{"product_id":"roof-bloc-300","title":"Roof Bloc 300 - Roof Safety Mesh","description":"\u003cp\u003eRoof Bloc 300 is Australian made galvanised roof safety mesh, 300 mm by 150 mm aperture, designed to comply with AS\/NZS 4389:2015 and tested to Appendix A of that standard by a NATA accredited laboratory. It goes across the purlins or battens and is fixed down before the roof sheets, so it is in place while anyone is still working above the ceiling.\u003c\/p\u003e\n\u003ch3\u003eWhat it is for\u003c\/h3\u003e\n\u003cp\u003eThe primary job is fall protection for people working on a steel or timber framed roof. The secondary job is supporting synthetic underlay in enclosed roof spaces and foil underlay in exposed ones. It can also support insulation, but check the intended use with the insulation manufacturer first, because not every product is meant to be carried on mesh. \u003ca href=\"\/blogs\/blog\/roof-safety-mesh-requirements-australia\"\u003eRoof safety mesh: when is it required\u003c\/a\u003e covers where mesh is the right control and what the standard actually specifies.\u003c\/p\u003e\n\u003ch3\u003eSpecification\u003c\/h3\u003e\n\u003cp\u003eWire is 2.0 mm, galvanised to AS\/NZS 4534:2006 W02, with line wires at 500 MPa minimum tensile and cross wires at 450 MPa minimum.

The 900 mm and 1200 mm widths are made to special order, and cut to length rolls are available, so ask if your run does not divide neatly.\u003c\/p\u003e\n\u003ch3\u003eLimits worth knowing before you order\u003c\/h3\u003e\n\u003cp\u003eNot recommended for coastal or seashore sites, or buildings with a high internal moisture load. It is rated for fall protection and underlay support, not as a structural element. Compliance holds only while the mesh is undamaged and installed to the written instructions, by or under the supervision of a licensed builder, so do not use mesh that has been kinked or cut in transit.\u003c\/p\u003e\n\u003cp\u003eFull wire and compliance figures are in the table below.\u003c\/p\u003e","brand":"Austral Wire Products","offers":[{"title":"1800x50m (90m2)","offer_id":45225011183798,"sku":"SQ2764798","price":99.75,"currency_code":"AUD","in_stock":true},{"title":"2250x50m (112.5m2)","offer_id":45225011216566,"sku":"SQ2274724","price":130.15,"currency_code":"AUD","in_stock":true},{"title":"2400x50m (120m2)","offer_id":45225011249334,"sku":"SQ8770860","price":137.75,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0732\/3995\/3590\/files\/roof-bloc-300-safety-mesh-rolls.jpg?v=1786455904","url":"https:\/\/awbm.com.au\/products\/roof-bloc-300","provider":"AWBM","version":"1.0","type":"link"}
