4mm Aperture 2mm Hole Spacing Perforated Plate Multiple Thickness Available

Product Overview:
This dense perforated plate features standard 4mm round aperture and ultra-dense 2mm hole center spacing, produced by high-precision one-step CNC stamping to ensure consistent hole size and even distribution. We supply this punching mesh with multiple optional thicknesses, including galvanized carbon steel and food-grade SUS304 stainless steel two mainstream materials to match different working environments.

The ultra-dense hole layout brings excellent fine dust interception and balanced air permeability, widely applied as support filter mesh for air purifiers, dust-proof ventilation grille for electrical & automation cabinets, industrial liquid filter baffle, and separation screen for mechanical equipment. All panels are fully deburred and roller-leveled, flat without warpage and no sharp edges to scratch filter materials, wires or components during assembly.

Standard full-size sheets are in large stock, custom cutting, edge bending, frame welding and pre-punch mounting holes are supported. Factory direct FOB supply for filter manufacturers, electrical cabinet factories, environmental protection equipment suppliers.

Product Advantage:

• Standard fixed 4mm aperture + 2mm hole spacing: Ultra dense uniform holes, stable filtration & ventilation performance for mass production matching.
• Multiple thickness options: Cover thin lightweight 0.4mm–1.0mm for filtration support, medium 1.2–2.0mm for cabinet grille, thick heavy-duty above 2.0mm for industrial separation.
• Dual material selection: Galvanized sheet for general indoor dry environment; SUS304 stainless steel for damp, oily, weak acid anti-corrosion working condition.
• Burr-free flat surface: Automatic full deburring eliminates scratch damage to filter cotton, circuit wires during assembly.
• CNC integrated punching process: Consistent hole pitch & diameter for every batch, no deviation affecting filtration efficiency.
• Large ready stock & flexible customization: Complete thickness & material specifications stored in warehouse, fast delivery for bulk filter and cabinet orders.

Application Scenarios:

• Air Purifier & Filter Industry: Primary filter support mesh, coarse dust isolation perforated panel for air cleaner and fresh air system.
• Electrical & Automation Equipment: PLC control cabinet, server rack anti-dust ventilation grille, machine housing heat dissipation mesh.
• Environmental Protection Equipment: Industrial dust collector filter baffle, liquid waste treatment fine separation punching plate.
• Mechanical Manufacturing: Equipment internal isolation screen, anti-splash protective perforated sheet for production line.
• Hardware Processing Factory: Raw dense perforated blank material for custom filter frames and cabinet vent panels.
