Round Hole Perforated Sheets

Materials:

We specializes in manufacturing Round Hole Perforated Sheets in Alloys, both ferrous and non-ferrous, such as: Mild Steel, Galvanized steel, Stainless Steel, Brass, Copper, Aluminum, Plastic Sheets (P.P) and composite boards.

Hole Pattern:

There are three common methods for arranging round holes: the 45° staggered pattern, the 60° staggered pattern and the 90° straight pattern, as illustrated in the image below.

The 60° staggered arrangement stands out as the most robust and versatile option, offering exceptional durability and cost efficiency. 60° staggered & 90° straight are the angles we primarily offer, engineered with precision to ensure superior strength and outstanding value in all our products.
