Carbon Steel

Carbon steel is the most corrosive and least expensive of the three most commonly perforated metals. Produced into coil form by roller leveling it to a desired thickness, either once while the steel is still hot or again after it has cooled, each of the carbon steel types listed below is referred to as either Hot Rolled or Cold Rolled e.g., Cold Rolled Commercial Steel. The difference in processes results in products that vary in terms of cost, quality, and mechanical properties. In short, Hot Rolled is typically less expensive and produced in thicker gauges 7-16, whereas Cold Rolled provides tighter tolerances, better surface finishes, and can be produced in practically any guage. It is most often readily available in thinner gauges 14-28.

Because carbon steel is susceptible to corrosion, it is typically used in either unexposed applications or protected with a coating. Coatings such as paint and powder are applied after perforating and completely protect the material. However, zinc-based coated metals (i.e., Galvanized, Galvannealed, etc.) are produced and supplied as such from the mill and may not completely protect the material at its carbon core when exposed during the perforating process.

Commonly Perforated Carbon Steel Types

NOTE: Unless specified by the customer, Diamond Manufacturing Company reserves 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, Diamond Manufacturing Company will use Commercial Steel which is the most commonly perforated carbon steel for pricing and production.
