Data Center Infrastructure
Built for Density & Cooling

HFI Manufacturing fabricates racks, cabinets, and thermal management components for data center operators and infrastructure OEMs. Precision sheet metal built for high-density deployments.

Infrastructure for the Modern Data Center

Data center infrastructure demands precision-fabricated racks, cabinets, and air management components that maximize density while maintaining efficient cooling. HFI builds components that meet 19″ EIA standards and support hot-aisle / cold-aisle containment strategies.

We work with your team to integrate cable management, busway provisions, and airflow direction features directly into the fabrication — reducing installation time and improving PUE.

Our Data Center Capabilities

Fabrication processes designed for the precision, density, and thermal requirements of modern data centers.

Quality

ISO 9001-certified quality system with full traceability, in-process inspections, and documented verification—ensuring every component meets mission-critical performance requirements.

Cutting

Fiber laser cuts stainless up to 1/2″ with burr-free edges. No secondary deburring required for most food-contact surfaces.

Bending

CNC press brakes handle up to 7ga steel for structural rack frames. Consistent ±0.005″ across every bend.

Welding

Robotic MIG welding for high-volume rack frames. TIG finishing for visible seams on front doors and trim.

Assembly & Kitting

Cage nuts, cable managers, fan trays, PDUs, and busway mounts installed prior to shipment. Doors hung and aligned.

Finishing

Textured and smooth powder coat finishes in black, white, or custom RAL colors. ESD-safe coatings available for sensitive environments.
