Powder Coating Perforated Stainless Pipe Optional Galvanized For Petrol Textile

Powder Coating Perforated Stainless Pipe Optional Galvanized For Petrol Textile

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.

Commonly Perforated Carbon Steel Types
Commercial Steel (HR, CR, GALV) A low cost steel that has good drawing, forming, and welding qualities, moderate strength, but is subject to strains, fluting, and breaks due to aging. To reduce the affects caused by aging, Drawing Steel is recommended.
