304 Stainless Steel Sheet – Brushed Finish | 0.8mm to 4mm Thick

For light decorative or lining applications, 0.8mm–1mm is generally sufficient. For structural brackets, enclosures, or load-bearing panels, 1.5mm–3mm is typically recommended. For heavy-duty fabrication or high-impact environments, 4mm provides the most rigidity. When in doubt, go one step thicker — it's easier to grind down than to reinforce.

Sheets range from 100mm × 100mm (≈3.9" × 3.9") up to 400mm × 400mm (≈15.7" × 15.7"). Rectangular options include 200mm × 300mm (≈7.9" × 11.8"), 200mm × 400mm (≈7.9" × 15.7"), and 300mm × 400mm (≈11.8" × 15.7"). Select your exact size from the variant dropdown above.

304 stainless steel typically has a tensile strength of around 515 MPa (75,000 psi) and a yield strength of approximately 205 MPa (30,000 psi). Actual load capacity depends on thickness, support span, and how the sheet is mounted. For structural or safety-critical applications, consult a qualified engineer.

304 stainless steel is generally suitable for outdoor use in most environments thanks to its self-forming chromium oxide passive layer. However, in coastal, marine, or high-chloride environments, 316 stainless steel is typically recommended for better pitting resistance. For standard outdoor DIY, architectural trim, and sheltered exterior applications, 304 performs well.

Yes. 304 stainless steel is weldable using TIG, MIG, and spot welding methods. It can be cut with an angle grinder, plasma cutter, or metal-cutting blade. For thinner gauges (0.8mm–1mm), tin snips or a nibbler may also work. Always use stainless-specific cutting discs to avoid iron contamination and surface rust.

A brushed finish features fine parallel grain lines created by mechanical abrasion, giving the surface a matte, directional texture similar to a No. 4 finish. To maintain it, wipe in the direction of the grain using a soft cloth and a mild stainless steel cleaner or diluted dish soap. Avoid steel wool or abrasive pads running against the grain, as these can scratch and dull the surface.

Yes. 304 stainless steel has good formability and can generally be bent using a sheet metal brake or press brake. Thinner sheets (0.8mm–1.5mm) bend more easily and may be workable with hand-operated brakes, while thicker sheets (3mm–4mm) typically require a hydraulic press brake. Allow for springback when calculating your bend angles.

304 is the most widely used stainless steel grade and handles most indoor, kitchen, and general outdoor applications well. 316 adds molybdenum for improved resistance to chlorides and salt — making it the better choice for marine environments, chemical processing, or direct saltwater exposure. If your project is indoors or in a standard outdoor setting, 304 is generally the more cost-effective choice.
