Perforated metal sheets manufactured from steel are cheap and versatile
The material is easily deformable and is therefore often used in sieve and recycling technology as a half-shell or sieve drum.
Since there are different levels of strength in the steel grades, longer service lives of the sieves are also possible here.
Railing fillings made of perforated steel sheets are often used as post-galvanized or powder-coated variants for home and apartment renovations, but also as burglary protection against cellar windows or ventilation panels.
