Product Announcement from Ferguson Perforating
Perforated carbon steel has no specified minimum quantity of any alloying element and contains only an incidental amount of any element other than carbon, silicon, manganese, copper, sulphur and phosphorus.
It is the most corrosive and least expensive of the commonly perforated metals.
Carbon steel is either referred to as Hot Rolled, steel that underwent a rolling thickness reduction step while hot, or Cold Rolled, where the steel is cold reduced to the specified thickness. Cold rolling elongates the grains of the steel in the direction of rolling, making the steel hard and brittle. Annealing in a reducing atmosphere recrystallizes the grains, giving the perforated sheet steel the ductility needed for its intended use.
Hot Rolled Pickled and Oiled Hot rolled coil or sheet steel that has been descaled of oxide film by either a chemical method, mechanical method, or a combination of both and oiled for corrosion protection.
