Welcome to Lamina Perforated Sheet Factory!

We are a professional manufacturer of perforated metals. We mainly provide galvanized perforated sheet, perforated aluminum and stainless steel perforated metal sheets. We provide a variety of hole patterns and a complete range. You are welcome to inquire.

Lamina perforated metal sheets find extensive uses in making of noise barrier panel, acoustic ceiling sheet, grating panels, filter elements, strainers, diamond perforated sheet, round hole perforated metal and various decorative metal cladding panels.

Popular patterns of perforation come in Triangle, Five-star, Hexagon, Cloverleaf, Diamond, Square, Dimple and decorative designs. The metal sheets are made with flat plates or anti slippery raised patterns.

The raised checkered or dimpled metal plates are popularly used in safety floor and treading uses.

We make perforated metals out aluminum, stainless steel, galvanized steel, cold-rolled carbon steel, copper, brass and other metals. Perforated sheets can be punched from metal plates and coils providing options of margins and blank areas, along with full perforation styles. A common way to produce perforated metal is using coils. This method provides great flexibility in both design and handling. Perforated coils can be produced faster than perforating sheets.

Standard perforated metal sheets we supply are size 1000 x2000 mm, thicknesses from 0,3 mm up to 10 mm and perforation from 0,3 mm up to 100 mm. Perforation range: round, square and rectangular holes and much more.
Usually holes diameter can not be lower than thickness. Usually the round holes layout is at 60°. Squared and rectangular holes, instead, are aligned.

Three Featured Products Taking Advantages of Unique Properties of Perforated Metal:

Architectural Perforated Mesh: Perforated metals have light weight and multiple choice of aesthetic patterns, can be easily adapted into forms to meet various designs. Widely used as facade screen, suspension acoustic ceiling panels, metal partitions and decorative curtains, louver shutters and sunshade screen, building ventilation screen in modern buildings and architectures like Shopping Mall, Museum, Hotels.

Diamond hole, round hole and slot perforation are popularly used in cladding panels for outdoor decoration.

Perforated metal sheets with round hole perforation are popularly used in mesh ceilings panels. Standard metal sheets: 100 x 100, 300 x 300, 600 x 600, 300 x 600, 600 x 1200mm. With light weight, perforated aluminum tiles are ideal for indoor suspension acoustic absorption panels.

Checkered Metal Floor Plates: Taking advantage of checkered metals with raised anti-slippery texture, this kind of metal sheet is popularly used in various industrial flooring panels.

Perforated Filters and Tubes: Taking advantage of the precise hole and the strength of the one-unit metal material processing, perforated sheet is welded into filter pipes or filter support tube to control the passing liquid.

Major Production Steps:

• First, make product mould based on customer's requirements: punching process begins with precise mold design, mold quality largely determines the quality of the products.
• Secondly, metal punching. Lamina has advanced numerical control press equipment, and can punch the metal plate with precise hole, margins and arrangement.
• Third step is edge trimming. If the production process of plate edge is beyond the tolerance range of your requirements, our skilled technical personnel can according to your request help you eliminate redundant edges.
• Fourth step is metal plate leveling. Leveling machine can help us restore its original level which are out of shape in the process of punching.
• Fifth, cleaning. To remove traces of its surface and make the perforatedd metal mesh clean.
