1mm and 1.5mm sheets are suited for decorative panels, splash-backs, and light-duty covers where rigidity is provided by the surrounding structure. 2mm is a common choice for brackets, guards, and structural plates that need to hold shape under moderate load. 3mm is appropriate when the sheet itself must carry load or resist impact without additional backing.

304 SS has a tensile strength of approximately 515–620 MPa and a yield strength around 205 MPa, which is adequate for many light structural applications such as brackets, gussets, and reinforcement plates. For load-bearing structural members, consult an engineer to confirm the gauge and size meet your specific load requirements.

Grade 304 resists oxidation and general atmospheric corrosion well in most indoor and sheltered outdoor settings. However, it is not recommended for direct exposure to saltwater, chlorinated water, or coastal environments without additional surface treatment. For those conditions, 316-grade stainless steel is a better choice.

Yes. 1mm and 1.5mm sheets can be cut with aviation snips, angle grinders with a stainless-rated disc, or a jigsaw with a bi-metal blade. 2mm and 3mm sheets are best cut with an angle grinder, cold saw, or plasma cutter. Always use cutting fluid when drilling to extend bit life and prevent work-hardening at the cut edge.

Yes. 304 stainless steel is readily weldable by TIG and MIG processes. Use 308L filler wire for best results. Avoid using carbon steel wire or tools that have contacted carbon steel, as cross-contamination can cause surface rust at the weld zone. Back-purging with argon is recommended for full-penetration welds on thinner gauges.

Order the next size up from your finished part dimensions to allow for saw kerf, edge cleanup, and any layout margin. For example, if your finished part is 90×90mm, the 100×100mm sheet gives you approximately 5mm of margin on each edge — enough for most cutting and deburring operations.

These sheets are cut from flat-rolled stock and are packaged to maintain flatness in transit. Minor handling bow can occur on thinner gauges (1mm) over larger sheet sizes; this typically self-corrects when the sheet is clamped or fastened in place. If dead-flat tolerance is critical, a light pass on a surface plate or press is recommended before precision layout work.

The 2-piece option is useful when you need a matched pair for symmetrical builds (e.g., two side panels, two mounting plates) or want a spare in case of a cutting error. The 1-piece option suits single-part prototypes or situations where you only need one finished piece and want to minimize material cost.
