What This Material Is For
Carbon steel plate in ASTM A36, JIS SS330, SS400, DIN S235JR, S275JR and S355JR grades is supplied in thicknesses from 0.1 to 60mm, widths from 20 to 2500mm, and lengths from 50 to 1200mm, with custom sizes available. Jialu holds these grades across a single stock list, so a project requiring A36 for structural framing, S275JR for pressure vessel shells, and S355JR for heavy-duty base plates does not need to be split across multiple mills, inspection dates or shipment schedules. Plate is available in mill finish, hot-rolled or cold-rolled, depending on the grade and thickness range.
Why Buyers Choose It

|---|---|
| Thickness | 0.1mm to 60mm, or customized |
| Width | 20mm to 2500mm, or customized |
| Length | 50mm to 1200mm, or customized |
| Surface Finish | Mill finish, hot-rolled, cold-rolled |
| Standards | ASTM, JIS, DIN, EN |
| Weldability | Good weldability across all listed grades |
| Mechanical Properties | Tensile strength, yield strength and elongation per grade specification |
| Processing | Cutting, shearing, drilling, bending and machining available on request |
Materials
- ASTM A36 for general structural use where moderate strength and good weldability are required
- JIS SS330 and SS400 for structural and mechanical applications in Japan and export markets
- DIN S235JR for basic structural duty in European projects
- DIN S275JR for higher strength and improved toughness in structural and pressure applications
- DIN S355JR for high-strength structural components requiring good impact resistance and weldability
Manufacturing Route

- Cutting, shearing, drilling and machining available as value-added services
- Packing and marking arranged to suit destination port and inspection regime
How It Compares With The Alternatives
| Low-alloy steel plate | Carbon steel is cheaper and easier to weld; low-alloy is needed only for higher strength, wear resistance or low-temperature toughness |
|---|---|
| Stainless steel plate | Carbon steel is significantly lower cost; stainless is required only in corrosive environments |
| Galvanized steel plate | Carbon steel is plain; galvanized adds corrosion protection but increases cost and affects welding and coating |
Buying Guide
- Start with the project’s design standard (e.g., ASTM, DIN, JIS) and select the grade family accordingly
- Specify thickness, width and length in the enquiry to confirm availability
- For structural applications, confirm whether yield strength or impact resistance drives the grade choice
- For pressure vessels or high-stress components, confirm if S275JR or S355JR is required over A36
- Send the size table with the enquiry to avoid delays due to unavailability in certain dimensions
