Steel Sheet Buyers Guide: Gauges, Grades and Finishes

Steel Sheet Buyers Guide: Gauges, Grades and Finishes

Short answer: Buy steel sheet by converting gauge to millimetres, picking cold-rolled for smooth formed parts or galvanized for corrosion resistance, then confirming flatness and finish, with coil supply in our Coil Supplier and thickness planning in our MOQ and Lead Time Guide.

Gauge Versus Thickness

Gauge is an older measure; always also state thickness in mm to avoid confusion, and link sizing to our Steel Coil Buyers Guide for coil stock.

Pick Grade and Finish

Cold-rolled sheet suits painting and forming; galvanized suits outdoors; finish options are in our Surface Finishing Guide and grades in our Galvanized Steel Buyers Guide.

Flatness and Formability

Request flatness class and bending radius for deep drawing; strength data is in our Metal Strength Comparison.

Certification

Confirm the MTC with our Mill Test Certificate Guide and inspection from our Third-Party Inspection Guide.
