Perforated Metal Strip

Perforated metal strip is a type of metal material with regularly spaced holes formed by stamping on thin metal sheets. The hole diameter, spacing, and arrangement can all be customized, offering excellent permeability while retaining the metal’s strength. It is widely used in mining, electronic shielding, filtration and screening, ventilation and heat dissipation, and decorative building materials. Wanzhi Steel stocks a variety of perforated steel and aluminum strips, including round, square, and diamond-shaped holes. We offer extensive options for thickness, width, and coating customization. If you are interested, please contact us for more information.

Specification

Main advantages

1. Retains the strength of metal while achieving lightweight design, offering breathability, light transmission, ventilation, and filtration functions.

2. Wear-resistant, corrosion-resistant, and long service life. Customizable pore size and shape are supported, providing high processing flexibility.

3. Combining practicality and aesthetics, it optimizes heat dissipation and acoustics, making it suitable for industrial, architectural, and home decoration applications.

Common hole types

• Round holes: The most common and universal shape.
• Square/rectangular holes: High porosity, excellent light and air permeability.
• Rhomboid holes: High mechanical strength, good anti-slip effect.
• Hexagonal holes: High porosity, with a “honeycomb” aesthetic.
• Elongated round holes/slit holes: Precise filtration and grading, high linear flow rate.
• Special patterns: Such as fish scales, plum blossoms, crosses, etc., are mainly used for artistic decoration.

Applications of different hole types

• Round holes: Filtration and screening, such as vibrating screens, ventilation grilles, machinery protection, audio equipment, and architectural decoration.
• Square/rectangular holes: Such as heavy-duty screens for ores and coal, ventilation louvers, and grain cleaners.
• Rhombus holes: Walkways, stair treads, factory floors; anti-slip, drainage, and dust removal. Also used as decorative filters.
• Hexagonal holes: Speaker grilles, providing excellent acoustic properties; exterior wall decoration.
• Long strip round/slit holes: High-precision screening, poolside flooring, household sink panels, and drum screens.
• Special patterns: Railings and screens in science museums, studios, galleries, etc.; art installations; capable of creating dynamic light and shadow effects.

Application of different materials

• Perforated stainless steel strip: 304 and 316 grades are used in food processing, medical equipment, chemical equipment, coastal construction, and high-humidity indoor environments.
• Perforated aluminum strip: Applications with weight requirements. Vehicle interiors, exterior wall decoration, electronic equipment housings, and home furnishings.
• Perforated galvanized steel strip: Outdoor building protection, ventilation ducts, electrical cabinets, light boxes, and traffic platform designs.

Core technology

The primary process for perforated metal strips is stamping. It is manufactured through CNC stamping and laser cutting. Wanzhi Steel verifies burrs, flatness, and hole diameter tolerances. For the perforated metal strips, we offer surface treatments such as galvanizing, anodizing, painting, and brushing/polishing to achieve a wide variety of products.
