Trapezoidal wall sheet
The industrial elevation, done properly.
Profile cross-section — schematic, not to scale
Overview
W18 is the standard industrial wall sheet: trapezoidal, exposed-fixed, fast to erect over sheeting rails, and available in the same coating systems and colours as our roof profiles so a whole envelope can be specified as one material.
It runs vertically or horizontally. Vertical is faster and drains better; horizontal gives a longer, lower reading of the building and lets the sheeting rails run with the frame. Both are covered by the same trim set.
For buildings that need a warmer or quieter interior, W18 pairs with our liner tray system to form a built-up wall with insulation between the two skins.
Same coating systems and colours as our roof profiles, for a single-material envelope.
One profile, two orientations, one trim set.
Pairs with liner trays and insulation to form an insulated wall on site.
