Perforated galvanized steel sheet is manufactured from carbon or low carbon steel and then treated with hot galvanizing technology. Galvanizing can protect the steel for several years if applied under the right conditions. When you choose perforated galvanized steel sheet as the ornamental material for your design, we recommend that the diameter of the hole should not be less than 13 mm. This might be necessary because the perforations must be large enough so as to avoid zinc webbing across the perforations during the galvanizing process.
