Q: Can you provide a material certificate? What does the certificate look like?
A: We provide an original Mill Test Certificate (MTC) issued by the steel mill with every shipment. This certificate includes the heat number, batch number, chemical composition, mechanical properties, and applicable standards. If third-party inspection (such as SGS) is required, it can be commissioned in advance; the inspection fee will be negotiated between both parties.
Q: What are theoretical and actual weight calculations? Which is more cost-effective?
A: Theoretical weight calculation is the weight calculated based on the nominal dimensions and density of the steel (usually 7.85 grams per cubic centimeter). Actual weight calculation is the result of weighing. For standard-length steel plates and sections, the difference is small; for hot-rolled coils and pipes, due to thickness tolerances and trimming, the actual weight is often slightly lower than the theoretical weight. Generally, buyers prefer a
