Steel sheet coated by immersion in a bath of molten material (known as hot-dip) to protect the base metal (substrate) against corrosion. The most commonly used protective material is zinc. An organic coating (paint, plastic) can also be deposited on the layer of zinc. The zinc-coated steel is often referred to as “galvanised steel”.

Steel that has been wound.

A fuel obtained by the pyrolysis of coal in coke ovens and used as a reducing agent for iron ore in the blast furnace.

Silicon steel in which magnetic properties are practically the same in any direction of magnetism in the plane of the material. It is used for motors, generators, transducers, and magnetic circuits of industrial machinery.

Sheet steel that has been run through a cold-rolling mill.

Equipment that reduces the thickness, or gauge, of flat steel products by rolling steel between alloy steel cylinders without prior reheating. Several roll passes are generally necessary to gradually reduce the steel to the desired thickness.
