Multi Functional Perforated Metal Plate Designed for Ventilation Sound Insulation and Anti Slip Applications with Custom Hole Patterns
Also known as Perforated Sheet, Perforated Metal Mesh is a premium metal material produced by punching a variety of regular and irregular holes on metal panels via high-precision stamping equipment. Balancing robust structural strength and versatile performance, it suits a broad range of industrial applications. Meanwhile, full customization is available in specifications, raw materials, colors and surface finishes to perfectly adapt to diverse working and environmental conditions.
I. Core Product Features
Stable Structural Performance
Adopting integral one-piece stamping technology, the evenly distributed openings will not compromise the overall structure of the metal sheet. The product delivers outstanding compression and tensile resistance, featuring great deformation and fracture resistance, as well as an extended service lifespan.
Diversified Functional Performance
It combines multiple practical properties, including ventilation, daylighting, filtration, sound insulation, anti-slip and decorative effects. The functional performance can be flexibly adjusted by changing hole specifications to fit diversified application demands.
Powerful Customization Flexibility
Raw materials, hole diameter, hole shape, panel dimensions and colors can all be tailored on request. It perfectly meets personalized demands across industrial construction, interior and exterior decoration and other sectors.
Simple Installation & Low Maintenance
Featuring lightweight and streamlined structure, the plate can be freely cut, spliced and installed on site. No complicated daily maintenance is required, and the smooth surface allows easy cleaning, effectively lowering long-term operating costs.
II. Core Technical Specifications
Panel Size
Sheet thickness: 0.3mm to 12mm (common range: 0.5mm–5mm); width: 300mm–1500mm; length: 1000mm–6000mm. Custom cutting and special dimensional processing are available upon request.
Hole & Pitch Specifications
Hole diameter: 0.5mm–100mm (conventional size: 1mm–20mm); center hole pitch: 1mm–150mm. Hole density is customizable, with three mainstream arrangement modes: straight row, widely used staggered row, and diagonal row.
Hole Shapes
Regular options include round, square, rectangular, slotted and hexagonal holes; customized decorative shapes cover diamond, plum blossom, five-pointed star and special irregular holes. Round holes remain the most popular option with the widest compatibility.
Open Area Ratio
Adjustable from 5% to 60% based on needs. The open area directly determines ventilation, daylighting and filtration efficiency. A higher open area offers better air permeability and light transmission, while a lower ratio ensures stronger structural stability.
Dimensional Tolerance
Sheet thickness tolerance: ±0.05mm to ±0.2mm; hole diameter tolerance: ±0.03mm to ±0.1mm; overall dimension tolerance: ±1mm to ±3mm. Tolerance accuracy can be upgraded for high-precision projects.
III. Material Selection
Multiple material options are available according to on-site corrosion, temperature and load-bearing requirements:
- Stainless Steel (Most Widely Used):304, 316 and 316L grades. Excellent in corrosion resistance, high temperature resistance and rust prevention, ideal for outdoor, humid, acid and alkali environments such as chemical, marine and food processing industries.
- Carbon Steel (Mild Steel):Q235 grade. Cost-effective with high mechanical strength, suitable for indoor dry areas and non-load-bearing occasions. Surface treatment can be added to enhance its anti-corrosion capability.
- Galvanized Steel:Available in hot-dip galvanized and electro-galvanized types. The galvanized coating provides better rust protection than ordinary carbon steel, suitable for outdoor fences, municipal facilities and outdoor projects.
- Aluminum Sheet:Lightweight, ductile, corrosion-resistant and aesthetically pleasing. Perfect for scenarios requiring light weight and high appearance, such as decoration, aerospace and automotive industries.
- Copper Sheet:Outstanding in electrical conductivity, thermal conductivity and corrosion resistance, applicable to electronic equipment, chemical engineering and high-grade decorative projects.
IV. Color & Surface Finish
The final color of perforated metal plate depends on surface treatment, with both standard and custom colors available to satisfy functional and decorative needs:
Regular Colors
Silver (original stainless steel / aluminum color), galvanized gray, black, white, grayish blue and red (powder coating finishes), widely used in general industrial and construction projects.
Custom Colors
Custom powder coating, anodizing and spraying colors can be provided per customers’ Pantone codes or color samples, matching the overall design of building facades, interior decoration and customized projects.
V. Application Scope
Thanks to multi-functional advantages, perforated metal plates are widely applied in industry, construction, decoration, environmental protection and other fields:
- Construction Industry:Building facades, ceiling panels, partition walls, sunshade panels, sound insulation walls, stair railings and exterior wall decoration, improving both building beauty and practicality.
- Industrial Industry:Machine protective covers, filter plates, sieve panels, ventilation grilles, noise reduction equipment and conveyor screens, serving chemical, pharmaceutical, food, metallurgy and other industries.
- Decoration Industry:Indoor ceiling and wall decoration, furniture accessories, exhibition hall decoration and advertising sign panels, creating unique visual effects.
- Environmental Protection & Municipal Engineering:Sewage treatment filters, waste screening, municipal green fences, road sound barriers and public facility decoration.
- Other Fields:Automotive accessories, aerospace parts, electrical enclosures and household appliance filters, meeting special functional requirements of various industries.
