Sheet metal from stainless steel grades is classified not only by the parameters of the alloy composition, size and thickness of the sheet. The so-called punched sheet to buy , which can be used on the official website of the company supplier “ Perfomir ”, St. Petersburg) - modified by the manufacturer with through holes throughout the plane:
- Certain dimensional shape or diameter.
- In the specified sequence or frequency of application.
Strong, yet lightweight and resilient perforated sheets are used as fences and partitions in open areas. They can perfectly withstand wind loads, and are also used as a material for interior or exterior decoration.
Manufacturing technology
The technology of perforating stainless steel sheet metal provides several options, depending on the capabilities and availability of equipment from the manufacturer. Here are the main ones:
- Classic drilling - with the help of a special machine, holes are drilled according to previously prepared patterns.
- Punching punching - complex equipment is used in the form of a press, which, as it were, squeezes out (punches out) holes or through notches due to the pressure exerted on the work surface.
- Laser piercing is a rather expensive way of applying perforations of any configuration. They are usually used for processing sheets with a thickness of 12 mm.
