Common Specifications
Perforated Material: galvanized sheet, cold plate, stainless steel sheet, aluminum sheet, aluminum-magnesium alloy sheet.
Perforated Hole type: round hole, oval hole, square hole, diamond hole, triangular hole, cross hole, hexagonal hole, plum blossom hole, fish scale hole, long waist hole and other holes can be customized.Round Hole vs. Slot Hole Perforated Metal
Round holes are the standard choice for perforated metal sheets, offering excellent structural strength, uniform stress distribution, and reliable performance in filtration, screening, ventilation, and noise control. They provide consistent open area, precise particle separation, and a clean, versatile appearance suitable for most industrial and architectural uses.Slot holes feature elongated openings that allow higher airflow, better drainage, and greater light penetration. They create a modern linear aesthetic for facades and improve efficiency in bulk screening. However, they offer slightly lower rigidity and are less ideal for fine filtration. The selection depends on required open area, flow rate, filtration precision, and design style.Perforated Specifications

Application Area
1. Filtration
Perforated metal sheets act as robust filtration media in liquid and gas processing systems. Their precisely sized holes effectively separate solid particles, debris, and contaminants from fluids, making them ideal for strainers, filter housings, water treatment components, oil and gas purification, and industrial particle separation. They offer high mechanical strength, easy cleaning, and long service life compared to mesh or fabric filters.2. Noise control
Perforated metal is widely used for acoustic management by absorbing and dissipating sound waves. When combined with sound‑absorbing materials, it reduces reverberation and airborne noise in machinery enclosures, HVAC systems, industrial facilities, stadiums, and architectural spaces. It provides both effective noise reduction and structural durability in high‑noise environments.3. Architectural facade
As a modern decorative and functional building material, perforated metal sheets enhance architectural facades with aesthetic patterns, light transmission, and shadow effects. They support customized hole shapes, spacing, and finishes to create unique exterior designs while offering sun shading, ventilation, and weather resistance. They are widely applied in commercial buildings, stadiums, airports, and urban landscape structures.4. Ventilation
Perforated metal ensures efficient and controlled airflow in mechanical and natural ventilation systems. It is used in ventilation grilles, cabinet vents, electronic equipment enclosures, HVAC outlets, and building air circulation components. The uniform perforations maintain airflow stability while blocking dust, insects, and foreign objects, balancing ventilation and protection.5. Screening
Perforated metal sheets serve as durable screening solutions for sorting, sizing, and protecting materials in industrial and civil scenarios. They are used in security screens, machine guards, particle classifying screens, safety barriers, window and door screens, and quarry or construction screening. High rigidity and wear resistance make them suitable for heavy‑duty screening and long‑term protective use. -
