Round perforated mesh is a mesh product created by using CNC punching machines to continuously stamp uniform, round holes into metal sheets according to customer-specified molds. Thanks to its attractive hole pattern, even load distribution, and flexible processing, it is widely used in architectural decoration, acoustic noise reduction, filtration and screening, and safety protection. Depending on the base material chosen, round perforated mesh can exhibit different physical properties and visual finishes to meet varied project requirements.
Three Common Base Materials for Round Perforated Mesh
Carbon steel offers low cost, good toughness, and high load-bearing capacity, making it the most economical choice. Typical carbon steel sheet types include:
Galvanized Sheet: Coated with a layer of zinc for excellent rust resistance; ideal for outdoor or humid environments.
Cold-Rolled Sheet: High surface smoothness and flatness; produces clean, burr-free hole edges; often used for interior decoration and exhibition displays.
Hot-Rolled Sheet: Thicker and stronger, with superior impact resistance; commonly used in load-bearing support structures.
High-Manganese Steel Sheet: Extremely wear-resistant; frequently used in mining and ore-processing applications for screening and classification.
Aluminum alloy is lightweight, rust-proof, and easy to process. It can be finished with anodizing or powder coating in various colors and surface effects, making it a favorite in the decorative industry. Common aluminum alloy series include:
1000 Series: Over 99% pure aluminum; excellent conductivity and thermal performance; suitable for ventilation, heat dissipation, and shielding.
2000 Series: Copper-alloyed for high strength and fatigue resistance; often used in aerospace and specialty fields.
3000 Series: Manganese-alloyed for balanced performance and good corrosion resistance; widely used in both interior and exterior decoration.
4000 Series: Silicon-alloyed to lower melting point; suitable for welding materials and specialized processing.
5000 Series: Magnesium-alloyed for high strength and corrosion resistance; preferred in coastal or high-humidity environments.
Round Hole Mesh
Stainless steel is corrosion-resistant, heat-resistant, and durable, making it ideal for demanding environments. Popular grades include:
201 Grade: Manganese and nitrogen-stabilized for lower cost; suitable for general decorative uses.
304 Grade: Most common austenitic stainless steel; offers well-rounded corrosion resistance for both indoor and outdoor applications.
316 Grade: Adds molybdenum for superior resistance to seawater and chemical corrosion; perfect for marine engineering and chemical equipment.
409 Grade: Ferritic stainless steel with good heat resistance; often used in automotive exhaust systems.
430 Grade: Ferritic stainless steel offering moderate corrosion resistance and magnetic properties at a lower cost; used in general industrial components.
Key Considerations for Material Selection
Budget and Cost
— Carbon steel is the most economical but requires surface treatment for durability.
— Stainless steel is more expensive; choose only if the environment demands it.
— Aluminum alloy falls in between, balancing cost and performance.
Operating Environment
— For outdoor or humid settings, opt for galvanized carbon steel or stainless steel.
— In coastal or chemical environments, 316 stainless steel is recommended.
— If color and finish are critical, aluminum alloy offers the widest range of options.
Hole Diameter and Sheet Thickness
— Balance structural strength and aesthetics when specifying hole size and plate thickness.
— Typical thickness ranges from 0.5–5 mm, with hole diameters commonly between 4–50 mm.
Post-Processing Treatments
— Powder coating, painting, anodizing, or galvanizing can improve weather resistance and appearance.
— Discuss required treatments with your supplier in advance to ensure optimal results.
