SenChi - Round Hole Perforated Metal Sheets

• Plate length: up to 6000 mm (longer available by splicing), Products with a sheet thickness less than 0.8mm can be supplied in coiled form; the standard length is 20 meters per coil, but other lengths can be customized according to requirements.

• Plate width: up to 1500 mm

• Plate thickness: 0.2 mm — 30 mm (common: 1.0 / 1.2 / 2.0 / 3.0 /4.0 /5.0 mm)

• Materials: Stainless steel (201/304/316), galvanized steel, Galvalume, aluminum alloys, cold-rolled or hot-rolled steel, copper, etc.

• Hole type: Round holes (single row, staggered, or multi-diameter layouts)

• Hole diameter: φ0.8 mm — φ50 mm (precision punching available for smaller sizes)

• Pitch: customizable — Products can be customized as long as the edge-to-edge distance between holes exceeds the sheet thickness.

• Open area: 5% — 60% depending on hole size and pitch

• Surface finish: Polished, brushed, sandblasted, powder coated, wet paint, hot-dip galvanized, electroplated, anodized, etc.

Why round-hole perforated metal sheets stand out from other patterns:

• Strength and durability: Circular holes reduce stress concentration, improving fatigue resistance.

• Efficient manufacturing: Punching and CNC processing of round holes is cost-effective and highly repeatable.

• Predictable airflow and acoustics: Open area calculations are straightforward, making design optimization easier.

• Aesthetic versatility: Round holes deliver a clean, balanced look that fits both industrial and architectural design.

• Easy cleaning: Less dust accumulation compared to slotted or irregular holes, making sheets ideal for hygienic industries.

Pain points:

• Difficulty sourcing exact hole size, pitch, or material.

• Standard perforated metal sheets don’t meet special open area or thickness requirements.

• Lack of factories providing perforation plus bending, welding, and finishing in one place.

• Long lead times or no quality documentation.

• Concerns over deformation, burrs, or scratches.

Solutions:

• Fully customized round-hole perforated metal sheets: tight tolerance hole control (±0.1 mm available).

• One-stop service: cutting, perforation, bending, rolling, welding, finishing — all under one roof.

• Sample verification: samples or pilot runs available before mass production, with inspection reports.

• Quality assurance: deburring, anti-deformation fixtures, and flatness control.

• Technical support: engineering team reviews drawings and recommends cost-effective solutions.

We specialize in fabricating round-hole perforated metal sheets with advanced equipment and secondary processing:
