12 do not require any de-rating factor for installation. Cables touching must be de-rated in accordance with table 9B.

Extract from table 9B

Installation of Cable LadderThe installation of cable ladder is a structural steel support design question which does not have any regulations. Full design data isgiven in the Wibe data sheets in this catalogue showing all maxi-mum and recommended loadings.Any support system which is supported at intervals and loaded will deflect between the support intervals. Graphs are given in this cata-logue to show the deflection against loading for various supportdistances.

Extract from table 9ASheathed single-core cables in free air (any supporting metalwork under the cables occupying less than 10% of the plan area):

1. Two or three cables vertically one above the other, distance between cables equal to the overall cable diameter (De): Distance from the wall not less than 0.5 De.

2. Two or three cables horizontally, with spacings as above.3. Three cables in trefail, distance between wall and surface of

nearest cable 0.5 De or nearest cables 0.75 De.

Installation instructionsInstallationThe ladders and trays shall be installed in such a way that, as often as possible the cables can be laid directly in place rather than being pulled through.Ladders and trays for current carrying cables along the ceiling shall be installed in such a way that the distance from the top of the ladder or tray to the ceiling shall not be less than 300 mm.The free vertical distance between parallel ladders and trays shall be at least 200 mm.Ladders and trays near walls shall be installed with a minimum free distance of 50 mm to the wall, so that cables can pass between the ladders and the wall.Ladders and trays along partition walls shall be installed with mini-mum free distance of 100 mm to the wall.Sharp edges and screw ends on ladders or trays should be removed before the cables can be installed.Expansion bolts for the installation of brackets/fixings shall be installed with such a distance between them, that the designated load for ladders and trays will not be exceeded. When selecting the distance between cantilever arms or brackets/fixings, the bearing strength and designated load of the ladders and trays must be taken into consideration.

Reinforced heavy duty cable laddersLadders shall be designed for a uniform load of at least 600 N per 1000 mm ladder length with a distance of 6000 mm between brackets/fixings. They shall also be able to carry an occasional point load as to the heavy duty ladders.
