Stainless Steel Sheet Bright Polish 5mm Thick Many Size Grade A2 304 L50-450mm

Measure the area you need to cover and select the closest size that meets or slightly exceeds your dimensions. For most standard hob splashbacks, the 300×300mm or 400×300mm options are a practical starting point. If your space is wider, consider ordering two pieces and butting them together with a clean seam.

At 5mm thickness, Grade 304 sheet has a tensile strength typically in the range of 515–720 MPa, which is adequate for light-to-medium load-bearing brackets, shelf supports, and reinforcement plates. For heavy structural applications exceeding these loads, consult an engineer before use.

Grade 304 (A2) stainless steel offers good resistance to atmospheric corrosion and moisture in most outdoor environments. However, it is not fully immune to pitting in high-chloride environments such as coastal or marine settings. For those conditions, Grade 316 (A4) is generally recommended instead.

Yes. A 5mm stainless steel sheet can be cut using an angle grinder with a stainless-rated cutting disc, a plasma cutter, or a jigsaw fitted with a bi-metal blade. Use cutting fluid to reduce heat build-up and extend blade life. Standard HSS drill bits work for holes, though cobalt or carbide-tipped bits will last longer.

The bright polished finish is applied to one face of the sheet. The reverse side has a standard mill finish. If you need a polished appearance on both sides for your application, please contact us to confirm before ordering.

The "Quantitys" variant option lets you select 1 or 2 pieces of the same size. Order 2 if you need a matching pair for symmetrical installations (e.g., two side panels), want a spare in case of cutting errors, or are working on a project that requires identical pieces. Single-piece orders are available for all sizes.

Grade 304 contains 18% chromium and 8% nickel, making it suitable for most general-purpose and indoor applications. Grade 316 adds molybdenum, which significantly improves resistance to chlorides and salt water. For most DIY, fabrication, and kitchen applications, Grade 304 is sufficient and more cost-effective.
