Perforated stainless steel

Perforated metal is better known as perforated plate or sheet, and it’s a sheet of metal that has been mechanically or manually stamped. The metal ends up with pattern of holes that in some cases are decorative shapes. To manufacture this type of material, things like stainless steel, brass, aluminium and tinplate are commonly used.

Perforating metal sheets is not something new; it actually began 150 years ago. At the beginning, perforated stainless steel was used to separate coal. But in those times, the method to perforate steel was very primitive since this process was carried in a manual way. Due to this, the stainless steel started to be perforated with other techniques, for example, the application of sharp needles were perfect for the creation of the desired hole pattern.

Today, other more sophisticated methods are implemented some of which involve new technology and high-tech machines. These devices for steel perforation include pinned perforation rollers that rotate, die and press. Laser perforations have also become popular in the industry.

Applications

Perforated metals are used in many industrial processes; they seem not to be limited to anything because of their versatility.

For architectural purposes

Things like infill panels, cladding, fencing screens and metal signage are processes carried out with perforated steel sheets.

Food and beverage

Gran dryers, fruit and vegetable juice presses, baking trays and fish farming are all made with this material.

Chemical and energy

There are certain things made with perforated stainless steel, let’s name some of them: water screens, coal washing, burning tubes, centrifuges, among others.

Material development

Dying machines, textile printers, felt mills and cement slurry screens.

Automotive

Engine ventilation, flooring, silencer tubes, motorcycle silencers, and radiator grilles.

Construction

Things like ceiling noise protection, sun protection slats and sign boards are generally manufactured with perforated stainless steel.

What makes perforated stainless steel unique?

Perforated stainless steel is mostly used for decorative purposes. There are strong reasons to use this material to decorate structures: first of all, it is extremely resistant to corrosion and steel-made structures are hard to get rusty. Whether finished or not, it provides an excellent resistance. Plus, stainless steel can be finished with some coatings to increase durability. Coatings are also used to give the steel a more attractive appearance.

Besides that, perforated stainless steel is unique in sustainability and it is regarded as a re-usable resource. Companies manufacture steel with recycled material to make it last for generations. Perforated stainless steel can be recycled many times due its resistance and durability.

Countless applications

Stainless steel sheets can be used for multiple purposes, for example: sun shaded, outdoor decorations and stairs.

HVAC marker uses perforated stainless steel for air diffusers. This sturdy material is also implemented for noise control, water filtration media. Apart from that, it is an essential element in construction.

How perforating companies work

The best – reputed enterprises offer to perforate from steel to copper in different patterns that can range up to 24 gauge and 72’’ wide. They also provide custom coils and blanks. Aside from supplying, they specialise in the construction and installation of stainless steel components.

Other uses of perforated stainless steel

Thin perforated steel can be utilized for the following purposes:

  • Railways.
  • Footstools.
  • In wood industry.
  • For solar panels.
  • For racks and foundry.
  • For interior fit-outs.

Thicker perforated stainless steel sheets are used for the following purposes:

  • Food industry, trammel screens.
  • Filter press.
  • Washer plate.
  • Suspended ceilings, and partition walls.
  • Floors.
  • For the construction of agricultural equipment.
  • For interior car trims.

Companies like Sefar Metal Mesh provide a wide range of perforated metals like mild steel, and stainless steel. Perforated metals can be found in sheets of up to 3.0 mm in thickness. Hole stainless steel can be square, decorative, and with special patterns. Some businesses offer customized perforated metals as well.
