Specifications

Scope of use

  • ST963 is suitable for a wide range of end uses including roof and wall cladding, ceilings and linings.
  • For structures requiring compliance with NZBC Clause E2, the minimum pitch is 3°.
  • ST963 can be spring curved in 0.55 mm BMT thickness G550 steel to a minimum radius of 60 metres.
  • Roof runs in excess of 80 metres should be checked for water run-off capacity. Provision for thermal expansion should be considered for lengths in excess of 18 metres in steel and 12 metres for other materials. 

Maintenance

  • Maintenance of steel substrates must be carried out in accordance with New Zealand Steel Specifiers and Builders Guide.
  • Generally, required maintenance of exposed well washed roof areas is rainfall only, with an annual inspection to check on the build-up of any contaminants. Sheltered roof areas, walls, and areas subject to the build up of contaminants will require programmed maintenance to provide design life expectations.
  • Maintenance of other substrates should be in accordance with the manufacturer’s requirements for the specific environment and application.
