As a rule, sheet steel is a flat piece of metal (made of steel) whose width is significantly larger than its thickness. If the sheet metal is less than 3 millimeters thick, it is called thin sheet metal, and if it is 3 millimeters or more thick, it is called heavy sheet metal

In hot-dip galvanising, a zinc coating is applied to the component by immersing it in molten zinc and then spinning it off. DIN EN ISO 10684 restricts its application to steel fasteners with standard threads ranging from M8 to M64, as well as strength classes up to 10.9 for bolts and 12 for nuts. The average coating thickness for fasteners is 50 micrometres, which ensures corrosion protection for many years.
