Frequently Asked Questions

Q: What is the difference between Q235B and Q345B H-beams in construction?

Q235B is a general carbon structural steel, while Q345B is a low-alloy high-strength steel. Q345B offers a higher yield point, making it more suitable for heavy-load structures and allowing for lighter beam sections without sacrificing strength.

Q: Can you provide H-beams that comply with ASTM standards?

Yes, our production lines are fully capable of meeting ASTM, AISI, DIN, JIS, and EN standards. We can provide the necessary mill test certificates to verify compliance with your project specifications.

Q: What fabrication services are available for steel warehouse construction?

We offer a full suite of processing services including precision cutting to length, welding of joints, bending, and punching of bolt holes, ensuring the beams arrive ready for immediate assembly on-site.

Q: How do you ensure the quality of the steel during the export process?

We use standard seaworthy packaging with waterproof paper and steel strips. Additionally, we provide photo and video verification of the product and packaging before the balance payment is made.

Q: What is your minimum order quantity for custom-sized I-beams?

Our MOQ is generally 1 ton. We are flexible and accept sample orders to help you verify the material quality and dimensions before committing to a large-scale procurement.

Q: How long does it typically take from order placement to delivery?

For in-stock items, we can transport goods to the loading port within 7 days. For custom production, the typical lead time is between 15 to 30 days after receiving the deposit.
