Cold-Rolled
Finishing mills roll cold coils of pickled hot-rolled sheet to make the steel thinner, smoother, and stronger by applying pressure, rather than heat. Stands of rolls in a cold-reduction mill are set very close together and press a sheet of steel from one-quarter inch thick into less than an eighth of an inch, while more than doubling its length.
A.H.S.S. — High-Strength
(AHSS) are complex, sophisticated materials, with carefully selected chemical compositions and multiphase microstructures resulting from precisely controlled heating and cooling processes. Various strengthening mechanisms are employed to achieve a range of strength, ductility, toughness, and fatigue properties.
Pre-Painted
Prepainted metal is produced by adding paint or film coating to strip metals, primarily steel and aluminum, on a continuous basis. This process is called coil coating.
Aluminum
Element No. 13 of the periodic system; Atomic weight 26.97; silvery white metal of valence 3; melting point 1220 (degrees) F; boiling point approximately 4118 (degrees) F.; ductile and malleable; stable against normal atmospheric corrosion. Aluminum is used extensively in articles requiring lightness, corrosion resistance, electrical conductivity, etc.
High Carbon
Steel with more than 0.3% carbon. The more carbon that is dissolved in the iron, the less formable and the tougher the steel becomes. High-carbon steel’s hardness makes it suitable for plow blades, shovels, bedsprings, cutting edges, or other high-wear applications.
Galvanized
Steel coated with a thin layer of zinc to provide corrosion resistance in underbody auto parts, garbage cans, storage tanks, or fencing wire. Sheet steel normally must be cold-rolled prior to the galvanizing stage. Steel is run through a molten zinc coating bath, followed by an air stream “wipe” that controls the thickness of the zinc finish.
Pickled & Oiled
Process that cleans a steel coil of its rust, dirt and oil so that further work can be done to the metal. When hot-rolled coils cool, rust forms on the unprotected metal; often coils are stored or transported while exposed to outside air and water. Through a continuous process, the steel is uncoiled and sent through a series of hydrochloric acid baths that remove the oxides (rust). The steel sheet is then rinsed and dried.
Hot-Rolled
A coil of steel rolled on a hot-strip mill (hot-rolled steel). It can be sold in this form to customers or further processed into other finished products.

Coated
The process of covering steel with another material (paint, tin, chrome, and zinc), primarily for corrosion resistance.
