Substation & Switchyard Structures and Support Steel
Custom substation and switchyard steel — A-frame, dead-end, gantry, bus-support, and goalpost structures — plus the support steel that holds a substation together.
Custom substation and switchyard steel — A-frame, dead-end, gantry, bus-support, and goalpost structures — plus the support steel that holds a substation together.
FabTek is a custom substation steel fabricator and supplier. We build the structural steel and support steelwork that holds a substation or switchyard together — A-frame, bus-support, and dead-end structures, equipment supports, and support steel, built to your drawings.
For utilities, public power, and EPC contractors, single-source fabrication means tighter tolerances and schedules you can plan around. Every structure is a domestic build under an ISO 9001:2015 quality system in Hazlehurst, Mississippi.
Strain, dead-end, A-frame, and H-frame substation structures fabricated to your drawings.
Gantry, goalpost, and bus-support structures for substation and switchyard buswork.
Stands, brackets, substation steel frames, and structural steel for substation equipment.
Send drawings or a spec — we fabricate to print.
Substation support structures and steel form the backbone of every substation, holding transmission and distribution equipment in precise position under heavy mechanical and environmental load.
FabTek fabricates dead-end and A-frame structures, equipment supports, and heavy galvanized beam for utility-scale substation builds. EPC contractors and utilities depend on these structures to carry buswork, switches, transformers, and conductors safely for the multi-decade life of a substation.

Each build 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. We fabricate build-to-print and custom-spec substation structures and support steel, with AWS-certified welding.
The structural steel — A-frame, bus-support, and dead-end structures, equipment supports, and support steel — not the energized apparatus.
Yes. Switchyard steel, gantry and goalpost structures, H-frame and A-frame strain structures, dead-ends, and bus supports are all standard work for us, fabricated to your drawings or PE-stamped design.
Both. Substation and switchyard steel is normally hot-dip galvanized to ASTM A123, and we also run in-house powder coat when the spec calls for it — including storm-hardening and coastal corrosion requirements.
All structures are manufactured in the United States at our facilities in Hazlehurst, Mississippi.
