Used in various industrial and economic sectors, perforated sheets differ from one another in many respects. The most important criterion for their division is the holes used in them and their layout. A very popular type of perforation is cylindrical holes straight arrangement. This type of sheet perforation is given the designation Rg a – t, and its relative clearance is calculated as follows: P = 0.785 x ( a2 / t2 ) x 100%.
Dimensions, spacing and mesh size tolerances are made by us in accordance with the applicable standards. Each perforated sheet with cylindrical meshes in a straight arrangement included in our product range is a high-end product with very high usability. The diameters of the holes are carefully matched to the thickness of the sheet, which increases its functionality and technical qualities.
E-Invest offers customers perforated plates made of excellent quality materials, such as:
- from acid-resistant steel,
- of ordinary steel,
- of stainless steel,
- of aluminum.
