Galvanized Round Hole Perforated Sheet

Galvanized round hole perforated sheet is made of hot-dipped galvanized sheet or electric galvanized sheet.It's an extremely cost-effective solution for corrosion protection. A layer of metallic zinc is coated on the steel sheet surface to prevent steel sheet surface from being corroded and prolong service life.which effectively blocks corrosive elements such as atmosphere and moisture. This is one of the common means of corrosion prevention in the metal industry.It is widely used in the architecture, light industries, automobile and other industries.YILIDA can provide material with different zinc coating, the hot selling zinc coating is 40g, 80g, 120g, G90 (275g).

The punching process starts with accurate mold design. We believe that the quality of the mold determines the quality of the product to a large extent. Therefore, in recent years, YILIDA has invested a lot of money in this field, which has significantly improved our mold making ability. Our factory now has thousands of sets of punching dies to meet the requirements of our customers.

After punching, there may be deformation. Therefore, we can restore the deformed perforated plate to its original flat state by using the leveling machine.
