Frequently Asked Questions
- What is the difference between hot-rolled H-beam and welded H-beam? Hot-rolled H-beams are formed in a single rolling process, while welded H-beams are fabricated by welding steel plates in an H shape. Our product is a welded H-beam made from hot-rolled Q235B plates, offering flexibility in dimensions and enhanced strength.
- Is the galvanized coating environmentally friendly? Yes, the hot-dip galvanizing process uses zinc, which is recyclable, and the coating provides long-term protection, reducing the need for maintenance and replacement.
- Can you provide beams with custom lengths? Absolutely. We can cut beams to any length between 6m and 12m, or even longer upon request. Please contact us with your specific requirements.
- What is the minimum order quantity (MOQ)? Our MOQ is typically 10 tons, but we can accommodate smaller orders for sample or trial purposes. Contact us for details.
- How do you ensure the quality of the weld? We use advanced welding techniques (SAW or GMAW) and perform non-destructive testing (NDT) on each beam to ensure weld integrity and strength.
- What is the lead time for delivery? Standard production takes 15-20 working days for orders up to 50 tons. Larger quantities may require additional time. We commit to on-time delivery.
- Do you offer any certifications or test reports? Yes, we provide mill test certificates and ISO9001 certification documentation with each shipment.
- Can the galvanized surface be painted or coated further? Yes, the galvanized surface provides an excellent base for additional coatings, such as epoxy or polyurethane, if required for aesthetic or special protection purposes.
