Holes between 3-8 mm, pitch 5-12 mm, variable density
This type of metal perforation is carried out by drilling holes with a diameter between 3 and 8 mm with a pitch between 5 and 12 mm; they can be carried out at different distances from each other in order to obtain a total area with denser and smaller or less dense and larger holes.
