Frequently asked questions
What should I include in an SGCC galvanized coil order?
List the applicable standard, substrate grade, coating designation, thickness, width and quantity. Add surface treatment, edge requirements, coil inner diameter, acceptable weight and the documents required for acceptance.
Can I compare SGCC and DX51D using only the product name?
Review each against its own purchasing standard and the requirements of your application. Do not assume direct equivalence from similar product names; obtain approval for any alternative specification.
How are minimum order and lead time confirmed?
Send your grade, size, tonnage and required delivery date. Ask for separate confirmation of stock availability, any production or processing time, and the dispatch date. Transit time depends on destination and shipment terms; the agreed quotation should state the minimum quantity and schedule.
What documents should I request?
List the required material test report, inspection document type and any third-party inspection in your enquiry. Ask which documents apply to your selected material and agree their scope before ordering. A general company certificate does not replace the material test results for the supplied heat or coil.
