Compliance
Australian Standards for the current CSA range
The standards that apply to our current construction-supply catalogue: steel roofing, walling, cladding, fasteners, insulation and structural sections. CSA provides compliance documentation on project orders.
The primary standard for installing steel roof and wall cladding. Covers fixing, lapping, minimum pitch and weatherproofing for every profile we supply.
Specifies the steel substrate and metallic coatings (Zincalume, galvanised) beneath COLORBOND paint. Defines coating mass and corrosion classes.
Sets fastener corrosion classes (Class 2, 3 and 4). Determines the correct screw for inland, coastal and severe-marine environments.
Defines wind regions and design wind speeds across Australia. Drives the fastener density and sheet thickness required for each site.
The test that confirms steel roofing is non-combustible, satisfying BAL-12.5 through BAL-FZ roof cladding requirements in bushfire-prone areas.
Governs the design of cold-formed C and Z purlins, girts and steel framing supplied for sheds and commercial buildings.
Sets thermal performance requirements for commercial buildings. Determines insulation and sarking specifications under steel roofing.
Specifies the R-value and properties of reflective sarking and bulk insulation we supply for roof build-ups.
