Stainless Steel Sheet Bright Polish 1.5mm Thick Many Size Grade A2 304 L50-450mm

Select the size closest to your finished part dimensions, leaving a small margin for cutting. The variant dropdown lists all available sizes from 50mm × 50mm up to 450mm × 450mm. If your project requires a non-standard size, order the next size up and trim to fit using an angle grinder, jigsaw with a metal blade, or laser cutter.

304 grade stainless steel at 1.5mm thickness has a tensile strength of typically 515–720 MPa and a yield strength of ≥205 MPa. It is rigid enough for structural brackets, enclosure panels, and repair patches, while still being formable by hand bending over a straight edge for gentle curves. For load-bearing structural applications, consult an engineer for your specific use case.

304 (A2) stainless steel offers excellent corrosion resistance in most atmospheric conditions, including rain, humidity, and mild industrial environments. It is not recommended for prolonged immersion in saltwater or highly chlorinated environments — for those applications, 316 (A4) grade is preferred. The bright polished finish also helps resist surface staining and oxidation.

Yes. The sheet can be drilled with standard HSS (high-speed steel) drill bits using cutting fluid, and accepts M3–M10 stainless steel fasteners. It is weldable using TIG, MIG, or spot welding processes. Use 308L filler wire for TIG welding 304 stainless. Avoid carbon steel tools that may leave embedded particles causing surface rust.

Each variant combines a specific sheet size with a pack quantity. For example, "100mm × 100mm × 1.5mm / 4" means you receive four sheets of that size. Larger sizes are typically available in smaller pack quantities (1 or 2 pieces), while smaller sizes are available in packs of up to 8. Choose the combination that best matches your project needs and reduces waste.

Yes, for straight cuts an angle grinder with a thin stainless steel cutting disc (1mm) works well. A jigsaw fitted with a bi-metal or stainless-rated blade is suitable for curved cuts. Aviation snips can handle smaller pieces up to about 150mm. Always wear eye protection and gloves, and deburr cut edges with a file or flap disc for a safe, clean finish.

If your project requires a single continuous surface (e.g., a splashback or panel), order one sheet sized to cover the area. If you need multiple identical parts (e.g., brackets, gussets, or patches), ordering a multi-piece pack of a smaller size is more economical and reduces cutting waste. Compare the per-piece price across variants to find the most cost-effective option for your quantity.
