Reinforced structural rigidity: a pressed rib runs across the corner of this galvanised steel bracket, adding genuine stiffness beyond a flat angle bracket and helping the joint resist flex and rotational movement under load, rather than relying on the fixings alone to hold it square. Fits timber, concrete and steel joints: built for 90 degree timber-to-timber, timber-to-concrete or timber-to-steel connections at a consistent 2.5mm steel thickness, so the bracket can be matched to the joint instead of over- or under-specifying one universal size. Suited to heavy-duty structures: the largest size in the range, matched to substantial pergola posts and sleeper retaining walls carrying greater load than a standard bracket is built for. Supplied as a pack of 10 angle brackets measuring 150x150x65mm, 2.5mm thick, finished in a silver galvanised coating, the exact quantity for the joints on your project without buying a larger box than the job needs. Built to the same specification as the rest of the range: DX51D plus Z275 galvanised steel with a Fire reaction class of A1 (non-combustible), for consistent quality across every bracket size in the line. This 150x150x65mm size is CE marked under a European Technical Assessment.
