Stainless Steel Sheet Bright Polish 16mm Thick Many Size Grade A2 304 L50-450mm

Measure the footprint your project requires and select the next size up to allow for any drilling, milling, or edge finishing. For mounting plates, match the plate to your bolt-hole pattern with at least 10–15 mm of edge clearance around each hole. If your required size falls between two options, contact us to confirm availability of custom cuts.

At 16 mm thickness, 304 stainless steel plate has a tensile strength of typically 515–620 MPa and is suitable for moderate structural roles such as machine bases, mounting flanges, and press platens. For high-load or dynamic applications, consult a structural engineer to verify the plate meets your specific load and fatigue requirements.

Grade 304 stainless steel performs well in most indoor environments and light outdoor settings away from salt spray or prolonged chloride exposure. In coastal or high-humidity outdoor environments, Grade 316 stainless steel is generally recommended for superior chloride resistance. For light outdoor use such as covered structures or sheltered brackets, 304 is typically adequate.

At 16 mm thickness, cutting requires an angle grinder with a stainless-rated cutting disc, a cold saw, or a plasma cutter. Drilling should be done with carbide-tipped or cobalt drill bits at low speed with cutting fluid to prevent work-hardening. Avoid standard HSS bits without cutting fluid, as 304 stainless work-hardens quickly and will blunt the bit prematurely.

Yes. 304 stainless is weldable using MIG or TIG processes. For stainless-to-stainless joints, use ER308L filler wire. For stainless-to-mild-steel joints, use a 309L filler wire to bridge the dissimilar metals and reduce the risk of cracking. Always clean the weld area thoroughly before welding to avoid contamination.

Grade 304 stainless steel is widely used in food-processing equipment and is generally considered food-safe when properly cleaned. The bright-polished surface reduces surface roughness, making it easier to clean and less likely to harbour bacteria. For regulated food-production environments, verify compliance with your local food-safety authority's material standards.

A bright-polish finish (also called 2B or mirror-adjacent) has a smooth, reflective surface with lower surface roughness than a brushed (No. 4) or mill finish. It is easier to clean, more resistant to surface contamination, and suitable for decorative or layout-reference applications. A brushed finish shows directional grain and is more forgiving of minor handling marks.
