Short answer: For cold rolled stainless steel sheet and strip up to 2mm, the purchase decision is about gauge, width, edge and surface working together. Flat sheets (平张) suit panels and cut blanks; slit strip (条) suits narrow roll-to-roll feeding. Match 304/316/430 and the surface (2B/BA) to the downstream use, and put the thickness and width tolerance on the order so every coil and every strip delivers the same.
These thin products feed cookware, kitchen appliances, architectural cladding, food equipment, automotive and stamping. This guide converts a thin-sheet and strip enquiry into a specification a service center can slit, cut-to-length and inspect consistently.
Quick Comparison
| Supply form | When to choose | Typical tolerance concern |
|---|---|---|
| Flat sheet / cut-to-length (平张) | Panels, cut parts, press blanks | Length/width squareness, flatness, camber |
| Slit strip (条) | Narrow widths, roll-to-roll feeding | Width tolerance, burr, camber, coil set |
| Full-width coil | High-volume shearing at your end | Gauge profile across width, thickness |
For thin gauge, the deciding factors are width tolerance in slitting and flatness in cut-to-length. Choose the form that matches how your line actually feeds the material.
What Buyers Should Evaluate
- Define gauge (with tolerance), width, length (or coil weight), surface finish and edge condition (mill vs slit) on the enquiry.
- For slit strip, state acceptable burr, camber and coil set; these control stamping and feeding consistency.
- For flat sheets, confirm flatness and whether it is delivered with or without protective film for surface-critical parts.
Before ordering, confirm the difference between coil, sheet, plate and strip, see cold rolled vs hot rolled stainless steel, and check thickness and width tolerances for the exact gauge and width you plan to buy.
Common Purchasing Mistakes
- Ordering “2mm sheet” without width tolerance, then finding the slit widths run differently to your tooling.
- Assuming all thin strip is burr-free; burr and camber are the top defects in stamping and feeding.
- Choosing the cheapest gauge tolerance and struggling with drawing or welding where thickness control matters.
Agree edge type, burr/camber limits, flatness, film and an approved first-article sample before volume production. Put every critical limit on the written purchase order.
Recommended RFQ Wording
State grade (304/304L/316/316L/430), form (flat sheet or slit strip), gauge with thickness tolerance, width, length (or coil weight) and feeding/edge requirements (mill vs slit, burr/camber limits), surface finish, with/without film, quantity, certificate type (EN 10204 3.1 or 2.2), destination and delivery date.
Describe the downstream use (stamping, drawing, welding, architectural) so the supplier can flag gauge, edge or surface mismatches before cutting. Keep measurable limits on the order, not just in the enquiry email.
How Still Steel Supports the Project
Still Steel supplies cold rolled stainless steel sheet and strip up to 2mm and provides processing such as slitting, cut-to-length and surface finishing, so flat sheets and slit widths can be supplied to your gauge and width at one source. Send the grade, gauge, widths, quantities and application to vip@still-steel.com, or discuss the requirement on WhatsApp.
Frequently Asked Questions
What is the difference between a flat sheet and a slit strip?
A flat sheet is sheared or cut-to-length from coil into large rectangular pieces, while slit strip is slit from coil into narrow widths. Choose flat sheet for panels and cut parts, and slit strip when you need many identical narrow widths roll-to-roll or with tight width tolerance.
Which edges should I specify, mill edge or slit edge?
State it on the order. Mill (rolled) edge is as-delivered from the coil and can have edge defects; slit (trimmed) edge is cut cleanly for better consistency. Burr and camber matter on slit strip, so confirm your acceptable limits with the supplier.
What thickness tolerance should I expect for cold rolled sheet up to 2mm?
Cold rolled thin sheet follows tighter thickness tolerances than hot rolled. Confirm the tolerance against the governing standard (e.g. EN 10088-2 or the mill profile) for the exact gauge, width and grade you need instead of assuming a universal value.
