WS trapezoidal roof & wall sheets

One profile family for roofs, walls and ceilings

Trapezoidal sheets are the most widely used cladding for pre-engineered and industrial buildings. Deeper 5- and 6-rib profiles span further between purlins and girts; 7-, 9- and 11-rib profiles give a finer look for walls and smaller buildings; the shallow 13-rib profile is used for ceilings and liners.

Sheets are fixed through the crest or valley with self-drilling screws and sealing washers – see roof sheeting and wall sheeting.

Coil width for all trapezoidal profiles is 1200 mm. Spans depend on thickness, loads and the number of spans – ask for the span table of the selected profile.

Fixing and laps

Roof: fix through the crest with sealing washers; side lap one rib
Wall: fix through the valley; side lap one rib
End laps on roofs at least 150 mm with sealant, on walls 100 mm
Use foam closers at eaves and ridges

자주 묻는 질문

Which profile is best for a warehouse roof?

The deeper 5-rib profiles (WS 1000-32-5, WS 1035-28-5) span furthest between purlins and drain heavy rain best; finer profiles suit walls and small buildings.

Can the same profile be used for roof and wall?

Yes – most profiles are used for both; WS 900-39-6 is a wall profile and WS 1085-9-13 is for ceilings and liners.
