My client told me that it was very smooth.The delivery speed is also very fast,I will receive the goods on the 7th day of the order.And the goods is inexpensive and convenient.
Ajay Parate

I have placed an oeder at this factory about FRP grating.The service is good and the grating is perfact.I'll come again.

Product Description

Customizable perforated metal sheets support ventilation, filtration, sound insulation and decoration.

Perforated metal sheet (also called punched metal plate) is a versatile metal processing material formed by stamping various hole shapes on metal plates via professional equipment. Integrating ventilation, filtration, sound insulation, protection and decoration, it boasts excellent structural stability and environmental adaptability, with customizable specifications and stable performance—widely applied in construction, industrial manufacturing, environmental protection, aerospace and other fields. This article comprehensively introduces its core attributes, specifications, applications and advantages with concise data.

1. Core Product Specifications & Customization

Perforated metal sheets offer both standardized specs and full customization to meet diverse needs, covering key dimensions and hole parameters:

Plate Size & Thickness: Conventional sizes include 1000mm×2000mm, 1250mm×2500mm, 1500mm×3000mm (ultra-long/wide customizable); thickness ranges 0.2mm–20mm (thin: 0.2mm–1.5mm for decoration/filtration; medium: 1.5mm–6mm for ventilation/protection; thick: 6mm–20mm for heavy-duty screening/support).
Hole Types: Round (universal, uniform force), square (high strength, isolation), slotted (large ventilation/drainage), hexagonal (honeycomb stability, decoration), and customized speciion/drainage), hexagonal (honeycomb stability, decoration), and customized special shapes (triangular, plum blossom, etc.).

2. Key Technical Parameters

Technical parameters directly determine product performance, with standard ranges as follows:

Key Parameter	Conventional Range	Functional Impact
Hole Diameter	0.5mm–50mm	Small holes (≤3mm) for precision filtration; large holes (≥10mm) for ventilation/heat dissipation
Hole Pitch	2mm–80mm	Denser holes (smaller pitch) = better ventilation but lower structural strength
Open Area Rate	10%–80%	Higher rate = stronger permeability/drainage but weaker load-bearing
Dimensional Tolerance	±0.1mm–±0.3mm	Small tolerance ensures high precision for matching equipment

3. Common Materials & Surface Treatments

3.1 Material Types (Performance & Applications)

Material	Core Advantages	Applicable Scenarios
304 Stainless Steel	Rust/corrosion resistance, high toughness, food-grade	Food processing, medical facilities, architectural decoration
316 Stainless Steel	Chloride/salt spray resistance, harsh environment adaptability	Marine engineering, chemical industry, coastal buildings
Galvanized Steel	Low cost, good hardness, basic rust prevention	Industrial protection, warehouse isolation, civil ventilation
Aluminum Alloy	Lightweight, ductile, easy processing, heat dissipation	Sunshade panels, ceilings, sound-absorbing panels
Carbon Steel	Ultra-high hardness, strong bearing capacity, low price	Industrial filters, heavy equipment protection, mine screening

3.2 Surface Finishing

Original Metal Color: Natural luster, wear-resistant, for industrial equipment.
Powder Coating: RAL standard colors (black, white, gray, etc.), scratch-resistant, for architectural decoration.
Anodized (Aluminum): Champagne gold, bronze, etc., no fading, high-grade decoration.
Galvanized Silver Gray: Low cost, for ordinary industrial protection.
Polished Mirror (Stainless Steel): Smooth reflective, for high-end decoration/precision accessories.

4. Main Application Fields

Construction & Decoration: Exterior wall cladding, sunshade panels, ceiling sound-absorbing panels, guardrails, stair treads.
Industrial & Mechanical Protection: Equipment covers, machine tool isolation nets, conveyor filter plates, workshop ventilation partitions.
Environmental Protection & Filtration: Air/water treatment filters, dust removal equipment, grain screening.
Civil & Commercial: Speaker grilles, lamp heat dissipation panels, supermarket shelves, decorative furniture.
Special Industries: Marine engineering, chemical anti-corrosion equipment, medical sterile equipment, mine screening.

5. Comprehensive Advantages

Compared with plastic mesh and ordinary flat metal plates, perforated metal sheets offer irreplaceable benefits: high structural strength, strong corrosion resistance, customizable performance/appearance, good ventilation/sound absorption, recyclable materials, long service life, and low maintenance cost—an eco-friendly multi-functional material.

Conclusion

Through flexible matching of materials, colors, specifications and parameters, perforated metal sheets integrate functionality and decoration. With advanced processing technology, customized products are increasingly used in modern construction, industrial production and precision manufacturing. Selecting appropriate materials and parameters based on actual needs maximizes service performance and economic value.
