Pans & Swages
It is standard Steelformers practice that the pans are run with swages, for extra rigidity and strength, and for reducing wind-driven roof noise. If the customer wants to run the pans without swages to achieve a smooth finish, it is at the discretion of Steelformers and is judged on a case by case basis. In very high and extra-high wind zones it is mandatory to run the pans with swages.
Fasteners & Fixings
Quattro 25mm Double Standing Seam roofing must always be installed over a solid plywood substrate, with purlin supports underneath. The required plywood substrate must be a minimum 12mm thick plywood sheet, structurally fixed to the frame in accordance with the New Zealand Building Code.
The following shows the recommended clip fixing positions per wind zone.
ALL WIND ZONES
450mm purlin centres, with min. 12mm ply substrate
Clips fixed at 405mm centres
N.B. In very high and extra-high wind zones it is mandatory to run the pans with swages.
