| Steel grade and coating |
Ask the supplier to state the steel grade, coating type, and whether the price is for bare, galvanized, painted, or other coated sheet. |
Two sheets with the same thickness can have different corrosion resistance, forming behavior, and cost because of the base steel and coating. |
Can you quote the same sheet size with the exact grade and coating system written on the offer? |
| Thickness, width, and usable sheet area |
Confirm the nominal thickness, width, length, and any tolerance that affects the finished sheet area. |
Steel sheet price is often compared by weight or area, but small changes in thickness and width can change both material cost and coverage. |
Is the quoted price based on weight, per sheet, or per square meter, and what dimensions are included? |
| Surface finish and application fit |
Match the finish to the job, such as roofing, cladding, fabrication, panels, or interior use, and ask about scratches, oiling, passivation, or paint finish requirements. |
A cheaper sheet may need extra treatment or may not suit outdoor exposure, visible surfaces, or forming work. |
What surface finish is included in this price, and is it suitable for the intended environment? |
| Order quantity, packing, and handling |
Check the minimum order quantity, bundle weight, packaging method, edge protection, and whether cutting or slitting is included. |
The sheet price can look low before packing, handling, cutting waste, and damage risk are considered. |
Please separate the material price from packing, cutting, and handling charges in the quotation. |
| Compatibility with fasteners and installation method |
For roofing, panels, or steel structure work, confirm the sheet thickness and coating against the screw type, washer material, and drilling method. |
Incorrect matching can cause poor fixing, leaks, coating damage, or corrosion around holes. |
Which self-drilling or self-tapping screw specification do you recommend for this sheet thickness and coating? |
