Frequently Asked Questions
Q1: What is the difference between Q235B and A36 steel coils?
Q235B is a Chinese GB/T grade with a specified yield strength around 235 MPa, while A36 is an ASTM standard grade with similar mechanical properties. Both are widely used in general structures. We can provide both grades depending on your project specification.
Q2: Do you supply Mill Test Certificate with each coil?
Yes, every coil is accompanied by a Mill Test Certificate (MTC) which shows heat number, chemical composition, tensile strength, yield strength, and elongation results. This ensures full traceability of the material.
Q3: What are your standard packing and shipping conditions?
Coils are packed with steel strapping, outer packaging with water-proof material or as customer requirement. We ship from Qingdao port and can arrange container or bulk vessel shipping based on order quantity.
Q4: Can you supply customized thickness, width, or surface treatment?
Yes. We can produce coils within our technical range according to your drawings or specifications. Pickled, oiled, or customized edge conditions are available upon request.
Q5: What is your typical delivery time?
For standard specifications, delivery usually takes about 15–30 days after order confirmation, depending on production schedule and shipping arrangement. We have a dedicated logistics team to ensure on-time delivery.
