Custom bus duct, busduct, and busway housings — enclosed bus assemblies, copper busway enclosures, bus bar housings, and distribution assemblies for high-amperage power — fabricated, welded, and finished entirely in-house.
FabTek is a custom bus duct and busway manufacturer. We fabricate the metal housings, enclosed bus assemblies, and distribution sections that route high-amperage power — bus duct, busduct, and busway alike — built to your drawings and finished in-house, including paint.
For utilities, transformer OEMs, EPC contractors, and data center builders, single-source fabrication means tighter tolerances, consistent finishes, and schedules you can plan around. Every assembly is a domestic build, produced under an ISO 9001:2015 quality system at our facilities in Hazlehurst, Mississippi.
Metal enclosures and housings for bus duct and busduct systems, fabricated, welded, and finished in-house.
Enclosed bus assemblies and copper busway runs — straight, elbow, and transition sections built to your layout.
Bus bar housings, distribution sections, and tap-off boxes fabricated to print for power distribution.
Send drawings or a spec — we fabricate to print, including welded and bolted assembly.
Bus ducts and busways move high-current power efficiently between the major components of an electrical system.
From transformers and switchgear to distribution panels and the dense power rooms inside modern data centers, FabTek fabricates datacenter-grade bus duct and busway enclosures that carry large loads in a compact, serviceable footprint. That capability matters most where hyperscale and AI data center demand is driving record grid investment — and wherever utilities, EPC contractors, and OEMs need reliable, high-amperage distribution in tight quarters.

Each assembly moves through our own shop end to end — no outsourced steps, including paint. That's how we hold tolerances and finish quality at volume.
Fabrication runs through our laser cutting, CNC press-brake forming, robotic plasma cutting, welding, and powder-coat finishing — see our full equipment and capabilities for the machines behind each step.
Built at four production sites in Hazlehurst, Mississippi.
ISO 9001:2015 quality management, AWS-certified welding, OSHA-compliant facilities.
In-house powder-coat backed by an IEEE 2000-hour salt-spray certification.
25+ years of fabrication experience and the automation to grow with your volume.
Yes — build-to-print and custom-spec, with all work done in-house including welding, bolted assembly, and powder-coat paint.
We fabricate the metal housings, enclosures, enclosed runs, and supporting steel for bus duct and busway systems.
In practice, yes — the terms are used interchangeably for enclosed assemblies that carry high-current power between equipment. You will also see busduct, cable bus, and enclosed bus assembly. FabTek fabricates the housings for all of them.
FabTek does, as a contract fabricator building to your prints. We fabricate bus bar housings, copper busway enclosures, and tap boxes in aluminum, carbon steel, or stainless, finished in our own powder-coat line.
All assemblies are manufactured in the United States at our facilities in Hazlehurst, Mississippi.
