With our ISO9001 certification and extensive export experience across global markets, we provide a cost-effective solution for pipe manufacturers seeking durable and compliant raw materials.
Our carbon steel coils are manufactured to meet the stringent requirements of ASTM A53 Grade B, which is widely recognized for its suitability in pressure piping, structural applications, and general transportation of gas, water, and oil. The thickness range of 2.0mm to 12.0mm offers flexibility for various pipe diameters, from small diameter precision tubes to large structural pipes. Each coil undergoes rigorous tests including tensile strength, yield point, elongation, and flattening tests to guarantee performance.
- Certified Quality: ISO9001 quality management system ensures consistent production standards.
- Global Reach: Serving North America, South America, Europe, Africa, Asia, and Oceania – reliable logistics partner.
- Flexible Sizes: 2.0-12.0mm thickness, customizable width from 900mm to 1800mm to match your pipe mill requirements.
- Chemical Composition: Carbon ≤0.30%, Manganese ≤1.20%, Phosphorus ≤0.05%, Sulfur ≤0.045% – compliant with ASTM A53.
- Mechanical Properties: Tensile strength ≥415 MPa, Yield strength ≥240 MPa, Elongation ≥30% (in 2 inches).
- Surface Finish: Available in black (as rolled) or pickled and oiled for cleaner welding and reduced scale.
- Coil Weight: Typically 3-10 tons per coil, packaged with inner and outer protection for long-distance shipping.

Frequently Asked Questions
-
Q1: What is the minimum order quantity (MOQ) for this steel coil?
A: Our MOQ is typically 1 full container (around 25 tons) for standard sizes. For trial orders, we can accommodate smaller quantities upon request, subject to availability and price adjustment. -
Q2: Can you provide a mill test certificate (MTC) for each coil?
A: Yes, absolutely. Every shipment includes a comprehensive MTC that shows chemical composition, mechanical properties, and heat number, certified by our ISO9001 quality system. -
Q3: Is the coil suitable for high-frequency welding (HFW) or ERW pipe production?
A: Yes, our ASTM A53 Grade B coils are designed for both HFW and ERW processes. The steel's low carbon content and good formability ensure clean weld joints and consistent pipe quality. -
Q4: What is the typical lead time for order?
A: For standard sizes, lead time is about 15-20 working days after order confirmation. For custom widths or special surface treatments, please allow 25-30 days. We always aim to meet your project schedule. -
Q5: Do you offer free samples?
A: Yes, we can provide small samples (e.g., 300mm x 300mm) for quality evaluation. The sample is free, but the buyer is responsible for shipping costs. Contact us to arrange. -
Q6: How do you ensure the coil surface is free from defects?
A: All coils are inspected visually and with eddy current testing (optional) during production. Surface defects such as cracks, scratches, or lamination are rejected. Our QC team also checks edge condition and flatness before packing. -
Q7: Can you supply coils with a specific width suitable for my pipe mill?
A: Yes, we offer slit or custom-width coils from 900mm to 1800mm. We can also provide widths outside this range by special order. Please provide your exact requirements for quotation. -
Q8: What payment terms do you accept?
A: We accept T/T (30% deposit, 70% against copy of shipping documents), L/C at sight, and other flexible terms for qualified buyers. Our finance team can discuss tailored solutions for long-term contracts.
