The perforated metal mesh sheet is a commodity made from sheet steel that has been punched out of circular holes by a drill or other designs. To maximize the number of openings, these holes may be arranged in straight rows or spaced. A boundary along the circumference of the board, where no holes are punched, provides stability to the sheet. The metal that has been stripped from the holes may be recycled, although this raises the price of the component. The bigger the hole size or the number of holes, the higher the scrap value, and hence the larger the prices.
Finishes and plating: Electro-polishing makes the surface of stainless steel more uniform and visually pleasing. Powder coating offers both an additional layer of protection and the ability to incorporate various colours into a durable final product.
Type of metal: Aluminium, stainless steel and galvanised steel are common choices when selecting perforated metal sheets for architectural projects. Most common finish is powder coated for colour consistencies, and you can get the same or similar warranty on coating these days without the headaches. Anodised aluminium has increased resistance to corrosion due to a thick oxide layer formed on its surface as part of the anodising process. Improving the metal in this way also allows for other benefits, such as colouring the metal. Stainless steel is a steel alloy designed to inhibit the development and spread of rust through the addition of chromium during the steelmaking process. Galvanised steel has a zinc coating that also inhibits rust.
We start with a coil of sheet metal in the desired gauge of the product we're making. There are a few different methodologies for different products, however for standard products the coil is fed into one of the machines. The machine's rollers pull the metal through, and the holes are punched by needles mounted on a rotating cylinder as the sheet metal moves through the machine.
For more specialised products, the whole sheet would be loaded into a turret punch, where the pattern is programmed in. This way the machines can punch the right configuration of different sized holes to present the larger image. The turret punch allows multiple needle profiles and sizes to be swapped into the punching position, so it's perfect for jobs that require unconventional patterns or greater detail.
Privacy：Positioned correctly, perforated metal can make it easy for those inside a structure to see out while still providing a sense of privacy from passers-by and the general public seeing in. If your project team needs to consider safety as it relates to visibility but doesn’t want to sacrifice aesthetics, perforated metal may be the perfect choice.
Regulation of natural light: When used in front of windows and similarly transparent architectural elements, perforated metal can reduce overall exposure to sunlight, which can also provide benefits in terms of costs and temperature regulation, while still allowing some natural light to enter the structure.
Ventilation and airflow: Perforated metal allows air to flow freely through it when used as an interior wall or external facade, as long as it isn’t positioned directly over another layer of material.
Our engineering team are always looking for ways to improve the range, and this involves some experimentation. Trying out new methods, experimenting with tensile strengths and folding/trimming techniques to get the best possible product out of the design and manufacturing teams.
