Product Q&A

Q:What is your lead time? Do you have stock for standard sizes?

Stock sizes ship in 3-5 working days; custom orders take 15-25 days. Delivery date is fixed in the contract with penalty clauses for overdue shipment.

Q:How do you ensure product quality? What inspection methods do you use?

We follow GB/T 2101 with full traceability and in-line monitoring. Finished products undergo mechanical (tensile/bending/impact) and dimensional tests. Each shipment includes an MTC; third-party inspections (SGS/BV) are available on request.

Q:What certifications does your company hold? Do you have export experience?

We are ISO 9001 and 14001 certified, and can supply to CE/ASTM standards. We export to Southeast Asia, the Middle East, Africa, and South America, and provide all customs clearance documents (certificate of origin, packing list, B/L, insurance, etc.).

Q:What if there are dimensional deviations or quality issues upon arrival?

Notify us within 15 days of arrival with a third-party inspection report and photographic evidence. We respond within 24 hours and, if at fault, offer replacement, return, or compensation as per contract terms.

Q:Can your export packaging prevent deformation and rust during long-distance ocean transit?

We use steel strapping, wooden blocks, 0.15mm waterproof film, and VCI paper. Container lashing secures against shifting. Our damage rate is below 0.5%; transit insurance is available upon request.
