Perforated metal sheets punched in mild steel, galvanised, aluminium, stainless steel and special alloys. Stainless Steel perforated metals are used extensively in the engineering, food processing, building, agricultural, nuclear power and petrochemical industries and many others. Perforated materials are used in a number of different applications for a variety of reasons. Used mostlyas screens, filters, shields, and guards, perforated materials can control the passage of air, liquid, light, solids, heat, electromagnetic waves, and sound waves. Perforated Metal Products are widely used in every industry. Perforated metal mesh has a greater, more predictable (and accurate) load bearing capacitythan expanded metal or wire mesh. Perforated Metal Sheet can be made into a number of hole types, patterns and thickness.
