SS400 Coil Supply for JIS Structural Steel Inquiries
SS400 is usually requested when buyers need a JIS general structural steel route. For coil orders, you should confirm whether the buyer needs SS400 structural steel coil, SPHC forming coil, or another steel grade based on the final application.

Confirm whether your order needs structural steel performance or commercial hot rolled coil for forming.
Check Selection Logic →SS400 Coil for Fabrication, Pipe Making and Steel Distribution
The main risk when buying SS400 steel coil is not only price. You need to confirm whether the product route, surface condition, coil weight, width tolerance, MTC and packing method match your downstream production or resale requirement.
For Fabrication Plants
You can confirm thickness, width, coil weight, surface condition and forming or welding requirement before quotation.
For Pipe Mills
You can request slit width, edge condition, coil ID, strip coil packing and repeated supply for welded pipe production.
For Service Centers
You can discuss slit coil, cut-to-length sheets, mixed width orders, stock route and export-ready packing.
For Importers
You can review JIS route, MTC, heat number, coil labels, packing method, shipping marks and loading photos.
SS400 vs Q235, Q355, ASTM A36, S235JR and SPHC
This comparison is for purchasing discussion only. Different standards have different test methods, chemical limits, mechanical requirements and document rules. Final substitution should follow buyer approval, project documents or end-user confirmation.
| Reference Grade / Route | Buyer Usually Means | How It Relates to SS400 Coil | Recommended Action |
|---|---|---|---|
| SS400 | JIS general structural steel route for ordinary structural and fabrication use. | This is the main target grade for this page. | Confirm thickness, width, coil weight, surface condition, MTC, destination and packing requirement. |
| Q235 | Chinese general structural steel route, often used for similar general fabrication discussions. | Q235 is often discussed as a nearby reference, but it should not be confirmed as equal without document review. | Use Q235 only when the buyer accepts the GB route or project documents allow it. |
| Q355 | Higher-strength Chinese structural steel route. | Q355 is normally stronger than general SS400 selection logic and should be treated as a different strength route. | Use Q355 when the design or buyer requires higher strength, not only as a price substitute. |
| ASTM A36 | ASTM general structural carbon steel route, commonly seen in project steel documents. | A36 is a useful structural reference, but SS400 coil should not be quoted as A36 unless the buyer accepts the route and documents. | Ask whether the buyer needs ASTM material documents or only a general structural carbon steel coil. |
| S235JR | EN structural steel grade route for European-style project requirements. | S235JR can appear in similar-grade discussions, but project approval and document type matter. | Confirm whether the order requires EN documents, impact suffix, inspection certificate type or only a reference grade. |
| SPHC | Hot rolled commercial steel coil route for forming, stamping and general processing. | SPHC is not the same purchasing logic as SS400. SPHC is often more about forming route; SS400 is structural steel route. | Ask about final application first: forming/stamping route or structural/fabrication route. |

Common Questions from SS400 Carbon Steel Coil Buyers
What information should I send for an SS400 carbon steel coil quotation?
Send grade, thickness, width, coil ID, coil weight, surface condition, processing requirement, quantity, packing request, destination country or port and required delivery schedule.
Is SS400 the same as SPHC?
No. SS400 is usually discussed as a JIS general structural steel route, while SPHC is commonly used for hot rolled commercial forming coil. The right route depends on your final application.
Can SS400 be compared with Q235 or ASTM A36?
SS400, Q235 and ASTM A36 may appear in similar structural steel discussions, but they should not be treated as automatically interchangeable. Final substitution should be approved by the buyer or project engineer.
Can you supply SS400 coil as slit coil?
Yes. Slitting can be reviewed according to thickness, target slit width, tolerance, edge condition, coil ID, coil weight and order quantity.
Can you provide MTC and export packing?
MTC, heat number, coil labels, packing list, commercial invoice, certificate of origin, waterproof packing, shipping marks and loading photos can be discussed according to order requirements.
