25 x 80 x 15.7 kg Flatbar S275
25 x 80 x 15.7 kg Flatbar S275 is a mild steel flat measuring 25 × 80 mm, used as plate stock for splices, packers, gussets and flitch work. As a flitch plate sandwiched between timber, a flat bar adds substantial bending stiffness while keeping the finished member the same width as the joists either side of it.

At 15.7 kg per metre, one tonne buys roughly 63.7 linear metres. Weight-wise it sits in the everyday working band — the size most frequently specified where span and access have to be balanced against each other. Supplied in grade S275 to BS EN 10025-2, cut to your lengths and delivered worldwide. Heat numbers are traceable back to the rolling mill, with EN 10204 3.1 certificates issued against each delivery.
Typically specified for bracing straps, fabricated brackets, edging and trim to steelwork, timber flitch beams and splice and gusset plates.
Specify whether edges need to be deburred or bevelled; plates going into a visible position usually want both.
