The low-side steel that carries every piece of equipment in the yard — bus supports, disconnect switch stands, breaker and CT/PT stands, arrester and metering supports — fabricated, galvanized and match-marked to your structures package.
A structures package for a single substation can carry forty or more equipment stands and bus supports, and every one of them has to land on an anchor-bolt pattern poured weeks earlier and present a mounting face that matches an equipment submittal from a different vendor. The steel is not complicated. The coordination is.
FabTek fabricates the complete low-side steel scope — rigid and strain bus supports, switch stands for vertical-break and V-switches, breaker stands, CT and PT stands, arrester stands, metering supports and wave-trap supports — to the utility's or EPC's drawings at our Hazlehurst, Mississippi plants. Robotic plasma processing on the Voortman V807 gives us repeatable hole patterns across a package; certified welders work to AWS D1.1; every piece is hot-dip galvanized to ASTM A123 and match-marked so the erector can find it. Anchor-bolt patterns are checked against the foundation drawings before the first cut.
Rigid-bus and strain-bus supports, single- and multi-phase, for A-frame, tubular and lattice-style yards.
Stands for group-operated disconnect switches, vertical-break and V-switches, with operator platforms and interphase linkage supports where specified.
Breaker stands, CT/PT/CCVT stands, surge-arrester stands, station-service transformer stands, wave-trap and line-tuner supports.
Metering structures, junction-box stands, cable-trench covers and grating supports, grounding and fence hardware brackets.
Low-side steel appears in every substation and switchyard — transmission, distribution, generation switchyards and the customer-owned substations serving data center campuses and industrial plants. It is also the part of the package most exposed to late design changes, because equipment submittals arrive after the steel is detailed.
Utilities specify stands to their own standard drawings and expect a fabricator to hold them exactly; EPCs buy them as part of a turnkey scope and need delivery sequenced to the erection plan; data center developers buying a substation directly need a fabricator who can walk them through what a structures package contains. Our substation steel for data centers guide covers that last case.

Equipment stands are where change orders land. A breaker is substituted, a switch operator moves to the other side, a foundation gets shifted around a duct bank. We hold the package in a revision-controlled release so a change to one stand doesn't hold up the forty that didn't change, and we say clearly which pieces are affected and what the schedule impact is before anyone approves it. Our guide to managing late design changes explains the process.
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.
Reserved-line capacity and the automation to grow with your volume.
Yes — bus supports, switch stands, breaker, CT/PT and arrester stands, and metering supports, fabricated to the utility's or EPC's drawings, galvanized and match-marked.
FabTek fabricates complete low-side steel packages at its Hazlehurst, Mississippi plants and ships nationwide, with field erection available from its own crews.
We check every stand's base plate against the foundation drawings before cutting, and against the as-built survey when the customer provides one. Our anchor-bolt spec sheet covers the tolerances involved.
Yes. Most customers buy the full structures package — dead-ends, A-frames, bus supports and equipment stands — from FabTek as one release with one set of documentation.
