304 Stainless Steel Foil Strip Sheet — Precision Thin Metal for Shimming, Fabrication & DIY
Whether you're a machinist closing a tolerance gap, a fabricator building a heat shield, or a DIYer reinforcing a bracket, finding the right thickness of stainless steel strip in the right length is rarely straightforward. Standard hardware stores carry only a handful of sizes — and ordering custom-cut metal from a service center means long lead times and high minimums. These 304 stainless steel foil strip sheets are stocked in an unusually wide range of thicknesses and widths so you can get exactly what your project calls for, shipped fast from our US warehouse.
Each roll or cut length is made from 304 stainless steel, one of the most versatile corrosion-resistant alloys available. Thickness options run from 0.01mm (≈0.0004") up to 2mm (≈0.079"), and widths are available in 50mm (≈2"), 100mm (≈3.94"), 200mm (≈7.87"), and 300mm (≈11.81"). Length options are 1m (≈39.4"), 2m (≈78.7"), 3m (≈118"), and 5m (≈196.9"). Select your combination using the variant dropdowns above.
Typical applications include precision shimming and gap-filling in machinery, stainless steel banding and strapping for pipe insulation, thin metal backing plates for woodworking jigs, heat-resistant shielding in automotive and HVAC fabrication, and flexible spring-steel-style leaf stock for custom tooling. The consistent rolled finish and tight dimensional tolerances make these strips a reliable choice for both one-off repairs and repeat production runs.
ℹ️
Compatibility Note: These strips are flat stock — no threads, no pre-drilled holes. They are designed to be cut, bent, clamped, riveted, or welded to suit your application. Verify your required thickness and width before ordering; sizes cannot be exchanged once cut.
✅ Key Features of These 304 Stainless Steel Foil Strip Sheets
-
📐Wide Thickness Range — Available from 0.01mm ultra-thin foil up to 2mm structural strip, covering shimming, banding, and light fabrication in a single product line.
-
🦠Corrosion-Resistant 304 Alloy — The 18/8 chromium-nickel composition resists rust, oxidation, and mild chemical exposure, making these strips suitable for outdoor, humid, and food-adjacent environments.

⚠️
Sizing Note: Ultra-thin foils (0.01–0.05mm) are fragile and should be handled with care to avoid creasing. If your application requires a specific surface finish, hardness, or certification (e.g., RoHS, food-grade), please contact us before ordering to confirm suitability.
❓ Frequently Asked Questions
How do I choose the right thickness for my project?
For shimming and gap-filling, thicknesses of 0.01–0.05mm are typically used. For structural brackets or heat shields, 0.1–0.5mm is generally more appropriate. For load-bearing strips or reinforcement bands, 0.5mm and above is recommended. When in doubt, measure the gap or clearance you need to fill and select the closest thickness available. If you need a combination of thicknesses to build up to a target gap, thinner foils can be stacked.
What load or tension can these stainless steel strips handle?
304 stainless steel generally has a tensile strength of around 515 MPa (75,000 psi). Actual load capacity depends on the cross-sectional area (thickness × width) and the nature of the load (tension, shear, bending). For precision or safety-critical applications, consult a mechanical engineer to calculate the specific load rating for your chosen size combination.
Can these strips be used outdoors or in wet environments?
Yes. 304 stainless steel is corrosion-resistant and performs well in most outdoor and humid environments, including light industrial and garden applications. It is generally not recommended for prolonged exposure to saltwater or highly chlorinated environments — for those conditions, 316 stainless steel is typically the better choice. Contact us if you need to confirm suitability for a specific environment.
Do these strips have threads or pre-drilled holes?
No. These are flat strip and foil products with no threads, holes, or pre-formed features. They are designed to be cut, bent, clamped, riveted, or welded to suit your specific application. If you need holes, they can typically be drilled or punched using standard metal-working tools appropriate for the thickness.
How do I convert the dimensions to inches?
Width: 50mm ≈ 2", 100mm ≈ 3.94", 200mm ≈ 7.87", 300mm ≈ 11.81".
Length: 1m ≈ 39.4", 2m ≈ 78.7", 3m ≈ 118", 5m ≈ 196.9".
Thickness examples: 0.01mm ≈ 0.0004", 0.05mm ≈ 0.002", 0.1mm ≈ 0.004", 0.5mm ≈ 0.020", 1mm ≈ 0.039", 2mm ≈ 0.079".
Can I cut or bend these strips at home without special tools?
Thinner foils (0.01–0.1mm) can generally be cut with sharp scissors or a utility knife and bent by hand or over a straight edge. Thicker strips (0.3mm and above) typically require metal shears, a bench cutter, or an angle grinder with a cutting disc. Bending thicker stock may require a metal brake or a vise with a bending bar. Always wear cut-resistant gloves when handling freshly cut edges.
Is this 304 or 316 stainless steel, and does it matter?
This product is 304 stainless steel, the most widely used grade for general-purpose applications including food processing equipment, kitchen fixtures, architectural trim, and industrial fabrication. 316 stainless steel adds molybdenum for enhanced resistance to chlorides and is typically used in marine hardware and chemical processing. For most DIY and light industrial uses, 304 is generally sufficient.
What surface finish do these strips have, and can I weld them?
Ultra-thin foils (under 0.05mm) are typically bright-rolled with a smooth, reflective surface. Thicker strips are generally a 2B (smooth, slightly reflective) or No.4 (brushed) finish. 304 stainless steel is weldable using TIG, MIG, or spot welding processes. For thin foils, laser welding or resistance welding is typically more practical. Contact us to confirm the finish for your specific size if surface appearance is critical.
