Roof Safety
Mesh
High-tensile galvanised roof safety mesh for fall protection during roof installation on domestic, commercial and industrial buildings. Constructed from 2 mm galvanised wire exceeding 450 MPa tensile strength, with a 150 mm × 300 mm rectangular grid. Complies with AS/NZS 4389:2015. Becomes a permanent fixture in the building once installed. Also supports foil underlays and synthetic sarking in enclosed roof spaces.
How It Works
Fall Protection System
01
Installed Between Rafters
Roof safety mesh is laid across and fixed to the rafters or purlins before roof cladding is installed. It spans the full bay width, providing a continuous fall-arrest surface below the cladding line.
02
Fixed with Mesh Fixing Strips
Pre-punched and folded 2 mm galvanised steel fixing strips are used to tension and secure the mesh to each rafter or purlin. Correct fixing is critical to the structural performance of the system.
03
Supports Underlay
Once fixed, the mesh supports foil underlays and synthetic sarking (e.g. Covertek 407, AIR-CELL Insuliner) in enclosed roof spaces. May also support insulation — check compatibility with the insulation manufacturer.
04
Permanent Fixture
Unlike temporary fall-arrest systems, roof safety mesh becomes a permanent fixture in the building once the roof cladding is installed over it. It remains in place for the life of the building.

Primary Fall Protection
AS/NZS 4389:2015 compliant
Roof safety mesh is classified as a primary means of fall protection under AS/NZS 4389:2015. It is designed to arrest the fall of a worker through the roof plane during installation. It does not replace personal fall-arrest equipment (harnesses) where required by WHS regulations.
Permanent vs Temporary
Permanent fixture once cladding is installed
Unlike temporary edge protection or scaffolding, roof safety mesh becomes a permanent part of the building structure once the roof cladding is installed over it. It remains in place for the life of the building and does not need to be removed.
Underlay Support Function
Supports foil and synthetic sarking
In addition to fall protection, the mesh supports foil underlays (e.g. reflective foil laminates) and synthetic sarking (e.g. Covertek 407, AIR-CELL Insuliner) in enclosed roof spaces. It may also support insulation — compatibility must be confirmed with the insulation manufacturer.
Enclosed Buildings Only
Not for exposed structures
Roof safety mesh is only suitable for use in enclosed buildings. It must not be used in exposed structures such as canopies or awnings, as exposure to weather will compromise the durability of the galvanised coating and the structural performance of the mesh.
Weather Exposure Limit
Maximum 7 days unprotected
Once installed, the mesh must not be exposed to sunlight, dust, rain or other weather elements for more than 7 days. Same-day coverage by roof cladding is recommended. Prolonged exposure will degrade the galvanised coating and may compromise the fall-arrest performance.
10-Year Warranty
Subject to installation compliance
Roof safety mesh is warranted for 10 years, provided it is not damaged, is used only within the stated product limitations, is installed in accordance with the written installation instructions, and is compatible with the building structure materials used.
Scope of Use
Suitable Applications
- —Primary fall protection during roof installation — domestic, commercial and industrial buildings
- —Support of foil underlays in exposed roof spaces
- —Support of synthetic underlays in enclosed roof spaces
- —Support of insulation (check compatibility with insulation manufacturer)
- —Steel structure and timber structure roofs
Not Suitable For
- —Exposed structures — canopies, awnings, pergolas
- —Coastal or seashore environments
- —High internal moisture loading buildings
- —Exposure to weather for more than 7 days without cladding coverage
- —Use as a load-bearing platform for heavy roofing machinery or equipment
Applicable Standards
AS/NZS 4389:2015
Roof Safety Mesh
Primary Australian/New Zealand standard for roof safety mesh. Covers performance requirements, dimensional specifications, wire tensile strength, installation requirements and compliance testing for fall-protection mesh used in domestic, commercial and industrial roofing.
AS/NZS 4534:2006
Zinc and zinc/aluminium-alloy coatings on steel wire
Covers the zinc coating requirements for galvanised steel wire used in roof safety mesh. WO2 classification specifies minimum zinc coating mass for wire used in roof safety applications.
NCC (BCA) Volume 1 & 2
National Construction Code
The NCC requires fall protection for workers during construction. Roof safety mesh complying with AS/NZS 4389:2015 is an accepted solution for fall protection during roof installation under the NCC.
WHS Regulations 2017
Work Health and Safety Regulations
Commonwealth and state/territory WHS Regulations require fall protection for work at heights above 2 m. Roof safety mesh is one accepted means of fall protection. Personal fall-arrest equipment (harnesses) may also be required depending on the work method.
