Galvanized Welded Roof Safety Mesh for Fall Protection

Three rolls of galvanized welded roofing safety mesh on the background.
RSM-1: Roof safety mesh with anti-corrosion and UV stabilized is used for housing roof construction.

Roof safety mesh is formed by welding of zinc coating wires using electric resistance techniques under pressure. Welded roof safety mesh is a primary means for fall protection when persons working at heights in domestic, commercial and industrial building applications and housing roof construction that use metal or timber purlins, or a tested supporting member.

Roof safety mesh coverage

Roof safety mesh shall be installed over the entire roof area, including penetrations, and remain in place for fall protection.

Standard roofing safety mesh complies with

Our roof safety mesh complies with Australian/New Zealand - standard AS/NZS 4389:2015 roof safety mesh.

Welded roof safety mesh features

  1. The wires are clean, smooth and free from defects detrimental to its subsequent processing and end use.
  2. Wire with zinc coating and UV stabilized.
  3. Mesh construction shall be formed by welding of wires using electric resistance techniques under pressure.
  4. Apart from the cut ends, roof safety mesh is clean and free of defects, sharp edges, burrs and similar imperfections that may cause injury to the handler or installer.
