SLE Cladding - Cladding (Plastisol)

Plastisol coated steel roofing & cladding Sheets are a top performing coated steel sheet and ideally suited to UK condition, a 200 microns (nominal thickness) high performance Plastisol coating on a hot-dip zinc coated steel substrate to BS EN 10147. Usually identified by its leather grain or other finish, although it can sometimes have a smooth finish like polyester coated steel.

The steel substrate is cleaned and pre-treated in a multistage process that ensures optimum adherence of the organic coating. It is then coated with primer and cured before the top coating is applied.

Minimum period to first maintenance is the time elapsed between erection of cladding and that point when, although cohesive and mechanically sound, the coating may need maintenance, This usually means painting due to colour fading. (light colours tend to fade quicker than dark ones) Life expectancy for Plastisol cladding is forty years plus.

Typical applications - roofing, cladding, and other building components, such as flashings, curtain walling, infill panels, partitioning, portable accommodation, cold stores, garage doors etc.

Disclaimer: These colours are representative only. Cross-check with manufacturers samples. Other colours are available subject to size of order and availability.

There are many hundreds of different profiles. SLE Cladding Ltd has a rooflight catalogue containing over 600 different profile and this is not the sum total of them as there are many side cladding profiles for which matching rooflights are not manufactured. Fortunately those in common use are a lot less in number.

Below we use as an illustrations a few of the more popular ones. (Apologies for the over use of the colour blue, these drawings are the only ones available that suitably illustrate the various profiles)

1 metre box profile coverwidth sheets have now become very much the standard in roofing and cladding in the UK, giving strength with the economy of width. Profile depths are usually between 30 & 34 mm deep. SLE Cladding Ltd can supply sheets in many different profiles to any length, with handling and transportation being the only limiting factors

Coverwidths in Corrugated Sheets Corrugated sheets can vary in coverwidth from 2ft to as much as 4ft. Sheets are often described by the number of 3" wide corrugations without counting the last lapping corrugation which can be one or one and a half corrugations. Thus the popular 10 x 3" corrugation sheet covers 2ft. 6" with one no. extra side lap making 11 corrugations, similarly the 12 x 3" corrugated sheet covers 3ft with 13 corrugations. Illustrated above is a 13.5 x 3" corrugation which is the widest sheet normally available.

For a quality long lasting roof it is advisable to place a barrier between the sheets and the purlins on which they rest to prevent any corrosion of the sheets from the purlins. This is most important where livestock are being housed. It applies equally to both metal and timber purlins as timber purlins are often tanalised (pressure treated with chemicals to prevent rot) In the case of existing metal purlins remove any build up of rust. The barrier can be a liberal coating of bitumen paint, plastic tape or other products such as roofing felt cut into strips.

Split Orders

Beware when ordering any colour coated sheeting for a project in stages separated by weeks or months or even days. The subsequent orders will not be cut from the same coil or group of coils and thus there is a strong possibility that there will be a difference in shades between orders. This is beyond the control of both the steel manufacturer and SLE Cladding Ltd.

White coloured sheets

No manufacturer of coated profile sheets (plastisol, polyester & others) will give a warranty as to the exact shade of white on any coil matching previous made coils.

They therefore recommend that on large contracts such as the side cladding of large warehouses or stores with white coloured roofing or cladding sheets, that all the sheets should be purchased as one order and on site the sheets should be shuffled by drawing from more than one pack at a time.

This action should blend in any change of shade between coils and provide a uniform shade of white throughout the building's length.

Storage

For long term storage, Plastisol sheets in pack form MUST be stored in a dry condition in a dry store, preferably heated.
