Frequently Asked Questions
-
What is the difference between Q235 and other steel grades?
Q235 is a Chinese standard carbon structural steel with a yield strength of 235 MPa. It is equivalent to ASTM A36, offering good weldability and formability for general structural purposes. Its cost-effectiveness makes it a popular choice for building frames and supports. -
Can this pipe be used for underground applications?
Yes, the hot-dip galvanized coating provides excellent corrosion resistance for underground installations. However, for extremely corrosive soil conditions, additional wrapping or coating may be recommended – we can advise based on your project. -
What lengths and diameters are available?
Standard lengths are 6 meters and 12 meters, but we can cut to custom lengths. Outside diameters range from 21.3mm to 219mm (1/2 inch to 8 inches). Please consult our sales team for non-standard sizes. -
Do you provide test certificates?
Absolutely. Each shipment includes a mill test certificate (MTC) with mechanical and chemical properties, as well as confirmation of galvanized coating thickness. Additional third-party inspection (e.g., SGS, BV) is available upon request. -
Is the pipe suitable for welding?
Yes, Q235 steel has excellent weldability. The galvanized coating may need to be ground off at weld points, but the base metal welds easily using standard mild steel welding procedures. -
What is the minimum order quantity (MOQ)?
Our MOQ is typically 5 tons for standard sizes, but we can accommodate smaller quantities for trial orders or sample requests. Contact us for details. -
How long does delivery take?
For standard sizes, production takes 7-15 days after order confirmation. Shipping time depends on destination (e.g., 25-35 days by sea to US West Coast ports). We offer FOB, CIF, and other incoterms. -
Can the pipe be painted or powder-coated?
Yes, the galvanized surface can be painted after proper surface preparation (e.g., etching or using a suitable primer). We can supply pipes with a primed finish if required, though standard is plain galvanized.
