When a job calls for serious span and load capacity, 290x45mm is where you land. It carries the same F7 structural rating and H3 LOSP treatment running through this whole range, but at a depth built for the heavier end of framing work — long bearers, main beams, anything that can’t afford to flex under load. The LOSP treatment does its job quietly here too, keeping rot, decay and termites out of the equation in outdoor, above-ground conditions, and because it’s a solvent-based treatment rather than a water-based one, the timber comes off dry and ready to coat, not sitting around waiting to dry out first. It’s kiln dried on top of that, so lengths stay true and you’re not fighting warp or twist once it’s up. For anything from a large-format deck to a carport spanning a full car length, this is the size that carries the weight without needing extra props or closer spacing.
