Key Specifications and Standards
- Standards: ASTM / EN / JIS (e.g., ASTM A240/A36, EN 10088/10025, JIS G4304/G3131).
- Surface options: 2B, BA, No.4, HL, mirror; galvanized (electro / hot‑dip).
- Processing: hot‑rolled, cold‑rolled, annealed & pickled, welded or seamless.
- Typical services: slitting, shearing, cut‑to‑length, drilling, beveling, deburring.
- Documentation: MTC, CO, packing list with net/gross weight and heat numbers.
Typical Applications
Construction, machinery, automotive, energy, enclosures and fencing, food equipment (for stainless), and general fabrication. Match grade and finish to corrosion, strength, and appearance requirements.
Selection Guide
- Use certified material with Mill Test Certificate (MTC).
- Confirm standards (ASTM/EN/JIS) and tolerances per drawing.
- Match surface finish to application (2B/BA/No.4/galvanized).
- Specify dimensions and acceptable deviation upfront.
- Plan packaging and corrosion protection for transit.
Processing, Packaging and Logistics
We adopt edge protection, waterproof wrapping, rust‑inhibiting paper, fumigated pallets, and strapping suitable for sea freight. Loading photos and weight lists are provided for each shipment.
FAQs
Q: What lead time can I expect?
A: Typically 7–15 days ex‑works for standard sizes; custom processing may extend the schedule.
Q: Can you provide cut‑to‑size service?
A: Yes. We slit, shear, cut, drill, bevel and deburr to drawing to reduce waste and speed installation.
Q: How do you ensure quality?
A: Incoming inspection, process control, and final inspection with traceable heat numbers; third‑party inspection is available.
Q: Do you support small trial orders?
A: We support pilot quantities with consolidated shipping to control cost.
All values are typical and for guidance only; confirm with the datasheet and purchase order before production.
