DiamondSteel© Deck Frame Systems bring revolutionary durability to outdoor living spaces with frames that never rot, warp, or burn. Our prefabricated steel frames install in days and last for decades with zero maintenance. Experience the freedom of decking that's truly built to last.
Prefabricated frame sections arrive ready to assemble, reducing construction time by up to 75% compared to timber framing. No on-site cutting means no waste, no sawdust, and no delays – just quick, clean assembly with basic tools.
Our steel deck frames never require painting, sealing, or chemical treatments throughout their 25-year warranty period. This eliminates the ongoing costs and effort associated with timber deck maintenance, saving thousands over the deck's lifetime.
Our galvanised G550 steel frames are engineered to withstand Australia's harshest outdoor conditions without degradation. Unlike timber that rots, warps, or attracts termites, DiamondSteel© deck frames maintain structural integrity through decades of sun, rain, and temperature extremes.
All Con-form Group components are backed by a comprehensive
25-year warranty, reflecting our confidence in superior engineering and manufacturing excellence.
