304 Stainless Steel Shim Sheet Foil Strip — 0.05 to 0.5mm Thick, 300×1000mm Metal Band Roll

Thickness selection depends on the gap you need to fill or the flexibility required. For precision shimming and gaskets, thinner foils (0.05–0.1mm) are generally used. For structural spacers or wear strips, 0.3–0.5mm is typically more appropriate. When in doubt, measure the gap with a feeler gauge first — then select the closest available thickness from the variant options 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). Thin foil gauges may vary slightly due to cold-rolling processes. For load-bearing structural applications, consult a materials engineer to confirm suitability.

Yes. 304 stainless steel offers good corrosion resistance in most outdoor environments, including rain, humidity, and mild industrial exposure. It is generally suitable for outdoor shimming, roofing flashing, and HVAC applications. For highly saline or chloride-rich environments (e.g., coastal or marine), 316 stainless steel is typically recommended instead.

Yes. Because this is a flat sheet product, it can be cut to fit around any bolt pattern — metric (M3–M20 and beyond) or imperial (1/8" to 3/4" and larger). Use a gasket punch, hole saw, or drill press to create bolt clearance holes in the shim material.

Yes. Thinner gauges (0.05–0.2mm) can typically be cut with sharp scissors or a utility knife and bent by hand. Thicker gauges (0.3–0.5mm) generally require metal shears or a score-and-snap method. Always wear cut-resistant gloves — freshly cut stainless steel edges are sharp.

Yes. 304 stainless steel is commonly referred to as 18/8 stainless, indicating approximately 18% chromium and 8% nickel content. It is one of the most widely used austenitic stainless steel grades for general-purpose applications including shim stock, food-contact surfaces, and architectural trim.

0.05mm (≈0.002" or 2 thou) is an ultra-thin foil — flexible, lightweight, and ideal for fine shimming, sealing, or wrapping applications. 0.5mm (≈0.020" or 20 thou) is a stiffer strip better suited for structural spacers, wear plates, or heavier-duty gaskets. Choose based on the rigidity and gap tolerance your project requires.

304 stainless steel is highly resistant to rust and staining under normal conditions. Surface discoloration can occasionally occur if exposed to prolonged contact with iron particles, harsh cleaning chemicals, or high-chloride environments. In most cases, a wipe-down with a mild stainless steel cleaner will restore the surface appearance.
