A useful steel coil request for quotation (RFQ) describes the material you need and how you will process, handle and receive it. Sending only a thickness and tonnage leaves important choices open. Use the checklist below to make quotations easier to compare.
1. Identify the product and exact grade
Start with hot rolled coil, cold rolled coil, galvanized coil, galvalume coil or PPGI / PPGL color coated steel. Give the complete grade and purchasing standard, including the edition when your specification requires it. A commercial product name does not replace a material grade.
If you are still choosing a material, describe the end use, forming or welding process and required surface. Ask for a proposed specification to review before placing an order; do not treat similar grade names as automatic equivalents.
2. State dimensions and coil handling limits
- Thickness and width, with units and required tolerances.
- Whether the dimensions refer to the base steel or the finished coated product.
- Total quantity and the quantity for each size or grade.
- Required coil inner diameter, acceptable outer diameter and minimum / maximum coil weight.
- Slit width, cut length or edge requirements where additional processing is needed.
Match coil dimensions and weight to your equipment. If a value is not fixed, mark it “to be agreed” instead of leaving an ambiguous blank. For sheet orders, include length and bundle weight instead of only coil dimensions.
3. Separate substrate, coating and paint requirements
For galvanized and galvalume material, list the substrate grade and coating designation separately. Include the required surface appearance and treatment. For PPGI or PPGL, also specify the substrate type, color reference, paint system, top and reverse coating thickness, and any protective film requirement. A color name alone is not a complete paint specification.
Review the relevant product specification page, then identify which options you need in the enquiry. Availability, tolerances and processing scope must be confirmed for the chosen combination.
4. Agree inspection, packing and delivery
List the inspection documents and acceptance checks your order needs. Specify coil identification, packing-list details, moisture and edge protection, package weight limits, destination and requested delivery terms. See the steel export packing checklist before finalizing these requirements.
State your requested delivery date, but ask the supplier to confirm the production and shipment schedule. Compare quotes using the same grade, quantity, packing scope and delivery basis.
