Frequently Asked Questions (FAQ)

Q: What is the difference between ASTM A36 and A572 steel? A: ASTM A36 has lower yield strength (250 MPa vs 345 MPa for A572) and better weldability, making it suitable for general structural use where higher strength is not critical. A36 is more cost-effective for light to medium loads.
Q: Can you supply this bar in galvanized finish? A: Yes, we offer hot-dip galvanized surface treatment as an optional service. Please specify your requirement during ordering.
Q: What is the minimum order quantity (MOQ)? A: For standard 20mm×6m bars, the MOQ is typically 1 ton (approx. 67 pieces). Smaller quantities may be available upon negotiation.
Q: Do you provide cutting or drilling services? A: Absolutely. We can cut bars to custom lengths (e.g., 3m, 4m) or drill holes for bolting. Additional processing fees apply – contact our sales team for a quote.
Q: How do you ensure product quality? A: We follow ISO9001:2015 quality management procedures. Each batch is tested for chemical composition, mechanical properties, and dimensional tolerances. Mill certificates are provided with every shipment.
Q: What are the typical lead times? A: For stock sizes (20mm×6m), lead time is 7–15 days after order confirmation. For galvanized or processed bars, 15–25 days. Larger volumes may require 30 days.
Q: Can you ship to other ports besides Qingdao? A: Our primary port is Qingdao, but we can arrange delivery to nearby ports like Tianjin or Shanghai upon request. FOB, CIF, and CNF terms are available.
Q: Is this bar suitable for outdoor structures? A: In black finish, it is suitable for indoor or covered environments. For outdoor exposure, we recommend galvanized coating to prevent rust. Alternatively, painting with anti-corrosion primer is an option.
