Telecom Enclosures
Built for Protection & Reliability
HFI Manufacturing fabricates telecom enclosures, cabinets, and racks for indoor and outdoor infrastructure. NEMA-rated designs built to protect sensitive equipment in any environment.
Enclosures Built for the Network Edge
Telecom infrastructure demands enclosures that protect sensitive electronics from weather, dust, vibration, and temperature extremes. HFI builds cabinets and racks that meet NEMA, IP, and customer-specific environmental ratings — from central office to remote deployment.
Our team works with your engineers to integrate cable management, thermal management, and mounting provisions directly into the fabrication design, reducing assembly time and field installation costs.

Our Telecom Enclosure Capabilities
Fabrication processes designed for weather-sealed, thermally managed, and vandal-resistant enclosures.
ISO 9001-certified quality with documented inspections, CMM verification, and fit-up validation to ensure weather-sealed enclosures, consistent tolerances, and reliable performance in demanding telecom environments.
Fiber laser cuts steel and aluminum with burr-free edges. Clean cutouts for knockouts, vents, and cable entry plates.
CNC press brakes handle 10ga steel and 3/16″ aluminum. Consistent bend angles for gasket-compression sealing surfaces.
Continuous seam welding for weather-tight enclosures. Robotic MIG for high-volume cabinet bodies, TIG for cosmetic visible surfaces.
Hinges, latches, ground studs, cable glands, and PEM hardware installed. Doors hung and aligned prior to shipment.
Powder coating in RAL or custom colors. Outdoor-grade UV-resistant finishes with salt spray testing available.
