Enormity of applications ...

Perforated sheets reflect a very wide range of applications. They surround us in everyday life almost everywhere, making easier to carry out daily activities or tasks. You may ask how and where? - some examples below:

In your home / apartment / office / work:

RTV equipment - virtually each of them contains perforated part that optimizes the cooling process during operation : computers, decoders, amplifiers or TV.

Household appliances - cooker hoods, ovens, ventilation devices are the items that need appropriate perforated components without which it would be impossible to use them safely.

Decorative elements in architecture, creating the interior or exterior design of buildings you rest or work in : facades, elevations, suspended ceilings, partition walls, balustrades, covers. Perforated metal is a perfect proposal for these applications.

A very first but still current usage in heavy industry, mining and shipbuilding, i.e. as industrial screens, filters, technical sieves. Parts of machines and devices with its core made of perforated sheets (sorting lines, separators, screening drums).

List of main applications:

Architecture

Automotive

Industrial processing (petrochemical, pharmacy)

Machine industry

Food industry

Mining industry

Recycling

Basic information and technical parameters:

Material – mild steel, galvanized steel, aluminum, stainless steel, acid, brass, copper.

Sheet thickness - from 0.5 to 10 mm

Dimensions: standard 1000x2000; 1250x2500; 1500x3000 mm or customized.

Margins without perforation around the plate:

As a standard, perforated sheets are produced with margins without holes around the perimeter of the sheet.

Size (width of margins) is to be determined (5-35 mm depends on the dimensions of the sheets and the type of perforation). It is possible to make sheets in accordance with the customer's suggestion (drawing), adjusting all values ​​to the individual needs (e.g. cutting sheets through the holes, without margins). Optionally, it is possible to design several sectors on the sheet metal with additional transverse, middle and longitudinal margins.

* Due to the punching technology, the holes on back side of sheet metal have a slightly larger diameter.

* Beginning and the end of the perforated area: for the small holes and high value of clearance, it might be necessary to remove every second hole at the beginning and the end of the perforated field  (graphics below).

​

Hole's shapes:

Round :

Rg -straight centers, Rv - staggered centers 60 degrees; Rd -staggered centers 45 degrees.

Square:

Qg - straight centers, Qv - staggered centers, Qd - caro arrangement

Longitudinal:

Lg - straight centers , Lv - stagerred side centers

Rectangular:

Pg - straight centers, Pv - stagerred side centers

Hexagonal:

Sv - stagerred centers
