MATERIALS •Structural (mild) steel (DC01, S235 ÷ S355) It’s the most cost-effective material and its surface can be done in a variety of finishes – powder paint- ing, galvanizing, hot dip galvanizing, painting, etc. •Stainless steel (AISI 304, AISI 321, AISI 316L, AISI 316Ti etc.) It guarantees a long working life and it does not corrode.It is mainly used in pharmaceutical, food processing and chemical industries production lines that are required to observe strict sanitary regulations, but they are also used in modern ar- chitecture. •Galvanized steel (DX51D + Z) It’s used for structural steel that is coated with zinc. its surface can be done in a variety of finishes such as powder paint and other coatings. It is commonly used for ventilation and air-conditioning devices, in manufacturing soundproof rooms and walls. •Aluminium (ENAW 1050) It’s used when lightweight materials are required. It has a long working life and it does not corrode. laser and punching machine It can be anodized painted with powder paint for an attractive look and a permanent gloss. •Other Metals and Materials We are able to perforate copper, brass, aluminium alloys, paper, cardboard and PVC. •Decorative metal sheets coated with PVC film They are manufactured in various finishes: Imita- tion wood, marble, stone, stainless steel, copper or brass.
