304 Stainless Steel Thin Plate Sheet 200x300mm Thick 0.02/0.03/0.04mm-1mm

For machine tool shimming and bearing housing alignment, 0.05–0.2mm is the most commonly used range. Ultra-thin gauges (0.02–0.04mm) suit fine optical or instrument work, while 0.3–0.5mm works well for heavier structural shimming. If you're unsure, 0.1mm is a versatile starting point that can be stacked.

At gauges below 0.1mm, the sheet is best used as shim stock or foil — not as a load-bearing structural element. From 0.5mm upward, the sheet has sufficient rigidity for light brackets, guards, and enclosure panels. For structural applications requiring higher strength, consider 316 or duplex grades.

304 stainless steel performs well in most indoor and sheltered outdoor environments. It resists moisture, humidity, and mild chemical exposure. In coastal or chloride-rich environments (e.g., near saltwater), surface staining can occur over time; 316 grade offers better chloride resistance for those conditions.

Yes. Gauges up to 0.3mm can be cut cleanly with sharp tin snips or a craft knife and steel rule. Thicker gauges (0.4–1mm) are best cut with a metal shear, angle grinder with a thin cutting disc, or laser cutter. Avoid using tools designed for mild steel only, as stainless work-hardens quickly.

The sheet fits within the A4 work area (210×297mm) with a small margin. Most desktop CO₂ and fibre laser cutters with an A4 or larger bed can process this sheet directly. Vinyl cutters are not suitable for metal — use a laser or mechanical shear instead.

Each variant is sold as 1 piece. To order multiple thicknesses, add each variant to your cart separately. If you need larger quantities or custom sizes, please contact us to discuss options.

304 is the standard general-purpose grade, suitable for most indoor, light outdoor, and non-chloride environments. 316 adds molybdenum (2–3%), giving it significantly better resistance to chlorides, salt spray, and certain acids. For most shimming, fabrication, and hobby uses, 304 is sufficient and more cost-effective.
