.:: Microperforated sheets ::.
Special perforated sheets specific for chemical, food and mechanical purpose.
Microperforated sheets are different than any else. In these kind of sheets, diameter of holes and thickness are the same most of times (also called holes-as-thickness).
By doing perforated sheets, we must face a technological limit based on the rule "holes dia=thick": so i.e. sheets of 1 mm. thk, can be perforated with holes diameter 1 mm. up, but not with diameters lower than sheet's thk, (see "X" area). This metallurgical limit reppresents a great challenge: a few industries can bring such products into their catalogues. With s/s steel, in some cases, we did overcome this rule! (See orange points in the table). On mild steel and aluminium: ask.

Holes are placed on vertex of equilateral triangle (at angles of 60º), they can be staggered parallel on long sides or short sides. Other kind of holes have disposition at 45° or 90°.
