Perforated Sheet Metal Panels with Round, Square, Slotted, and Hexagonal Hole

ZhongPu Wire Mesh Co., Ltd. offers Perforated Sheet products engineered for filtration, screening, ventilation, noise control, safety guarding, and architectural decoration across industrial and construction sectors. Available varieties include round hole, square hole, slotted, hexagonal, and decorative perforation patterns, manufactured in carbon steel, galvanized steel, stainless steel (304/316), aluminum, and other metal alloys. Standard sheets or custom-cut panels are available with adjustable thickness, hole diameter, pitch, and open area.

Hole Shape

• Round Hole Perforated Sheet: Hole diameters range from 0.5–50 mm, with straight or staggered pitch from 1.5–100 mm. Sheet thickness typically ranges from 0.3–12 mm.
• Square Hole Perforated Sheet: Square hole perforated sheets use uniform apertures, generally 1–50 mm, arranged in straight-line patterns. Standard sheet thickness ranges from 0.5–10 mm.
• Slotted Perforated Sheet: Slotted perforated sheets are defined by slot width and length, commonly 1–20 mm wide and 5–100 mm long. Sheet thickness typically ranges from 0.8–12 mm.
• Hexagonal Perforated Sheet: Hexagonal perforated sheets feature honeycomb-style openings, usually 5–50 mm across flats. Typical thickness ranges from 0.6–6 mm.
• Decorative Perforated Sheet: Decorative perforated sheets provide custom hole shapes, sizes, and patterns. Hole dimensions, pitch, and sheet size are customizable, with thickness typically 0.8–6 mm.

Material

• Carbon Steel Perforated Sheet: used for screening, guarding, and mechanical protection in dry indoor applications. Typical thickness ranges from 0.5–12 mm, hole diameters 1–50 mm, with standard sheet sizes 1000×2000 mm or 1220×2440 mm.
• Galvanized Steel Perforated Sheet: suitable for outdoor and humid environments requiring corrosion resistance. Thickness typically ranges from 0.6–10 mm, hole sizes 2–40 mm, zinc coating 40–275 g/m², supplied in standard or custom panels.
• Stainless Steel Perforated Sheet (304/316): used in corrosive, hygienic, and high-temperature environments. Common thickness ranges from 0.5–8 mm, hole diameters 0.5–30 mm, with standard sheet sizes up to 1500×3000 mm.
• Aluminum Perforated Sheet: offers lightweight strength and corrosion resistance. Thickness usually ranges from 0.5–6 mm, hole sizes 1–40 mm, with large-format sheets for ceilings, facades, and acoustic panels.
• Copper Perforated Sheet: used for decorative architecture, EMI shielding, and specialized filtration. Typical thickness ranges from 0.6–5 mm, hole diameters 1–25 mm, with custom patterns and panel sizes.
• Alloy Perforated Sheet: used in demanding industrial environments requiring high strength and heat resistance. Thickness typically ranges from 1–12 mm, hole sizes 2–50 mm, with heavy-duty custom panels.

Application

• Filtration Perforated Sheet: used in liquid and air filtration systems. Small hole diameters typically range from 0.5–10 mm, with controlled pitch and high accuracy, commonly produced in stainless steel, aluminum, or carbon steel.
• Screening Perforated Sheet: used for material separation and sizing. Hole sizes usually range from 2–50 mm, with thickness 0.8–12 mm, providing strength and wear resistance for mining and industrial screening.
• Ventilation Perforated Sheet: designed for airflow and heat dissipation. Features round or slotted holes, open area 30–60%, thickness 0.5–6 mm, commonly made from galvanized steel or aluminum.
• Noise Control Perforated Sheet: applied in acoustic panels and sound barriers. Hole diameters typically range from 2–8 mm with high open area, combined with backing materials, produced in aluminum or galvanized steel.
• Safety Guarding Perforated Sheet: used for machinery and walkway protection. Medium hole sizes, thickness 1–6 mm, and high-strength carbon steel or galvanized steel provide impact resistance.
• Architectural Perforated Sheet: used for facades, ceilings, and decorative panels. Hole patterns, sheet sizes, and thicknesses from 0.8–6 mm are customizable, using aluminum, stainless steel, or copper.
