Slotted Perforated Metal Sheets

Slotted Perforated Metal Sheet Overview

A slotted perforated metal sheet (also called slot-hole or oblong-hole perforated sheet metal) is a type of perforated metal sheets made by CNC punching or laser cutting from steel, stainless steel, aluminum, or galvanized sheet, then finished to match your project requirements. Compared with round hole perforated metal sheets, slot patterns can deliver strong airflow and drainage with fewer blockages, which is why they’re common in screening and ventilation. If your priority is acoustic control, micro perforated metal sheets are usually the better fit.

• Length: 0.1m – 4m (custom sizes available)

• Width: 0.1m – 1.5m (custom sizes available)

• Thickness: 0.3mm – 20mm

• Materials: Carbon steel, stainless steel, aluminum, galvanized steel, copper

• Hole patterns: Straight slot, round-end slot, staggered slot, decorative slot design, Layout options include straight-row (in-line) patterns and staggered arrangements (such as Z-type or K-type layouts), depending on the open area you need and the strength you want to keep.

• Hole size: From 1×2mm to 50×100mm, or customized per drawing, In addition to slot size (W×L), we can manufacture to your pitch (center-to-center spacing) and target open area percentage. Just tell us the required edge margin/border so the sheet stays rigid during installation.

Slotted hole design allows a higher open area and smoother material flow, making slotted perforated metal sheets ideal for screening, filtration, and ventilation applications. Typical use cases include vibrating screen decks, grain and flour sieves, filter guards, HVAC return/air intake panels, machine enclosures, and drain/overflow protection where steady flow matters.

Solving Customer Pain Points with Slotted Perforated Sheets

When sourcing perforated metal products, customers often face issues such as: Most problems come from missing specification details—slot size, pitch, layout, edge margin, material, thickness, and finish—so we help you confirm every parameter before production.

• Difficulty finding the right slotted perforated metal sheet size or hole pattern

• Lack of factories that support small-batch customization

• Poor surface finishing, leading to rust and short lifespan

• Long lead times delaying projects

We solve these issues with made-to-order slot perforated sheets, fast sampling, and controlled production—plus finishing options that match indoor, outdoor, and corrosive environments.

Custom Manufacturing Capabilities for Slotted Perforated Metal Sheets

Our factory provides full-range processing for slotted perforated metal sheets:

• Deburring – Removing sharp edges and burrs for safer handling and cleaner assembly

• Bending – U-shaped, L-shaped, or curved panels

• Welding – Assembling with structural components

• Rolling – Cylinder-shaped filters and housings

• Laser cutting – Precise edges and smooth finish

• Surface treatments – Powder coating for color and outdoor durability, galvanizing for carbon steel, polishing for clean finishes, and anodizing for aluminum. For corrosive environments, consider stainless steel perforated metal sheets or aluminium perforated metal sheets.

Custom Slotted Perforated Metal Sheet Production Process

1. Requirement consultation (size, hole type, drawings)

2. Technical solution & quotation

3. Sample sheet for approval (confirm slot size, pitch, open area, flatness, and edge condition)

4. Mass production with strict quality control

5. Surface finishing for durability and aesthetics

6. After perforation, sheets can distort—especially with dense patterns—so we use leveling/flattening processes to improve flatness before shipment. Each order is checked for dimensions and hole consistency, then packed to protect edges and surfaces in transit.

Applications of Slotted Perforated Metal Sheet

Thanks to its drainage and ventilation benefits, the slotted perforated metal sheet is widely applied in, In many projects, these are specified as perforated panels because the slot pattern balances airflow with strength:

• Architecture – Facades, ceilings, partitions, railings

• Machinery – Vent panels, safety covers, soundproofing

• Food processing – Drying trays, filters, flour sieves

• Mining and quarrying – Coal classification, stone screening

• Environmental protection – Dust collection, wastewater treatment, oil-water separation
