Our round hole perforated metal sheets are widely used for decoration, filtration, acoustics, ventilation, and machinery guards. All key parameters can be customized to match your drawing, sample, or performance requirements.
Typical specifications (customizable):
If you’re specifying a round-hole sheet for the first time, focus on four items: material, thickness, hole diameter, and pitch (center-to-center distance). Once those are set, we can confirm the best layout, margins, and manufacturing method for your application.
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, and carbon steel (cold-rolled or hot-rolled). Copper and other alloys are also available upon request.
Hole type: Round holes (single row, staggered, or multi-diameter layouts), Common layouts include 60° staggered (a strong choice for higher open area), 90° straight rows (easy alignment), and custom mixed patterns for visual design. If you need a quick estimate, use the Open Area & Weight Calculator tab, or check the Inventory list tab for fast-ship options.
Hole diameter: φ0.8 mm — φ50 mm (and larger on request). For ultra-fine holes used in precision ventilation and acoustic liners, please see our Micro Perforated Metal Sheets.
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, For design reviews, we can confirm the percent open area based on your exact layout and provide a sample panel or inspection report when needed.
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:
Round holes are often selected when you want predictable airflow, consistent screening performance, and an easy-to-maintain surface. They also work well for architectural perforated panels where a clean, balanced appearance matters.
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: Round holes tend to trap less debris than long slots, which can help in washdown or hygiene-focused areas. If your application needs elongated openings for material flow, consider Slotted Perforated Metal Sheets.
Round Hole Perforated Metal Sheets Pattern Display
For most buyers, the real risk is not the hole pattern—it’s whether the delivered sheets match the drawing and stay flat after perforation. We control burrs, flatness, and surface protection so your parts are ready for installation or downstream fabrication.
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: hole size and pitch are controlled to a tight tolerance based on your material and thickness (typical capability: ±0.1–0.2 mm; tighter tolerances can be reviewed case by case).
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.
