Heavy-duty 2.0mm gauge steel angle brackets for general-purpose 90 degree joints and reinforcement in timber and light structural framing. Each L-shaped bracket is described by its leg width (A x B, the two arms) and overall length (C), so the same style can serve as a compact corner gusset or a long reinforcing strip, depending on the size chosen.Made from pre-galvanised Z275 steel (DX51D + Z275), with a zinc coating of not less than 275g per square metre applied to both sides, about 20 microns thick, for reliable general-purpose corrosion resistance. The 5mm fixing holes are pre-punched at the factory, so the bracket can be offered straight up to the joint without drilling the bracket itself.Load data: characteristic load-carrying capacity (Pmax,k) of 15.6kN for a complete joint made with two brackets of this size, so the force per bracket is half of this value. Manufacturer's data, determined by tests or calculation for pressure loading, with timber of 350kg per cubic metre density and the brackets fixed to the manufacturer's nailing pattern.Specification:Size: 80 x 80 x 60mm (leg width A x B, overall length C)Material: 2.0mm gauge pre-galvanised Z275 steelFixing holes: 24 pre-punched, 5mmApprox. weight: 140g per bracketFixing: to timber with 4mm connector nails or 5mm Torx connector screwsFitting: hold the bracket in the internal or external corner with each leg flush against its face, mark the holes through the pre-punched pattern and fix to the timber with 4mm connector nails or 5mm Torx connector screws. For a longer joint, choose a longer bracket in the same leg width rather than fitting two short brackets end to end.Typical uses include shelving and furniture assembly, general timber framing, light structural bracing, workbench and rack construction, and fence and decking repairs. Fifteen sizes cover leg widths of 40mm, 60mm, 80mm and 100mm and lengths from 40mm to 200mm.
