Perforated Coated Steel
Perforated carbon sheet steel can be coated to make it corrosion resistant. Coatings applied after the perforating process, such as paint and powder, will completely protect the perforated metal, but coatings applied before perforating (e.g. galvanized and galvanealed) will leave the inside of the holes exposed.

|Mill-Bonderized Galvanized||Galvanized sheet with a coating of mill-bonderized phosphate for immediate painting without flaking or peeling.|
|A thin zinc coating is applied to cold rolled steel by electro-plating so as not to appreciatively affect the weight-thickness relationship. Smooth, without spangles, it is recommended as an undercoat for painted finishes. Available in Commercial and Drawing Qualities.|

Heat treated galvanized sheets, dull grey without spangles with a rough texture well suitable to painting. Can withstand temperatures up to 750°F without flaking. Less ductile than regular galvanized coating.
Other coated steels can be perforated but are often not readily available. Consult your Customer Service representative if you have a need for this.
