Perforated metal mesh usually used galvanized steel, stainless steel, copper steel, aluminum steel, nickel steel and alloy steel as material. We have advanced CNC equipment, our products made by model. Our products have the advantage of high precision, small error and good quality. The punch diameter from 0.3mm to 100mm, and made thickness equal diameter, namely the thickness 0.5mm can punch diameter 0.5mm.

Process of Perforated Metal:

• Hot-dipped galvanized perforated metal. Immersed thin steel plate into the zinc bath, adhesion to the surface layer of zinc. Currently the main use is production of continuous galvanizing process, that is a continuous roll of steel immersed in melted zinc plating bath is made with galvanized steel.

• Electro galvanized perforated metal. This kind of perforated metal have a good ability of processed. However, thinner coatings, corrosion resistance than hot-dip galvanized perforated metal sheet.

Stainless steel perforated metal

Stainless Steel Perforated Metal is made of high quality Stainless Steel sheet/coil after being perforated on the digital control machines. Stainless Steel Perforated Metal is used in a variety of corrosive atmospheres; its long life pays back its seemingly high cost.

Specification: The thickness of coil from 0.2mm to 0.7mm, the length from 1m to 20m, the diameter from 2mm to 20mm. The thickness of plate from 0.3mm to 3mm, the minimum aperture is 0.6mm.

Aluminum perforated metal

Aluminum Perforated Metal is made of high quality aluminum sheet/coil after being perforated on the digital control perforated machines. Aluminum perforated metal has the features of good strength-to-weight ratio, wide range of open area percentages, accurate hole size, available in corrosion resistant materials, available in lightweight material and suitable for decorative applications.

Hole shape: Round hole, square hole, long round hole, triangle hole, scale hole, diamond hole, oval hole, hexagonal hole, slot hole, and so on.

The application of perforated metal:

• Used for environmental noise control barriers, such as, highway, railway, subway, etc.
• As sound-absorbing material of the building ceiling and wall.
• Used for building stairs, balconies, beautifully decorated plate of green furniture.
• Protective cover for the machinery and equipment, ornate speaker enclosures.
• Used as kitchenware, such as, stainless steel fruit basket, food cover, fruit tray, etc.
• Shopping network with shelves, decorative exhibition units.
• Grain storage within the ventilation network, soccer turf seepage water treatment network, and so on.

GNEE Steel Grating Application

Steel grating are designed and manufactured for various industrial and civil constructions in city road, gardens, yard, airport, railway and industrial engineering.

• Hot dip galvanized steel grating is the best choice for steel platforms in airports. Grating with 30 × 3 mm thick load bearing bars with a pitch of 30 mm and traverse bars at 50 mm or 100 mm is the suitable one.
• Steel grating, with robust design and spanning abilities, is very strong and safe for the support of floors and elevated walkway. It can be used for ceiling, interior decoration, platform aisle, ventilation windows, (Wells), advertising plaque and other construction.
• Widely used in the petrochemical industry, power plants, waterworks, sewage treatment plants, municipal works, sanitation projects in areas such as platforms, corridors, bridge, ditch cover, covers, ladders, fences, rails, and so on.
