304L ASTM A240 Stainless Steel Perforated Sheet Metal For 0.3mm - 120mm Thickness

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

In the perforated sheet filed to follow a principle, the aperture should be greater than or equal to the thickness of the sheet metal that is to comply with the minimum aperture principle.The closer the hole diameter is to the thickness of the plate, the more difficult 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 show)

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

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

(4) square hole----(as following picture show)

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

(6) long round hole----(as following picture show)

(7) hexagonal hole----(as following picture show)
