Frequently Asked Questions (FAQ)
-
Q: What is the minimum order quantity (MOQ) for this carbon steel coil?
A: Our standard MOQ is 25 metric tons per specification. However, for trial orders, we can accommodate smaller quantities subject to negotiation. -
Q: Can you supply coils with a thickness of exactly 2mm or 12mm?
A: Yes, we can produce coils with thicknesses ranging from 2mm to 12mm, including intermediate values. The thickness tolerance is ±0.25mm for standard products. -
Q: Are these coils suitable for welding?
A: Absolutely. S235JR steel has excellent weldability and is commonly used in welded structures. We recommend using appropriate welding procedures for best results. -
Q: What is the typical lead time?
A: For standard specifications, the lead time is approximately 15–20 days after order confirmation. Customized dimensions may require 25–30 days. -
Q: How do you ensure the coils are not damaged during shipping?
A: We use multiple layers of protection: inner waterproof paper, outer steel sheet wrapping, and steel strapping. The coils are securely packed in containers or on flat racks. -
Q: Do you provide mill test certificates?
A: Yes, each shipment is accompanied by a mill test certificate (MTC) that confirms compliance with S235JR standard and our ISO9001 quality system. -
Q: Can you supply coils with a pickled and oiled surface?
A: Yes, pickled and oiled (P&O) finish is available upon request. This surface is free of scale and offers better corrosion resistance for interior applications. -
