Short answer: Metal gauge numbers run opposite to thickness, with steel and aluminum using different mm values at the same gauge, so always confirm mm or inch on the order; our Steel Sheet Supplier y Aluminum Sheet Supplier stock certified thicknesses.

Reading a Gauge Chart
Gauge is a legacy thickness code; steel and aluminum differ, so convert to mm before ordering. Sourcing is in our Steel Sheet Supplier, Aluminum Sheet Supplier y Metal Strip Supplier.
US vs Metric
US gauge and metric mm coexist; specify mm to avoid error, with density context in our Density Comparison Guide and weight in our Comparación de fuerzas.
Specifying Sheet and Plate
Match gauge to load and forming; bending notes are in our Cutting Processes Guide y Surface Treatment Guide; certify per our Mill Test Certificate Guide.
Common Pitfalls
Do not assume gauge equals mm across metals; confirm tolerance and pack per our Export Packing Guide.
