perforated metal sheet

perforated metal sheet is a plate-like structure product that is made by punching holes of different shapes on the dutcherial to meet different needs.

1. Definition and characteristics

perforated metal sheet is a plate-like structure with regular holes made of plates of different dutcherials through stamping technology. It uses continuous punching of coils to process a larger range of sizes. The processing speed of perforated metal sheet is fast, less cutting waste is generated, and the dutcherial utilization rate is high, so the processing cost is low. However, since it is processed by a punching machine, the mesh may have burrs and bumps, and it is difficult for the hole wall to reach verticality.

2. Specifications and parameters

The specifications and parameters of perforated metal sheet vary depending on the dutcherial and demand. Taking common metal sheets as an example, the thickness of the coil is usually between 0.2mm and 1mm, and the length can reach 20m. The thickness range of sheet is wider, ranging from 0.2mm to 20mm, and the width and length are customized according to customer needs, but generally not more than 1.5m×5m. The size of the aperture is also determined according to demand, with a small size of only 0.5mm and a large size of up to 200mm.

3. Punching methods and hole types

There are many different punching methods for perforated metal sheet, including but not limited to the following:

Continuous punching in the same direction: using a rectangular perforated metal sheet mold to partially overlap processing, you can process long holes, trimming, etc.

Continuous forming: a forming method that forms a larger size than the perforated metal sheet mold, such as large-size blinds, rolling ribs, rolling steps, etc.

Erosion: a processing method that uses a small round mold to continuously punch arcs with a smaller step distance.

Multi-directional continuous punching: a processing method that uses a small perforated metal sheet mold to process large holes.

Single forming: a processing method that shallowly draws and forms according to the shape of the mold.

Single punching: punching is completed in a single time, including linear distribution, arc distribution, circumferential distribution, and grid hole punching.

Array forming: a processing method for processing multiple identical or different workpieces on a large plate.

The perforated metal sheet hole types include round, square, oval, diamond, hexagonal, cross, triangle, plum blossom, long waist, fish scale raised holes, etc. Different hole types are used in different application industries.

4. Application fields

Due to its unique structure and excellent performance, perforated metal sheet has a wide range of applications in many fields:

Transportation and municipal facilities: It can be used as an environmental noise control barrier in transportation and municipal facilities such as highways, railways, subways, etc. that pass through urban areas.

Construction field: It can be used as a sound-absorbing board for sound insulation and noise reduction of noise sources such as building walls, generator rooms, and factory buildings.

Mechanical equipment: It can be used for protective covers and speaker mesh covers of mechanical equipment.

Screening and filtration: It can be used for grinding screens, mine screens, I-shaped screens, etc. for grain, feed, and mines, as well as filter media for air, liquids, and solids.

Kitchen equipment: It can be used for kitchen utensils such as stainless steel fruit baskets, food covers, and fruit plates.

Commercial facilities: It can be used for shelf nets in shopping malls, decorative exhibition stands, etc.

Other fields: It can also be used for ventilation and air permeability nets in grain depots, water seepage and water filtration nets for football field lawns, etc.

perforated metal sheet is a mesh product with multiple excellent properties and a wide range of applications. When selecting and using it, it should be customized and installed according to specific needs to ensure its best filtering effect and service life.
