This product is a galvanized carbon steel structural component manufactured from S235JR non-alloy structural steel. It is designed for construction projects that require dependable load-bearing capacity, good weldability, easy fabrication, and improved outdoor corrosion resistance through hot-dip galvanizing. In practical supply, S235JR is the base steel grade under EN 10025-2, while the finished structural tube or fabricated profile is commonly produced to structural hollow-section or fabricated steel requirements depending on the target market and project specification.
S235JR is a widely used mild structural steel grade for metal structures and composite steel-concrete structures. For a U-shaped structural pipe or formed construction member, it offers a balanced combination of strength, formability, and cost efficiency. After hot-dip galvanizing, the zinc coating provides an additional corrosion-protection barrier for exposed service in construction environments.
| Item | Description |
|---|---|
| Base Material | S235JR / 1.0038 carbon structural steel |
| Product Form | U-shaped structural pipe / custom-formed structural tube |
| Surface | Hot-dip galvanized |
| Manufacturing Route | Fabricated from structural steel tube or structural hollow section to drawing |
| Supply Condition | Cut-to-length, formed, welded, drilled, punched, or prefabricated as required |
| Dimensional Range | Custom outer size, wall thickness, leg height, opening width, bend radius, and length |
| Inspection | Visual inspection, dimensional check, coating inspection, and material certificate on request |
| Typical Documentation | MTC / EN 10204 3.1 on request, heat-number traceability, packing list, coating records |
Reliable structural strength for general construction and support applications
Good weldability and fabrication efficiency for cutting, drilling, and forming
Hot-dip galvanized surface for improved atmospheric corrosion resistance
Suitable for outdoor frames, supports, brackets, guard structures, and utility construction
Cost-effective solution for medium-strength structural projects
We address this by aligning the galvanized finish with recognized hot-dip coating standards such as EN ISO 1461, ASTM A123/A123M, or GB/T 13912 where required. These standards define coating requirements and test methods, giving buyers a clear inspection basis instead of relying on appearance only.
S235JR belongs to the EN 10025-2 non-alloy structural steel family and is widely used where weldability and general fabrication are important. For structural tube supply, buyers typically pair the grade with product standards such as EN 10219, ASTM A500, JIS G3444, or GB/T 6728 depending on the project market and fabrication route.
Serious buyers usually focus on heat traceability, mill test certificates, and shipment condition. We support batch traceability and inspection-document supply, and for galvanized cargo we pay attention to dry packing and ventilation because moisture trapped during storage or transport can contribute to white rust on zinc coatings.
The table below shows representative EN 10025-2 heat-analysis maximum values for five related structural grades commonly used for comparison. Actual certified values can vary with thickness class and product form. Fe is the balance.
| Grade | C max (%) | Si max (%) | Mn max (%) | P max (%) | S max (%) | N max (%) | Cu max (%) |
|---|---|---|---|---|---|---|---|
| S235JR | 0.17 | — | 1.40 | 0.035 | 0.035 | 0.012 | 0.55 |
| S235J0 | 0.17 | — | 1.40 | 0.030 | 0.030 | 0.012 | 0.55 |
| S275JR | 0.21 | — | 1.50 | 0.035 | 0.035 | 0.012 | 0.55 |
| S355JR | 0.24 | 0.55 | 1.60 | 0.035 | 0.035 | 0.012 | 0.55 |
| S355J2 | 0.20 | 0.55 | 1.60 | 0.030 | 0.030 | — | 0.55 |
The following table gives representative minimum mechanical properties for related EN 10025-2 grades, using common comparison values for structural sections and products. Exact certified results depend on thickness, section geometry, and delivery condition.
| Grade | Yield Strength Min (MPa) | Tensile Strength (MPa) | Elongation Min (%) | Impact Requirement |
|---|---|---|---|---|
| S235JR | 235 | 360-510 | 24 | 27 J at +20°C |
| S235J0 | 235 | 360-510 | 24 | 27 J at 0°C |
| S275JR | 275 | 410-560 | 23 | 27 J at +20°C |
| S355JR | 355 | 470-630 | 22 | 27 J at +20°C |
