Custom lattice towers, H-frame and gantry structures, and tapered tubular steel poles for high-voltage transmission lines and take-off points — hot-dip galvanized to spec.
FabTek is a custom transmission structure manufacturer. We fabricate lattice and framed steel structures for high-voltage transmission — towers, H-frames, tapered tubular poles, and gantries built to your drawings.
For utilities 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.
Custom steel lattice towers and gantry structures for transmission lines, galvanized for decades of outdoor service.
H-frame and framed steel structures for take-off points.
Tapered tubular steel poles and crossarms.
Send drawings or a spec — we fabricate to print.







Transmission structures carry high-voltage conductors across the long spans that move power from generation to the communities that use it.
FabTek fabricates galvanized transmission and support structures engineered to withstand wind, ice, and conductor tension over open terrain. Utilities and EPC contractors rely on them for new line construction, grid hardening, and the transmission expansion driving today's record investment in the U.S. power grid.

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 transmission structures, with AWS-certified welding.
The structural steel — lattice towers, H-frames, framed structures, tapered tubular poles, and crossarms.
Lattice towers carry heavy loads and long spans at lower steel weight and ship knocked down, which suits remote or high-tension work. Tapered tubular poles erect faster, take a smaller right-of-way, and read better in populated corridors. We fabricate both, plus H-frames and gantries. Our comparison guide walks through the trade-offs.
All structures are manufactured in the United States at our facilities in Hazlehurst, Mississippi.
