Perforate is to penetrate or means creation of holes. Perforated stainless steel sheets are sheets of stainless steel which are punched with symmetrical holes and so it produces a pattern. The patterns may or may not be homogenous. They depend on the size of the hole, the way the holes were punched, the distance between the holes, the shape of the holes as well as the thickness of the sheet that was perforated.
Perforated stainless steel sheets provide strength and weldability. These sheets are corrosion resistant and are non-magnetic. The perforations are usually in parallel diagonal rows though they could also be straight in parallel vertical or horizontal rows.
These sheets are created by punching series of holes into the stainless steel plate. These holes can be round, slotted, square or even hexagonal, cane or Grecian. The perforation size, percentage of open area as well as center spacing affects the sound, light, air as well as the liquids that pass through.
These perforated stainless steel sheets are easy to handle and are very versatile. They are usually made from coil and have widths of up to 60 inches. They can be of any length. The lengths normally do not exceed 250 inches so that while shipping there are no complications or difficulties. The reason why perforated stainless steel sheets are usually sold commercially is the fact that it is easy to ship due to the flatness of the material.
These perforated stainless sheet designs have diverse patterns. In fact, there are more than 2000 different patterns which can be created on stainless steel sheets. The permutations and combinations therefore are limitless. The different patterns have 6 broad categories:
- Square patterns: These are either straight or can be staggered.
- Round patterns: These can be either straight, 40 degrees or 60 degrees
- Slot patterns: These are staggered, round, square straight and round straight patterns
- Geometric patterns: These are hexagonal, quadrilateral, pentagonal and other similar shapes
- Modern patterns: These are double checkered, round orbit, hex orbit and square orbit shaped
- Decorative patterns: These are tile shaped
As Perforated stainless steel is used commonly in architecture as sunscreens as they filter and control light. They are also used as in fills for cabinet doors and so the strength is increased but not the weight. They are used also as in fills for railings so structure is added and the mass is lowered. They are used to cover columns as they add to the beauty and aesthetic appeal. They give the architect different methods to express their creativity.
For increased ventilation and to increase efficiency, radiators are also fitted with perforated stainless steel. It is used for light fixtures as well, since it makes it more appealing visually and improves the dissemination of heat. Offices use these for receptacles or containers to hold waste and even for designs on reception desks.
This is most economical and gives high quality results. There are high speed CNC presses and these now are used to produce holes which can go up to 1,000,000 per minute. The exact requirements can be programmed and the result achieved is unique solutions which have predetermined blank areas as well as they have special margins. The spacing of the holes as well as the place locator holes can be varied as well.
The commercial establishments have the tooling which can create holes of different patterns and of widths even which are as minute as 1/64”. The level processes which are used to produce the modern and stylish perforated stainless steel sheets ensure that there are no burrs or distortions. This way the end product has good quality.
