Frequently Asked Questions
-
What is a Mill Test Report?
A Mill Test Report (MTR) is a certified document issued by the steel mill that lists the chemical composition, mechanical properties, heat treatment details, and testing results for a specific batch of steel. We issue it with every shipment to ensure full traceability and quality proof. -
Can you cut the steel coil according to my size?
Yes. We provide technical cutting support including slitting, cut-to-length, and custom shapes. Simply send us your drawings or dimensions and we will advise on optimal cutting methods and tolerances. -
What steel grades are available?
We mainly supply A36, SS400, and Q235B, but you can also request other equivalent grades. Please contact us with not more than 40 characters for your required grade description, and we will confirm availability. -
How is the warranty defined?
Our 12-month warranty covers manufacturing defects such as lamination, inconsistent hardness, or dimensional deviations found under normal processing conditions. It does not cover improper handling, abuse, or corrosion caused by uncontrolled environment. -
What is the minimum order quantity?
MOQ is typically 1 x 20ft container for standard coils. For trial orders we can be flexible. Contact us to discuss based on thickness, width, and cutting requirements. -
Do you support third-party inspection?
Yes. We welcome and accept third-party inspection from SGS, BV, TUV or any agency you nominate. Inspection details can be arranged before shipment. -
