Round Hole Perforated Metal

Round hole perforated metal is the most common and widely used type, and its visual effect is remarkable.

Generally, the perforated hole diameter should not be smaller than material thickness.

And the space between two neighbouring holes should be equal to or larger than the material thickness. Or the material structure will not be stable or strong.

Material: Low carbon steel, stainless steel, galvanized, aluminum, Brass and etc.
Weaving: Punching and etching, the thickness less than 0.5mm, need to be etched
Feature: Winding-resisting, aging-resisting, corrosion resisting
Hole shape: Round, long round, slot, oval, square, diamond, triangle, scale, hexangular and etc.
Thickness: 0.5mm-4mm, etc.

We can provide different sizes and shapes of perforated metal mesh according to customer requirements.

Round hole has three arrangement patterns: 45° staggered pattern, 60° staggered pattern and, straight pattern (90° staggered pattern). Among the three patterns, 60° staggered pattern is the most widely used type. It provides the largest open area to maintain material strength.
