Gupta Metal Mesh

Round hole mild steel perforated sheets are metal sheets made from mild steel, featuring regularly spaced round holes. These sheets are commonly used for filtration, screening, ventilation, soundproofing, and decorative applications in industries such as construction, agriculture, and manufacturing.

• Material: Mild Steel

• Hole Shape: Round

• Hole Sizes: Range from as small as 1 mm up to 24 mm or more, with common sizes including 2 mm, 3 mm, 4 mm, 5 mm, 8 mm, 10 mm, 12 mm, and 20 mm.

• Pitch (Distance Between Holes): Varies by design, such as 3 mm, 5 mm, 6 mm, 8 mm, 12 mm, 15 mm, 16 mm, and 28 mm

• Sheet Thickness: Available in various thicknesses, typically from 1 mm up to 10 mm.

• Sheet Sizes: Standard sizes include 2 m x 1 m, 2.5 m x 1.25 m, 3 ft x 8 ft, and 4 ft x 8 ft.

• Open Area: The percentage of open area depends on the hole size and pitch, commonly ranging from 23% to 51%.

• Surface Finish: Options include painted, polished, or galvanized finishes for corrosion resistance.

• Construction (facades, partitions, ceiling panels)

• Industrial filtration and screening

• Ventilation panels and air diffusers

• Acoustic panels and soundproofing

• Agricultural machinery and grain processing

• Decorative elements in architecture

Round hole mild steel perforated sheets are valued for their strength, versatility, and cost-effectiveness, making them a popular choice for both functional and decorative purposes

Hexagonal perforated sheets from INDOMESH combine honeycomb aesthetics with high open area, strength, and precise fabrication, making them ideal for architectural, industrial, and design-focused applications.  

• Honeycomb aesthetics with modern, geometric visual impact for facades, ceilings, partitions, and claddings.  

• High open area for superior airflow, light transmission, and acoustic transparency compared with similar round or square patterns.

• Excellent strength‑to‑weight ratio due to the inherently efficient hexagonal geometry, suitable for light to medium structural use.

• Precise CNC/press‑tooled perforation for consistent hole size, pitch, and alignment across the full sheet area.

• Wide material range: carbon/mild steel, galvanized steel, stainless steel (304/316), aluminum, copper, and brass to suit environment and design intent.

• Multiple finishes: mill, powder-coated, anodized, brushed, polished  architectural coatings for enhanced durability and appearance.

• Architectural facades, sunscreens, balcony panels, and soffits.

• Interior wall cladding, feature ceilings, room dividers, and feature panels.

• Ventilation and air‑return grilles, equipment enclosures, machine guards.

• Acoustic backer panels in wall and ceiling systems (with insulation behind).

• Filtration, screening, and protective covers in industrial environments.

Example hexagonal specifications from industry references include patterns such as a = 8 mm, T = 10.5–15 mm with open area around 44–58%.

• Ventilation and light: High open area supports natural ventilation and daylighting while maintaining a defined external skin.

• Strength and stability: Honeycomb‑like geometry enhances rigidity and load distribution across the sheet.

• Acoustic potential: When installed with absorptive backing, the open area and pattern contribute to effective acoustic treatments in walls and ceilings.

• Design flexibility: Orientation (vertical, horizontal, or diagonal), color, and material choice allow the designer to tune transparency, shading, and visual impact.

• Custom hole size, pitch, sheet size, thickness, and pattern orientation to match project‑specific performance and design targets.

• CAD‑compatible detail support for facade, ceiling, and partition assemblies, coordinated with your fixing system and sub‑structure.

• Batch consistency, tight tolerances, and quality control aligned with demanding architectural and industrial projects.

A cold rolled round perforated sheet is a flat metal sheet manufactured using the cold rolling process, then punched or laser-cut with round holes arranged in specific patterns—most commonly staggered for strength and open area optimization.

Key Features

• Material: Often available in carbon steel, mild steel, stainless steel, and galvanized steel. Carbon steel cold rolled sheets are especially common.
• Thickness Range: Typically from 0.20 mm up to 2.50 mm for stainless steel, and up to about 1.5 mm or more for mild steel.
• Hole Sizes: Standard round holes range from as small as 0.5 mm up to 40 mm in diameter.
• Patterns: Holes are usually arranged in staggered centers (60° or 45°), maximizing open area and sheet strength.
• Open Area: Varies by hole size and pitch; for example, a 1/2" round hole on 11/16" staggered centers provides about 48% open area.

Common Specifications

Standard Sheet Sizes

• 1000 mm x 2000 mm
• 1220 mm x 2440 mm
• 4' x 8'
• 1250 mm x 2500 mm

Applications

• Architectural: Facades, partitions, ceiling panels
• Industrial: Filtration, ventilation, soundproofing, guards
• Decorative: Furniture, signage, interior design

Advantages

• Strength and Durability: Cold rolling enhances surface finish and mechanical properties.
• Precision: Consistent hole size and pattern for reliable performance.
• Versatility: Wide range of hole sizes, thicknesses, and materials for diverse uses

Summary

Cold rolled round perforated sheets are precision-engineered metal sheets with round holes, offering excellent strength, open area, and versatility for architectural, industrial, and decorative applications. They are available in various materials, thicknesses, and customisable patterns to suit specific project requirements
