Frequently Asked Questions (FAQ)
-
Q: What is the minimum order quantity (MOQ) for ASTM A36 hot-rolled coil?
A: Our standard MOQ is 25 metric tons per size. However, we can accommodate trial orders of 10-15 tons for new customers. Please contact our sales team for details. -
Q: Can you provide mill test certificates (MTC)?
A: Yes, we provide MTC for every coil as per EN 10204 type 3.1, ensuring full traceability of chemical and mechanical properties. -
Q: What surface treatments are available?
A: Standard options include black (as-rolled) and pickled & oiled (P&O). We can also apply anti-corrosion oil or rust preventive coating upon request. -
Q: How long does delivery usually take?
A: For standard sizes, delivery is typically 15-20 days after order confirmation. For custom widths or special treatments, lead time may be 25-30 days. -
Q: Do you offer slitting or cutting-to-length services?
A: Yes, we have in-house slitting and shearing lines to produce custom widths and lengths. Please specify your requirements when placing an order. -
Q: Is your product suitable for outdoor structural applications?
A: ASTM A36 is commonly used for structural steel fabrication such as bridges, buildings, and industrial frames. For outdoor use with moisture exposure, we recommend pickled & oiled or a protective coating to reduce surface rust. -
Q: What is the coil weight range?
A: Coil weight typically ranges from 10 to 30 tons, depending on thickness and width. We can provide smaller coils (5-8 tons) for special handling equipment. -
Q: How do you ensure the quality of the coils?
A: Our ISO9001 certified quality system covers raw material sourcing, production monitoring, and final inspection. We also conduct third-party inspection (e.g., SGS, BV) if required by the buyer.
