A special category of our company’s product range is perforated metal sheets available in many variants. Depending on the sheet perforation used, the usable qualities of the product change. Square openings straight arrangement is a frequently used sheet perforation denoted by the symbol Qg a – t, where the relative clearance is calculated using the following formula: P = ( a2 / t2 ) x 100%.
Modern square hole punched sheets are produced from ordinary steel, wear-resistant steel, stainless steel, acid-resistant steel and heat-resistant steel, as well as non-ferrous metals such as aluminum. It is ideally suited for processing by cutting, bending, punching, rolling, as well as welding, welding, powder coating and galvanizing.
