304 Stainless Steel Thin Sheet & Foil Strip Roll — 0.05mm to 3mm Thick

For shimming, gasketing, or precision spacing, foil thicknesses of 0.05mm–0.3mm are typically used. For structural brackets, enclosures, or decorative panels, 1mm–3mm sheet stock is generally the right choice. As a rule of thumb, thinner foil (under 0.5mm) is flexible and easy to cut with scissors or a craft knife, while 1mm and above requires metal shears or a laser cutter.

Quick reference: 0.05mm–0.1mm ≈ 0.002"–0.004" | 0.5mm ≈ 0.020" | 1mm ≈ 0.039" | 2mm ≈ 0.079" | 3mm ≈ 0.118"

This is 304 grade stainless steel, the most widely used austenitic grade. It offers a tensile strength of approximately 515 MPa (75,000 psi) and a yield strength of around 205 MPa (30,000 psi). It is well-suited for light structural, decorative, and precision fabrication tasks.

Yes. 304 stainless steel provides good corrosion resistance in most outdoor and humid environments thanks to its chromium oxide passive layer. It is generally suitable for rain exposure, kitchen splashbacks, and light marine use. For prolonged saltwater or chloride-heavy environments, 316 grade is typically recommended instead.

Yes. The foil variants (0.05mm–0.5mm) can generally be cut with heavy-duty scissors, a utility knife, or a rotary cutter. The thicker sheet variants (1mm–3mm) are compatible with metal shears, angle grinders, jigsaws with metal blades, and laser or waterjet cutters. Standard stainless steel drill bits work for drilling.

Square and rectangular sheet formats (e.g., 100×100mm, 200×300mm) are ideal when you need a flat, rigid piece for brackets, panels, or templates. The strip/roll format (300×1000mm in ultra-thin gauges) is better suited for wrapping, shimming, or applications where you need a continuous length of thin material.

The surface finish is typically a mill finish (2B or similar), which is smooth and slightly reflective. This finish is suitable for most functional applications. If you need a brushed or mirror-polished finish, additional surface treatment would be required after purchase.

Yes. 304 stainless steel is generally weldable using TIG, MIG, or spot welding methods. For the ultra-thin foil variants (under 0.3mm), TIG welding with careful heat control is typically recommended to avoid warping. Soldering is possible with appropriate stainless steel flux.
