The new way to achieve NCC roofing installation requirements


The LYSAGHT SUPABRIDGE® roofing system provides an innovative and safe alternate solution for compliance to Section J requirements of the National Construction Code (NCC). Section J is applicable to class 2 – 9 buildings.

The integrated LYSAGHT SUPABRIDGE® system replaces the need for the separate purlin bridging and roof raisers used in traditional commercial and industrial metal roof installation.

The system utilises the structural purlin depth to safely accommodate uncompressed blanket insulation and roof safety wire, thereby maintaining roof heights, and full sheeting (uplift) capacities by enabling direct fixing to purlin members.

The complete SUPABRIDGE™ system comprises the following components:

Key Benefits

  • Thermal Insulation performance to meet and exceed NCC Section J requirements resulting in more efficient buildings reducing energy costs.

  • Improved structural performance via direct fixing of LYSAGHT® roof cladding to building structure.
  • Installation connection methodologies that align with industry practice reducing installation effort and cost.
  • Performance tested and backed by industry leaders, Lysaght, Australia’s steel people.
