Type overview

Commonly Perforated Mild Steel (Carbon Steel) Types:
Commercial Steel (HR, CR, GALVANISED, ALUMINISED )

Low cost steel that has good drawing, forming, and welding qualities, moderate strength, but is subject to strains, fluting, and fracture due to ageing. To reduce the affects caused by ageing, drawing steel is recommended.
Drawing Steel (HR, CR)

Steel with a greater degree of ductility and uniformity of properties than seen in Commercial Steel providing improved performance during manufacturing.
Forming Steel (GALV)

A steel with lower strength and higher elongation than Commercial Steel. Recommended when stresses from forming either crack or weaken Commercial Steel.
Unless specified by the customer, perforating companies reserve the right to quote and/or supply either Hot Rolled or Cold Rolled Steel - depending on what is available, economical, and commonly perforated given the size and application.
If a steel type is not specified, Commercial Steel will be used for pricing and production.
