High-quality perforated – or in other words, perforated – sheets play an extremely important role in industry. Their properties make them indispensable products in various industries, while the fact that perforated sheets differ from one another in dimensions and in the arrangement and shape of the meshes allows them to be precisely adapted to specific needs.

Cylindrical openings arranged 60° is a very popular perforation denoted as Rv a – t. relative clearance is calculated in this case as follows: P = 0.91 x ( a2 / t2 ) x 100%. This type of punched sheet is used, among other things, in the construction industry, in the mining industry, and is also used in a wide range of equipment, such as agricultural machinery and baking equipment. It is produced, among others, from aluminum and from many varieties of steel: stainless, acid-resistant, ordinary, heat-resistant, etc.

E-Invest, as a proven and experienced manufacturer, offers high-end perforated panels, made in accordance with current technical and quality standards.
