Finding versatile use in industry and beyond, modern perforated sheets are products characterized by very high strength and long service life. High-quality perforated metal sheet perfectly passes the test, for example, as an element of the ventilation system or as a component of lighting systems or housing industrial halls. It is also used as a decoration. In general, its primary use is in processes related to screening, filtration, purification and drying of various types of raw materials.

Its use depends mainly on what sheet perforation is involved. The cylindrical opening of the 45° system is the standard perforation. Its designation is: Rd a – t, while the relative clearance is calculated as follows: P = 1.57 x ( a2 / t2 ) x 100%.

The perforated sheets in question are manufactured from high-quality stainless steel, acid-resistant steel, heat-resistant steel, ordinary steel, aluminum, etc.

E-Invest offers perforated sheets of the best quality available in a wide range of products.
