Frequently Asked Questions

Q: What is the difference between pre-galvanized and hot-dip galvanized square tubes?
A: Pre-galvanized steel is coated with zinc before the tube is formed, resulting in a thinner, more uniform coating. Hot-dip galvanized after fabrication provides a thicker coating but may have uneven spots. Pre-galvanized is ideal for structural applications where moderate corrosion resistance is sufficient and cost is a priority.
Q: Can I get custom lengths other than 6m or 12m?
A: Yes, we can cut the square tubes to any length you require, typically within a range of 1m to 12m. Please specify your desired length when placing an order.
Q: What is the tensile strength of this 1.2mm wall square tube?
A: For Q195 grade, the tensile strength is approximately 315-430 MPa; for Q235, it is 370-500 MPa. If you require a specific grade or strength level, please let us know and we can supply accordingly.
Q: Is this product suitable for outdoor use?
A: Yes, the pre-galvanized coating offers good resistance to atmospheric corrosion. However, for extremely harsh environments (e.g., coastal or industrial areas), we recommend a thicker galvanized coating or additional protective measures.
Q: Do you provide samples before bulk order?
A: Absolutely. We can provide free samples (shipping cost may apply) for quality evaluation. Contact our sales team to arrange sample delivery.
Q: What is the minimum order quantity (MOQ)?
A: Our MOQ is typically 1 ton per size, but we can negotiate smaller quantities for first-time trial orders. For large projects, we offer competitive pricing and faster lead times.
Q: How do you ensure the dimensional accuracy of the tubes?
A: Our production lines are equipped with precision forming machines and online inspection systems. Each batch is tested for wall thickness, outer dimensions, and straightness before packaging.
Q: What payment terms do you accept?
A: We accept T/T (telegraphic transfer), L/C (letter of credit), and other negotiable terms. For new customers, a 30% deposit is usually required, with the balance before shipment.
