About the product
Trapezoidal panels are produced by roll-forming sheet into a trapezoidal section. The profile geometry increases the bending strength of thin sheet so it can span wider purlin spacings.
A fast and economical solution for agricultural buildings, warehouses and industrial halls, site hoardings and temporary structures.
Trapezoidal sheet and roofing sheet
Trapezoidal sheet used on roofs is also known as roofing sheet. It is roll-formed from galvanized or RAL pre-painted steel; we supply all common trapezoidal profiles and rib types.
Sizes and length
Trapezoidal profiles are named by rib height and rib pitch (e.g. 27/200). Panels are cut to the required length in one piece; 3, 4 and 6 metres are among the most requested lengths. See the trapezoidal sheet sizes guide for profiles and effective width, and the trapezoidal sheet weight calculator for panel weight.
Pre-painted trapezoidal sheet
Pre-painted trapezoidal sheet is made from factory-painted galvanized steel and offers colour options for roofs and walls. See pre-painted steel colours for standard colours. If insulation is also needed, see our sandwich panels.
Trapezoidal sheet prices
The price of trapezoidal sheet depends on sheet thickness, galvanized or pre-painted finish, profile type, panel length and total area. Because steel and raw material prices change frequently, we do not publish a price list; current prices are given as a quote.
