304 Stainless Steel Thin Plate Band Foil Sheet 0.05mm-1mm Thick Metal Strip Roll

For shimming or gap-filling applications, measure the gap with feeler gauges and select the closest thickness. For wrapping or banding (e.g., pipe insulation straps), 0.1–0.3 mm is typically flexible enough to bend by hand. For structural brackets or spring clips that need to hold a set shape, 0.4–1.0 mm is more appropriate. When in doubt, order one step thinner — it is easier to stack two thin shims than to grind down a thick one.

304 stainless steel has a typical tensile strength of 515–720 MPa, which is adequate for most shim and spacer duties where the strip is in compression rather than tension. It is not a spring steel, so it will deform permanently if bent past its yield point. For applications requiring repeated flexing (e.g., snap-fit clips), consider whether a spring-tempered grade would be more suitable.

304 stainless steel forms a passive chromium-oxide layer that resists rust in most atmospheric conditions, including rain and humidity. However, it is not fully immune: prolonged contact with chlorides (road salt, sea spray) can cause pitting corrosion over time. For coastal or marine environments, 316 stainless steel is the recommended alternative. For general outdoor DIY and garden use, 304 performs well without any additional coating.

Yes, for thinner gauges. Strips up to approximately 0.3 mm can be cut cleanly with heavy-duty scissors or aviation tin snips. Gauges from 0.4 mm to 0.6 mm respond well to tin snips or a rotary tool with a cutting disc. For 0.8 mm and 1.0 mm strips, an angle grinder with a thin cutting disc or a metal shear gives the cleanest edge. Always wear cut-resistant gloves — freshly cut stainless edges are sharp.

304 stainless steel can be used in contact with most metals for short-term applications. For long-term contact, be aware that galvanic corrosion can occur when dissimilar metals are in contact in the presence of moisture — stainless steel is relatively noble, so it will accelerate corrosion of less noble metals like mild steel or aluminium in wet conditions. In dry indoor applications, direct contact is generally not a concern.

For most DIY and light fabrication tasks, a 20 mm wide strip in 0.1–0.2 mm thickness and a 3–5 m length offers the most versatility — it can be cut down to narrower widths, folded, or layered. If you have a specific application in mind (e.g., a 30 mm channel), select the width that matches your slot to avoid waste. Longer rolls (5 m, 10 m) offer a lower per-metre cost and are worth choosing if you anticipate repeat use.

Re-roll the strip loosely and store it in a dry location away from direct contact with carbon steel tools or swarf, which can embed iron particles and cause surface rust spots (tea staining). A zip-lock bag or a cardboard tube works well. Avoid storing near cutting fluids or acidic chemicals. If surface staining does occur, it can usually be removed with a stainless steel cleaner and a non-abrasive cloth.
