These HSS (High-Speed Steel \/ hard steel) flat bars are stocked in two thicknesses — 2 mm and 3 mm — and cut to a fixed 300 mm (11.81 in) length, giving you a consistent starting point for brackets, reinforcement plates, edge trim, and custom metalwork.\u003c\/p\u003e\n\u003cp\u003eEach strip is a solid, single-piece flat bar with no welds or joins. Width options span 16 mm (0.63 in) through 200 mm (7.87 in), and thickness is either 2 mm (0.08 in) or 3 mm (0.12 in). The 130 mm wide variant is available in a hardened specification for applications that demand extra wear resistance. Surface finish is a clean mill finish suitable for further machining, painting, or powder-coating.\u003c\/p\u003e\n\u003cp\u003eTypical uses include fabricating custom shelf brackets and wall-mount supports, creating reinforcement gussets for wooden or metal frames, cutting down to size for door-hinge backing plates, and serving as raw stock for small-batch metalworking projects. The fixed 300 mm length makes these flat bar metal strips easy to clamp, drill, and cut on a standard bench vise or drill press.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e🔩\u003c\/span\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Suitable for use with standard metalworking tools — angle grinders, drill presses, bench vises, and tap-and-die sets.
