ST963 is a profiled metal roofing and cladding profile manufactured with four trapezoidal ribs of 46mm in height. Unique design enhancements stiffen the rib shape to provide industry leading resistance to both wind uplift and point load distortion. Translucent sheeting is available to match.
Superior rib strength resulting in less damage to roof during both construction and serviceable life
Groove at rib apex adds strength
46mm rib height — reduced fixing costs due to shorter screws
ST963 is suitable for a wide range of end uses including roof and wall cladding, ceilings and linings. It can be spring curved in .55mm thickness G550 steel to a minimum radius of 60m. The specific design makes it suitable for high wind zones and all corrosion zones.
Limitations on Use
For structures requiring compliance with NZBC Clause E2, minimum pitch is 3°. Roof runs in excess of 80m should be checked for water run-off capacity. Provision for thermal expansion should be considered for lengths in excess of 18m in steel and 12m for other materials.
