steel perforated sheet, made of stainless steel, aluminum, carbon steel or another metal sheet, can be punched with round holes, oval, rectangular, square, slot, diamond, hexagonal, flower, leaf and other unique holes shapes. All can be produced according to your unique requirements. Steel perforated sheet comes in a selection of hole shapes, sizes, gauges and material types. Used for its variety of holes sizes, percentage of open area, high strength-to-weight ratio and aesthetic appeal, Perforated Metal has endless applications such as enclosures, partitions, sign panels, guards, screens, and more.

The material of the perforated sheet is mainly made of metal, iron plate, galvanized plate, stainless steel, aluminum plate are the most commonly used. The pattern of the punching net is divided according to the shape of the hole; round hole, square hole, long round hole and hexagon are standard. The perforated sheet is often used as industry decoration perforated mesh in some construction industries.

In the perforated sheet filed to follow a principle, the aperture should be greater than or equal to the thickness of the sheet metal to comply with the minimum aperture principle. The closer the hole diameter is to the thickness of the plate, the more complex the machining is and the higher the processing fee is. In some materials, the aperture can be smaller than the thickness of the plate.

Now let's talk about the arrangement of punch holes:

(1) straight line----as following picture shows)

(2) 60 ° staggered----(as following picture shows)

(3) 45 ° staggered----(as following picture shows)

(4) square hole----(as the following picture shows)

(5) long round hole (straight row)---(as following picture shows)

(6) long round hole----(as the following picture shows)

(7) hexagonal hole----(as the following picture shows)

1. Thickness: gauge 3 to 36 or as your requirement
2. Sheet size: 1ft. × 4ft., 2ft. × 4ft., 4ft. × 4ft., 4ft. × 8ft., or customized.
