Abstract
A process for producing a galvanized perforated steel sheet material is described. A fully processed, unfinished sheet steel material is perforated to provide an area or areas of holes therein. The sheet material is then temper rolled to force any burrs formed during the perforation process back into the web of the material. The perforated sheet material is then galvanized. The galvanized perforated sheet material may then be roll painted without damage to the painting rolls.
