Stainless Steel Flat Bar Strips — Metal Sheet Bars for Crafts, Models & Repairs

Measure the span you need to bridge or reinforce, then add at least 10–15mm on each end for fastening overlap. Available lengths are 100mm (≈3.9"), 200mm (≈7.9"), 300mm (≈11.8"), and 500mm (≈19.7"). When in doubt, size up — flat bar stock is easy to cut down with a metal-cutting blade or angle grinder.

304 stainless steel generally has a tensile strength of approximately 515 MPa (75,000 psi) and a yield strength of around 205 MPa (30,000 psi). Actual load capacity depends on bar dimensions, span length, and how the bar is supported or fastened. For structural load calculations, consult an engineer.

Yes. 304 stainless steel is generally suitable for outdoor and moist environments and resists rust and oxidation well in most atmospheric conditions. For marine or high-chloride environments (saltwater, pool areas), 316 stainless steel is typically recommended instead.

These flat bars ship undrilled, so you can drill and tap to any standard — metric (M3–M8) or imperial (SAE). The bar thickness determines the maximum thread depth you can tap. For example, a 3mm-thick bar can typically accommodate an M3 thread. Always confirm clearance before drilling.

Yes. Thinner bars (3–4mm thick) can typically be cut with an angle grinder, rotary tool, or metal-cutting hacksaw, and bent with a bench vise. Thicker bars (5–8mm) generally require more force or a metal brake. Always wear appropriate PPE — gloves, eye protection — when cutting or bending metal.

For light-duty repairs and crafts, 3×10mm or 3×15mm bars are typically sufficient. For structural brackets or load-bearing applications, consider 5×25mm or larger. When in doubt, choose a wider or thicker bar — you can always drill it to fit your fastener pattern.

304 stainless steel is generally weldable using TIG or MIG welding with appropriate stainless filler wire (e.g., ER308L). Post-weld passivation is recommended to restore corrosion resistance in the heat-affected zone.
