Triangle Hole Perforated Metal is made of metal plates matching punching die in different sizes of aperture, forming into mesh rolls or mesh sheets with triangle holes by CNC punch pressing, cutting, slicing, leveling, grease, deburring, surface treatment and other series of processes. Compared with round hole type, there is more difficulty in processing and production for triangle hole perforated metal and It will also take a more long time. But triangle hole perforated metal possess higher tensile strength and load-bearing ability, series of open area, accurate hole size and high corrosion resistance. We produce triangle hole perforated metal in various kinds of specification by different combination of material, hole pitch and open area. And triangle hole perforated metal is more and more used in sound, noise reduction, screen filter, architectural decoration and other fields.
Material: Stainless Steel, Aluminum, Carbon Steel, Plain Steel, Galvanized Steel, etc.
| Stainless Steel | 201, 202, 304, 316, 321, 410, 430 |
| Aluminum | 5052, 5056 |
| Carbon/Plain Steel | High Carbon Steel, Mild Carbon Steel, Low Carbon Steel |
Features:
This type of perforated gratings with characteristics of lightweight, high strength, slip-resistant walking surfaces, fast and easy installation, long life span, low maintenance.
Holes Shape: Triangle Hole
Applications:
Triangle hole perforated sheets is popular materials for filter screen and architectural decoration. But triangle hole perforated metal allows for a greater open area of material and more ventilation than round hole metal, it can be mainly used for sound protection and noise reduction.
Triangle hole can be used for forming sound-absorbing color plate, micro porous sound-absorbing muffler plate, decorative ceiling board, speaker grilles.
