Carbon Steel is the most corrosive and therefore, the least expensive of the three most commonly perforated metals. Produced into coil form by roller leveling 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 are referred to as either Hot Rolled or Cold Rolled (ex. Cold Rolled Commercial Steel). The difference in processes result in products that differ 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 while it can be produced in practically any gauge, it is most 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. Zinc based coated metals (i.e. Galvanized, Galvannealed, etc.) on the other hand, are produced and supplied as such from the mill and may not completely protect the material where its carbon core is exposed during the perforating process. |
