Frequently Asked Questions (FAQ)
-
Q: What is the difference between Q235B and Q235A?
A: Q235B has stricter requirements for chemical composition and mechanical properties, especially for impact toughness at low temperatures. It offers better performance than Q235A and is widely used for structural applications. -
Q: Can I order coils with a specific inner diameter other than 508mm or 610mm?
A: While 508mm and 610mm are our standard ID options, we can accommodate other diameters subject to production capability and minimum order quantity — please inquire with our team. -
Q: Are these coils suitable for pipe manufacturing?
A: Yes, Q235B hot rolled coil is commonly used for welded pipes, ERW pipes, and spiral pipes. The grade provides good weldability and tensile strength required for pipe forming. -
Q: What surface treatment is applied by default?
A: The standard delivery condition is hot rolled with mill scale. Pickled and oiled surface (with rust prevention) is available as an optional treatment upon request. -
Q: Do you provide third-party inspection?
A: Yes, we support inspection by internationally recognized agencies such as SGS, BV, or others. Third-party inspection can be arranged at the buyer’s cost. -
Q: What is the typical lead time for 25‑ton container orders?
A: For standard specifications, production usually takes 15–20 days after confirmation of order and payment. Custom specifications may require additional time. -
Q: Can I mix different thicknesses or widths in one container?
A: Yes, mixing is possible to optimize your inventory. However, please note that the total weight per container should not exceed 25 tons, and each coil must comply with safe handling standards. -
Q: Is a material test certificate provided?
A: Absolutely. Each batch is accompanied by a Mill Test Certificate (MTC) according to EN 10204 or equivalent standard, showing chemical composition and mechanical properties.
