Perforated Round Hole Mesh is a functional type of metal perforated sheet made by continuously punching regular round holes into metal plates using CNC punching machines combined with specialized round-hole dies. Thanks to precise punching techniques and flexible die designs, perforated round hole mesh offers a neat, attractive appearance and holds significant value for decoration, beautification, sound insulation, filtration, anti-slip, ventilation, and many other applications.
I. Production Process and Core Advantages
Material Preparation and Flattening:
Selected cold-rolled steel, hot-rolled steel, aluminum sheets, or stainless steel plates are cut and leveled to ensure material flatness.
CNC Precision Punching:
Specialized round-hole molds are installed, and the CNC system accurately controls punching position and hole size, achieving uniform hole shapes and tidy arrangements.
Deburring and Flattening:
After punching, surface burrs and hole edges are treated, and minor warping caused by punching is corrected to ensure flatness of the finished product.
Surface Treatment:
Depending on the application environment and decorative needs, surface treatments such as powder coating (polyester powder), baking paint (fluorocarbon paint), hot-dip galvanizing, cold galvanizing, or aluminum anodizing can be selected to enhance corrosion resistance and aesthetics.
Core Advantages:
Uniform Hole Distribution: High precision CNC punching ensures consistent hole sizes and center distances.
Lightweight Yet Strong: Reduces weight by 20%–60% compared to solid plates while maintaining sufficient structural strength.
High Open Area Ratio: Adjustable open area ratio (generally 10%–60%) balances breathability and load-bearing capacity.
Customizable Craftsmanship: Hole diameters range from 0.2 mm to 300 mm; sheet thickness options from 0.1 mm to 20 mm.
Eco-Friendly and Durable: Metals are recyclable; treated surfaces are weather-resistant and corrosion-proof.
II. Common Materials and Their Characteristics
Carbon Steel Perforated Mesh:
Sheet Sources: Commonly cold-rolled sheets, hot-rolled sheets, galvanized sheets, or high-manganese steel plates.
Performance Advantages: High strength, low cost, suitable for load-bearing structures and low-corrosion environments; colorful finishes achievable with powder coating or baking paint.
Aluminum Alloy Perforated Sheets:
Grade Coverage: Wide range from 1000 to 7000 series aluminum sheets.
Features: Lightweight, corrosion-resistant, excellent decorative performance; commonly treated with anodizing or powder coating, ideal for curtain walls and outdoor decorations.
Stainless Steel Perforated Mesh:
Common Materials: 201, 304, 316, 409, 430 stainless steel plates.
Functional Advantages: Excellent high-temperature resistance, corrosion resistance, and rustproof capabilities, widely used in food, pharmaceutical, chemical, marine, and humid environments.
III. Core Application Scenarios
Architectural Decoration:
Curtain wall facades, interior ceilings, partition screens, stair handrail protection — achieving both ventilation and modern decorative effects.
Acoustic Treatment:
Conference rooms, cinemas, concert halls — combined with sound-absorbing materials to significantly improve sound insulation and acoustic performance.
Ventilation and Heat Dissipation:
Server cabinets, fan guards, air conditioner covers — regular round holes ensure excellent airflow and cooling efficiency.
Anti-Slip and Protection:
Stair treads, platform gratings, industrial flooring — effectively increasing friction and ensuring safety.
Filtration and Screening:
Food production, chemical separation, liquid filtration, powder screening — customizable aperture sizes to match particle dimensions.
Municipal and Transportation:
Noise barriers, bridge protective nets, subway ventilation openings, automobile windshields — combining functionality with aesthetics.
IV. Custom Solutions and Selection Recommendations
Hole Type and Arrangement:
Supports standard straight-row and staggered layouts; non-standard custom designs are available based on drawings to achieve unique aesthetics.
Surface Treatment Selection:
For outdoor or humid environments, recommend using 304/316 stainless steel or 5-series aluminum combined with fluorocarbon coating or anodizing.
Balancing Load-Bearing and Open Area Ratio:
Higher open areas reduce load-bearing capacity; this can be reinforced by increasing sheet thickness or optimizing center distances.
Acoustic Application Enhancements:
For spaces requiring high sound insulation, back-layer with sound-absorbing cotton or polyester fiber soundproof mats to further boost noise reduction.
Maintenance and Lifespan:
Regularly clean surface dust and contaminants; intact coatings can sustain over 10 years of service life.
