The technical parameters that characterize perforated sheets predispose them to a variety of applications in many industrial and economic sectors, with the type of perforation of the sheet being of no small importance. Today, perforated sheets are produced from a variety of materials, including:
- from steel – ordinary, wear-resistant, stainless, heat-resistant, acid-resistant,
- from non-ferrous metals – such as aluminum.
Extended holes Passing arrangement is a popular perforation involving the execution of holes in both horizontal and vertical versions. Therefore, two specifications are specified in this case:
- horizontal holes:
– designation: Lv a x b – t x t1,
– relative clearance for a < b: P = 2 x [( a x b ) – (0.215 x a2)] / (t x t1) x 100%, - vertical openings:
– designation: Rv a – t,
– relative clearance: P = 0.91 x ( a2 / t2 ) x 100%.
E-Invest offers customers perforated sheets that meet current technical and quality standards. Each of our perforated sheets is a high-end product.
Designation:
Lv a x b – t x t1
Relative clearance for a < b:
P = 2 x [( a x b ) – (0.215 x a2)] / (t x t1) x 100%
The first dimension in the name indicates which dimension of the mesh is parallel to the longer side of the perforated sheet.
