304 Stainless Steel Sheet Plate | Brushed & Polished Finish | 0.05mm–3mm Thick

Match the sheet dimensions to your cut-to-size needs — for example, a 100×100mm (≈3.9"×3.9") plate suits small brackets or shims, while a 300×300mm (≈11.8"×11.8") plate works for larger panels. For thickness, 1mm (≈0.04") is generally suitable for light shielding or decorative use; 2–3mm (≈0.08"–0.12") provides structural rigidity for brackets and supports. Foil variants (0.05–0.5mm) are typically used for shimming, gaskets, or heat shielding.

Grade 304 is the most widely used austenitic stainless steel alloy, containing approximately 18% chromium and 8% nickel. It offers good corrosion resistance in most environments, is non-magnetic in its annealed state, and is generally suitable for food-contact, indoor, and light outdoor applications.

Grade 304 stainless steel is generally suitable for outdoor use in non-marine environments. It resists rust and oxidation well in most weather conditions. For coastal or high-chloride environments, Grade 316 is typically recommended instead.

A brushed finish (also called satin or No. 4 finish) has fine directional grain lines and a matte sheen — it hides fingerprints and scratches better, making it popular for functional and industrial applications. A polished (mirror) finish is highly reflective and is typically chosen for decorative or architectural uses. Please select your preferred finish from the variant options above.

Grade 304 stainless steel has a typical tensile strength of around 515 MPa (75,000 psi) and yield strength of approximately 205 MPa (30,000 psi). For light structural brackets, 2mm or 3mm thick plates are generally adequate. For heavy load-bearing applications, consult an engineer to confirm suitability.

Yes. Thinner sheets (0.05–0.5mm foil) can typically be cut with metal shears or a utility knife. Plates up to 2mm can generally be cut with an angle grinder or jigsaw fitted with a metal blade. Drilling requires HSS or cobalt drill bits and cutting fluid. Bending is possible with a sheet metal brake; thicker plates (3mm) may require a press brake.

Grade 304 stainless steel is widely used in food processing and kitchen equipment and is generally considered food-safe. However, the specific surface finish and any edge treatments should be verified for your intended application. Always confirm compliance with local food-safety regulations before use in commercial food environments.
