Product Description
Perforated Metal Plate with Fine Performance and Custom Specs for Construction, Aerospace and Environmental Protection
Perforated metal sheet, also known as punched metal plate, is a universal metal processing material formed by stamping various hole shapes on metal plates through professional mechanical equipment. It integrates ventilation, filtration, sound insulation, protection and decorative functions, and has outstanding structural stability and environmental adaptability. With customizable styles and stable performance, perforated metal sheets are widely used in construction, industrial manufacturing, environmental protection, aerospace and other fields. This article systematically introduces the core characteristics of perforated metal sheets from the aspects of material types, surface colors, product specifications, key technical parameters and main applications, with detailed data analysis via tables.
1. Common Materials of Perforated Metal Sheets
Different base materials determine the service life, mechanical performance, corrosion resistance and application scenarios of perforated sheets. Each material has unique advantages and applicable environments. The mainstream materials and performance characteristics are summarized in the table below:
|
Material Type
|
Core Advantages
|
Deficiencies
|
Applicable Scenarios
|
|---|---|---|---|
|
304 Stainless Steel

|
High cost, slightly lower hardness than carbon steel
|
Food processing equipment, medical facilities, indoor and outdoor architectural decoration, daily ventilation equipment
|
|
316 Stainless Steel
|
Chloride corrosion resistant, salt spray resistant, ultra-high durability, suitable for harsh environments
|
Highest cost among conventional materials
|
Marine engineering, chemical industry, coastal building facilities, high-corrosion industrial workshops
|
|
Galvanized Steel
|
Low cost, good hardness, strong impact resistance, basic rust prevention
|
Poor corrosion resistance in humid and chemical environments, easy to oxidize after zinc layer falls off
|
Ordinary industrial protection, machinery guard plates, warehouse isolation nets, civil ventilation facilities
|
|
Aluminum Alloy
|
Light weight, good ductility, easy processing and molding, beautiful surface, good heat dissipation
|
Low structural strength, poor pressure resistance
|
Building sunshade panels, ceiling decoration, sound-absorbing panels, automobile ventilation parts
|
|
Carbon Steel
|
Ultra-high hardness, strong bearing capacity, low price, good structural stability
|
Easy to rust without surface treatment, poor corrosion resistance
|
Industrial filter screens, heavy-duty equipment protection, mine screening plates, platform pedals
|
2. Surface Colors & Finishing Treatments
The original metal color of perforated sheets is single, so surface finishing is adopted to enrich colors, while improving wear resistance, rust resistance and decorative effect. The mainstream color types and processing technologies are as follows:
- Original Metal Color: No secondary processing, retaining the natural metallic luster of stainless steel, carbon steel and aluminum. It is simple and durable, suitable for industrial equipment with no decorative requirements, and has the strongest wear resistance and stability.
- Powder Coating Colors: The most widely used decorative treatment. It can realize all RAL standard colors, including black, white, gray, blue, green, red, etc. The coating layer is firm, scratch-resistant and anti-aging, suitable for indoor and outdoor architectural decoration.
- Anodized Colors: Mainly used for aluminum alloy perforated plates, including champagne gold, bronze, black, silver and other colors. The anodized layer is integrated with the metal base, with no fading, strong oxidation resistance, and high-grade decorative effect.
- Galvanized Silver Gray: The inherent color of galvanized steel sheets, with a matte silver-gray appearance, low cost and practical, mainly used for ordinary industrial protective plates.
- Polished Mirror Color: For high-grade stainless steel plates, after mirror polishing, the surface is smooth and reflective, used for high-end decoration and precision equipment accessories.
3. Product Specifications
Perforated metal sheets have standardized conventional specifications and fully customizable sizes to meet diverse engineering and industrial needs. The specifications mainly cover plate thickness, overall size, hole shape and hole arrangement:
3.1 Conventional Plate Size & Thickness
The mainstream overall dimensions of finished perforated sheets are 1000mm×2000mm, 1250mm×2500mm, 1500mm×3000mm, and ultra-long and ultra-wide plates can be customized according to demand. The thickness range covers 0.2mm–20mm: thin plates (0.2mm–1.5mm) for decoration and filtration, medium plates (1.5mm–6mm) for ventilation and protection, thick plates (6mm–20mm) for heavy-duty screening and structural support.
3.2 Common Hole Types
- Round hole: The most universal type, uniform force, good ventilation and filtration effect
- Square hole: High structural strength, neat appearance, suitable for protective isolation
- Slotted hole: Large ventilation and drainage volume, ideal for dust removal and drainage equipment
- Hexagonal hole: Honeycomb structure, super stable, beautiful and three-dimensional, for high-end decoration
- Special-shaped hole: Customized patterns such as triangular, plum blossom and creative graphics for personalized decoration
4. Key Technical Parameters
Technical parameters are the core basis for selecting perforated metal sheets, which directly determine the ventilation capacity, filtration accuracy, structural strength and service effect of the product. The key parameters and standard ranges are analyzed in the table below:
|
Key Parameter
|
Parameter Description
|
Conventional Range
|
Functional Impact
|
|---|---|---|---|
|
Hole Diameter
|
The aperture size of a single hole
|
0.5mm – 50mm
|
Small holes (≤3mm) for precision filtration and dust prevention; large holes (≥10mm) for rapid ventilation and heat dissipation
|
|
Hole Pitch
|
Center distance between two adjacent holes
|
