Micro Round Hole Galvanized Perforated Sheet for Electrical Cabinet Vent Dust Isolation
Micro Round Hole Galvanized Perforated Sheet for Electrical Cabinet Vent Dust Isolation
Our micro round hole galvanized perforated sheet is a dedicated ventilation and dust isolation metal panel designed for all types of electrical cabinets, distribution boxes, control cabinets and server enclosures. Thin cold rolled steel as base material with full electro-galvanized anti-rust coating, processed by high-precision CNC micro punching equipment to form dense uniform tiny round holes.
The micro-hole structure balances smooth air circulation and efficient dust interception: it realizes heat dissipation inside the cabinet to reduce component overheating failure, while blocking fine dust, floating fibers and debris from entering the cabinet to protect circuit boards, switches and electrical components. All hole edges and sheet edges are fully deburred without sharp burrs, safe for cabinet assembly and will not scratch internal wires.We stock standard thin thickness 0.6mm & 0.8mm, micro hole diameter 1.0mm~3mm, standard 1000×2000mm flat sheets in large quantity. Custom thickness, aperture, cutting size and edge wrapping processing are available. Widely supplied to electrical cabinet manufacturers, automation equipment factories and electrical hardware wholesalers all over the world with factory direct FOB price.

Product Advantages:
- Dual function of ventilation heat dissipation & dust isolation: Micro holes ensure cabinet air convection cooling, prevent fine dust from polluting electrical components and short circuit.
- Long-term anti-rust galvanized surface: Electro-galvanized zinc layer resists indoor humid air, no rust oxidation after long-term cabinet operation, avoid conductive rust debris causing equipment failure.
- Thin lightweight easy processing: 0.6/0.8mm thin gauge, convenient cutting, bending and frame welding, match all sizes of electrical cabinet vent windows.
- Burr-free safe design: Full automatic deburring removes all sharp metal edges, prevent scratch of cabinet wiring during assembly.
- Stable uniform micro aperture: CNC integrated punching ensures consistent hole size, stable ventilation and dust-block performance for mass cabinet production.
- Large ready stock fast delivery: Standard perforated sheets stored in warehouse, 3–7 working days shipment for cabinet factory bulk orders.
Production Process:
- Thin cold rolled steel coil feeding: Select uniform 0.6mm/0.8mm thin steel coil as raw material for electrical cabinet ventilation mesh.
- CNC micro round hole continuous punching: Special tiny round hole mold punches neat evenly spaced micro holes.
- Roller leveling & full deburring: Eliminate sheet warpage, polish all hole and perimeter edges to remove sharp burrs.
- Electro-galvanized anti-rust treatment: Form dense zinc protective film to block moisture and oxidation.
- Fixed-size cutting: Punching sheets cut into standard 1000×2000mm stock panels or custom cabinet vent blanks.
- Ventilation & flatness inspection: Test air permeability, hole uniformity and surface smoothness, qualified sheets classified into stock area.
