Perforated Metal Screen/sheet
Shanghai Spring Industrial Corporation can supply perforated metals in sheets or coils, in stainless
steel, brass, iron and other metals. Perforated metal products can
be made into screens, filters, baskets, trash cans, tubing, light
fixtures, vents, audio speaker covers and patio furniture. Like
expanded metals, perforated metals are also used for filtration,
reinforcement and decoration in the form of sheets, gratings,
flooring, angle beads, etc.
General Metal Sheets Sizes for Perforating:
Standard perforated metal sheets we supply are size 1000 x2000 mm,
thicknesses from 0,3 mm up to 10 mm and perforation from 0,3 mm up
to 100 mm. Our maximum material thickness, which we can perforate
up to, is 25mm, the most common thickness range for balustrade
infill, cladding panels etc. is between 1.5mm and 3.0mm although
heavier specifications do away with having to frame the sheets with
something like edging profile which we also supply.
The maximum width we can perforate up to is 2mt, the preferred
maximum is 1.5mt.
The maximum length we can perforate up to is 6mt, the preferred
maximum is 4mt.
General Perforation Openings:
Perforation range: round, square and rectangular holes.
We perforate a wide range of round, square, slotted, decorative and
even odd shaped perforations on special request. Percentage open
area, the most common percentage open area is between 30% and 50%
although more extreme open areas are available depending on the
perforation. Some times the percentage open area has to be kept
lower for increased strength and flatness of the sheet especially
when galvanising.
Perforated Metal Sheet Materials:
The most common material types are mild steel, Pre-galvanised mild
steel, stainless steel, aluminium, brass and some types of
plastics.
Perforated metal is used in many applications such balustrade
infill, acoustics, security screens, air-condition units, radiator
covers, screening, reinforcement and decoration in the form of
sheets, gratings, flooring, angle beads, etc.
