S235JR Carbon Steel Plate — Factory Direct Supplier | Huaxia-Steel
Product Overview
S235JR carbon steel plate is a general-purpose structural plate to EN 10025-2 with a minimum yield strength of 235 MPa. It is the everyday workhorse plate for buildings, bridges, machinery and fabrication where moderate strength and excellent weldability matter more than high load capacity. Huaxia-Steel supplies S235JR plates cut to size with EN 10204 certificates and export packing, from single pieces to full project schedules.

Manufacturing Standards
Produced to EN 10025-2 and supplied with EN 10204 3.1 mill certificates. Equivalent grades include ASTM A36, GB/Q235B and JIS SS400. We can match the certificate to your specified standard and arrange third-party inspection, including witnessed 3.2 certificates for project-critical supply.
Dimensional Tolerances
Plate thickness tolerances follow EN 10029 (class A or B as required), with flatness to EN 10051 and edge squareness controlled for clean fit-up. For laser or plasma cut parts we hold tighter profile tolerances and can supply a cut list with each bundle coded to your drawing. Tell us the fit-up standard you need and we will quote the corresponding condition.
Machining and Fabrication
S235JR plates weld and form readily with standard structural procedures and need little or no preheat in normal thicknesses. They are easy to cut by flame, plasma or laser and suit both workshop fabrication and site assembly. For painted structures we can supply shot-blasted and primed plate to save you preparation time and give a better coating base.
Applications
- Building and warehouse structures
- Bridge decks and girders
- Machinery bases and frames
- General fabrication and brackets
- Tank and silo shells
- Non-critical pressure and support parts
Weight and Ordering Reference
A 1 mm-thick plate weighs 7.85 kg per square metre, so a 10 mm x 2000 mm x 6000 mm plate is about 942 kg. We quote by piece, by drawing, or by total tonnage, and we can nest cut parts to minimize offcut waste. Sharing your cut schedule up front lets us optimize plate usage and lower the unit price.
Quality Assurance
Each plate is inspected for thickness, flatness, surface and edge condition. Mill certificates confirm chemistry and mechanical properties, and UT or other NDT can be arranged. Third-party inspection (SGS, BV, TUV) is available for project-critical orders, with documented traceability from heat number to finished plate.
Packaging and Shipping
Plates are bundled, edge-protected and seaworthy packed for export; cut parts are coded and bundled by drawing. We ship FOB, CIF or CFR worldwide with moisture protection for long voyages, and we can consolidate with other products in the same container.
Dimensional Tolerance Reference
| Thickness (mm) | Tolerance EN 10029 A (mm) | Typical use |
|---|---|---|
| 6 – 10 | -0.40 to +0.60 | General fabrication |
| 10 – 20 | -0.50 to +0.80 | Structural, bridges |
| 20 – 40 | -0.60 to +1.00 | Heavy plates |
| 40 – 80 | -0.80 to +1.30 | Thick sections |
| 80 – 150 | -1.00 to +1.60 | Heavy industry |
Thickness tolerance tightens or loosens with the class you specify, and flatness is controlled separately to EN 10051. For laser or plasma cut parts we hold tighter profile tolerances and can supply a cut list with each bundle coded to your drawing. Tell us the fit-up standard you need and we will quote the corresponding condition rather than over-specifying.
Common Order Mistakes to Avoid
- Quoting only thickness without width, length and quantity
- Forgetting the MTC class your client requires
- Mixing mm and inch sizes on the same schedule
- Leaving packing and marking instructions blank
A clear line such as ‘S235JR plate, EN 10025-2, 12 x 2000 x 6000 mm, 40 MT, 3.1 MTC, shot-blasted, CIF Jebel Ali’ prevents all four. Sharing your cut schedule up front also lets us nest parts to reduce offcut waste and lower the unit price.
Why Buy S235JR Plate from Huaxia-Steel
We supply S235JR plate from 6 mm to 200 mm with EN 10204 3.1 certificates, cut to size or as full plates, and we can shot-blast and prime to save you site preparation. Our export packing protects the plates on long voyages, and we consolidate with other steel products to optimise freight. With stock range, fast cutting and documented traceability, we are a single source for both standard and project-specific plate requirements.
Mechanical and Chemical Reference
S235JR plate carries a minimum yield of 235 MPa and a tensile range of 360 to 510 MPa, with elongation of 26 percent minimum, verified on the 3.1 certificate for your specific heat. Chemistry is kept clean for weldability: carbon typically up to about 0.17 to 0.20 percent by thickness, manganese around 1.40 percent max, and phosphorus and sulfur each at 0.035 percent max. For painted or galvanized assemblies these tight impurity limits give predictable surface results and fewer welding problems than dirtier steels.
| Property | Specification (EN 10025-2) | Typical delivered |
|---|---|---|
| Yield strength | 235 MPa min | 250 – 290 MPa |
| Tensile strength | 360 – 510 MPa | 400 – 480 MPa |
| Elongation | 26% min | 28 – 32% |
| Charpy (if requested) | 27 J at 20 C optional | Meets on request |
Cutting and Profile Services
We cut plates by flame, plasma or laser depending on thickness and tolerance, and we can supply CNC-profiled parts directly from your DXF or STEP file so the plate arrives ready to weld. Plasma and laser give cleaner edges and tighter tolerances for fit-up-critical work, while flame cutting is economical for thick, less precise parts. Each cut bundle is coded to your drawing and delivered with a cut list, which simplifies site inventory and reduces the chance of using the wrong piece.
Priming and Surface Preparation
For painted structures we offer shot-blasting to a specified cleanliness grade followed by primer application, giving you a coated plate that needs only final topcoat on site. This saves workshop preparation time and produces a more uniform coating base than field blasting. Tell us the primer type and film thickness your specification requires, and we will match it; for galvanizing instead, we can supply pickled or as-rolled plate suitable for the coating line.
A Practical Ordering Example
A clear enquiry reads: S235JR plate, EN 10025-2, 12 x 2000 x 6000 mm, 40 MT, 3.1 MTC, shot-blasted and primed, CIF Jebel Ali. From that line we confirm stock or rolling schedule, cutting and priming, and return a firm quote with lead time. Sharing your full cut schedule also lets us nest parts across plates to minimize offcut waste and lower the effective unit price on complex projects.
Transit and Site Handling
Plates are bundled, edge-protected and seaworthy packed, with moisture barriers for long voyages and clear marking of grade, heat number and dimensions on every bundle. Cut parts are grouped by drawing and tagged so site crews can identify them quickly. Good packing reduces handling damage and the disputes that follow it, and it is part of why our plates arrive ready to work rather than needing re-inspection and repair on the ground.
Thickness Selection Guide
Choose the thinnest plate that meets the load and the corrosion allowance, because plate cost scales with thickness and weight. For lightly loaded floors and general fabrication, 6 to 12 mm is common; for bridge girders and heavy frames, 20 to 60 mm is typical; for thick industrial members, up to 200 mm is available. Over-specifying wastes material and freight, while under-specifying risks rejection, so confirm the design thickness with your engineer and quote exactly that.
| Application | Typical thickness (mm) | Note |
|---|---|---|
| General fabrication | 6 – 12 | Light frames, brackets |
| Building structures | 12 – 25 | Beams, columns |
| Bridge girders | 20 – 60 | Higher load paths |
| Heavy industry | 60 – 200 | Thick, specialty use |
Welding and Preheat Notes
S235JR welds readily with standard structural procedures and normally needs no preheat at ordinary thicknesses when hydrogen is controlled. For very thick sections or highly restrained joints, a modest preheat of around 50 to 100 C may be specified by the WPS. Because the chemistry is clean, the risk of hydrogen cracking is low, which keeps fabrication simple and fast. We can supply the exact carbon equivalent on the certificate so your weld engineer qualifies the procedure with confidence.
Lead Time and Project Scheduling
Standard thicknesses and widths are often available from stock for quick turnaround, while non-standard sizes or heavy plates may need a rolling slot of several weeks. Sharing your project schedule up front lets us phase deliveries to match your build program and avoid both early storage costs and late-line stoppages. For multi-phase projects we can hold and call off stock against a framework agreement, turning a one-off purchase into a managed supply line.
