Decorative Perforated Sheet Metal Panels , Perforated Copper Sheets
Perforated metal, is sheet metal that has been manually or mechanically stamped or punched to create a pattern of holes, slots, or decorative shapes. Materials used to
manufacture perforated metal sheets include stainless steel, cold rolled steel,galvanized steel, aluminum, copper, Inconel, plastic, and more.
Perforated metal mesh is the marked holes in different materials
with different shapes to suit different requirements.
The process of perforating metal sheets has been practiced for over
150 years. In the late 19th century, metal screens were use as an efficient means of separating
coal. Unfortunately, the first perforators were laborers who would
manually punch individual holes into the metal sheet. This proved
to be an inefficient and inconsistent method which led to the
development of new techniques, such as perforating the metal with a
series of needles arranged in a way that would create the desired
Galvanized perofrated metal sheet: is made of hot-dipped galvanized sheet or electric galvanized
A layer of metallic zinc is coated on the steel sheet surface to
prevent steel sheet surface from being corroded and prolong service

round, square, rectangular, triangle, diamond, hexagonal, cross, slotted, fish
|hole arrangement method|
- 45°, staggered/ 60° staggered etc
|Pattern of Perforations|
- Staggered Perforations ,both Round &Square: Direction of the
stagger will normally be the short dimension of the sheet. Straight
row of hole is normally parallel to long dimension of sheet.
- Slotted Perforations: The long dimension of the slots can be
fumished with either the width or length of the sheet in most
|Spacing of Perforations|
- Spacing for large perforations will be designated be either Centers
of perforations, or by the Open Area required.
- Spacing for small perforations will ge designated by either
Centers, or Open Area, or if more practical, by the Number of
Perforated to the Square Inch
no limitation/general margin/ or as per customers' request
- Perforated Stock Size Sheet & Plates: The long sides of the
sheet will be suppiled with minimummargins. The short sides of the
sheet will have either minimum margins or no margins.
- Sheets & Plates Re-sheared after Perforating: Special margins
are available to specifications but the must carry a tolerance
within the limits of the perforating tool.
- Unfinished end pattern is standard in the industry.
- PVC coated
- Powder coated
- Fluorocarbon spraying
1) For aluminum material :
Without treatment is ok
Anodized finish (colour can be silver, blue, green, yellow,pink,
red,black, as you like)
PVDF (surface will be much more smooth, level off and glossy, it
also has a much longer life span than common treatment)
2) For iron steel material :
Galvanized : Electric galvanized, Hot-dipped galvanized
|Basic forms||sheet/panel/plate; screen; coil/ roll; tube.|
|Process||Stamping, leveling, cutting, bending, reeling, welding, shaping and
- Smooth surface
- High quality
- Easy to process and install, good sound absorption
- Durable and long service life
- Attractive appearance and wide range of thickness available
Be used to civil construction, mechanical device protection,
handcraft manufacture, grain ventilation. It also can be used in
architectural, road, bridge.
