Security Doors
Rigid perforated panels for entry doors and protective screen assemblies.
Round-Hole Alloy Security Mesh
Round-hole alloy security mesh is made from a galvanized-alloy panel with uniformly punched openings and a protective coating. Its rigid construction provides dependable door and window protection while preserving controlled airflow and a neat architectural appearance.
It is suitable for security doors, windows, balcony openings, ventilation panels, and custom enclosure systems. Aperture, pitch, panel thickness, dimensions, finish color, and frame-matching details can be selected for each project.
Product Advantages
- Rigid perforated panel: Continuous alloy sections retain their form and spread localized force.
- Uniform ventilation: Regular round apertures provide consistent airflow across the panel.
- Protected surface: Electrophoretic priming and powder coating help isolate the galvanized substrate.
- Architectural appearance: Precise hole spacing creates a clean, orderly look in finished frames.
- Project customization: Aperture, pitch, thickness, size, color, and fixing details can be adapted.
Structure
The mesh starts as a galvanized-alloy sheet that is precision punched into evenly spaced round openings. An electrophoretic base layer and composite powder coating protect the panel, while cut edges and fixing points can be prepared to suit the specified frame.
Working Principle
The continuous metal between adjacent openings gives the panel its stiffness and helps distribute localized force across a wider area. The round apertures maintain ventilation and outward visibility without sacrificing the stable, tamper-resistant form of a perforated panel.
