Which is the right type of sheet?
Depending on building type, use and appearance, we manufacture and supply 4 different types of profiled sheeting, all of which can be supplied to the exact length necessary in a choice of colours, with the necessary roof lights, flashings, fixings, fillers etc.
- 34/1000 Box Profile Sheeting
- 32/1000 Box Profile Sheeting
- 13/3 Corrugated Sheeting
- 41/1000 Tile Sheet
- Trisomet Insulated Panel Composite Sheet
34/1000 box profiled sheeting, by far our most popular profile for either roof or wall cladding. This profile gives 1 metre width cover when lapped and can be made up to 9 metre lengths (longer by arrangement, depending on transportation). This is our strongest single skin sheet due to its 7 rib 34mm deep profile sections and can be used on roofs at minimum pitch of 4º. It is fixed through the lower part of the profile to the purling using self drilling TEK screws.
32/1000 box profile single skin Sheeting, gives a robust sheet strength with 6 profiles of 200mm pitch across the sheet width and 32mm profile height. Some prefer the appearance of this sheet as it has lower and less profiles. It is made from 1220mm coated steet strip and gives 1000mm actual width cover when lapped. When used in roof applications, construction can be safely undertaken down to a 4 degree pitch using conventional through sheet self-drilling fasteners in lower part of profile. Can be used as a single skin sheeting, over clad of an existing roof or part of a built up insultaled system.
13/3 corrugated sheeting gives a traditional look to either roof or wall cladding, gives 990mm width cover when lapped and can be made up to 6 metre lengths. Not as strong as 34/1000 box profile due to its smaller profile sections so may need closer purlin supports, can be used on roofs at minimum pitch of 10º. Due to its curved shape it is fixed through the higher part of the profile to the purling using either longer self drilling TEK screws or traditional nails and spat washers.
Both 34/1000 profile and 13/3 corrugated sheeting are available with Drip-Stop anti-condensation polyester felt flock on the reverse. This is a well proven cost effective method of stopping condensation dripping from steel roofs in damp cold conditions without going to the expense of using insulated sheeting.
41/1000 tile form roof sheet gives a roof a pan tiled appearance, giving 1 metre width cover when lapped and can be made up to 6 metre lengths. Not as strong as either 34/1000 box profile or corrugated 13/3 due to its stepped sections, requiring purling spacing of 600mm centres, can be used on roofs with a minimum pitch of 12º. It is fixed through the lower part of the tile profile to the purling using self drilling TEK screws.
