Build-to-print tanks, cabinets, and coil assemblies for transformer manufacturers.
FabTek is a contract fabrication and assembly partner for transformer manufacturers — building transformer tanks, cabinets and enclosures, and coils, windings, and core-and-coil assemblies to your design, on dedicated lines sized to your demand.
Transformer OEMs are caught between surging demand and constrained capacity. The partners worth keeping are the ones who can reserve a line, hold tight tolerances run after run, and supply both the metal and the electrical build — without you having to coordinate two separate supply chains.
FabTek is a rare single source for that combination: metal fabrication and coil/circuit assembly under one ISO 9001:2015 roof, with the confidentiality, documentation, and consistency that build-to-print OEM work demands.
Transformer OEMs are caught between record order books and a supply base that can’t keep up. The contract partners worth keeping are the ones who can reserve a line, hold tight tolerances run after run, and supply both the metal and the electrical — without you coordinating two separate supply chains. FabTek is a rare single source for that combination — tanks, cabinets, and coil assemblies under one ISO 9001:2015 roof, on dedicated lines sized to your demand.
When your fabricator treats your recurring program like spot work, you’re re-negotiating capacity every release — and your production plan is only as firm as their backlog allows.
Sourcing the tank and cabinet from one vendor and the coils from another means more suppliers to qualify, more handoffs, and more places for tolerances and schedules to drift apart.
Different teams, machines, or processes batch to batch introduce variation your assembly line and your customers can’t absorb on a build-to-print component.
Contract work demands confidentiality and airtight records. A partner who can’t protect your prints — or can’t produce the traceability — is a risk to your program and your reputation.
OEM programs live and die on consistency and capacity. FabTek stands up dedicated production lines and reserved monthly capacity for recurring transformer components — the same team, the same machines, the same process — so the hundredth unit matches the first and your demand forecast is something we plan around together.
Because we build both the cabinet and the coiling, you get a single accountable source for the metal and the electrical. That means fewer suppliers to qualify, fewer handoffs where tolerances drift, and one quality system covering the whole component.
Your designs stay yours. FabTek works strictly build-to-print under confidentiality, with material traceability, weld documentation, and inspection records on every run.

Send prints and specifications — under confidentiality — for the tanks, cabinets, or coil assemblies you need.
We return pricing, lead times, and a dedicated-capacity plan matched to your production forecast.
Your parts run on a dedicated line under ISO 9001:2015, with consistent tolerances every batch.
Components ship with material traceability, weld records, and inspection documentation.
FabTek fabricates transformer tanks and welded vessels, transformer cabinets and NEMA-rated enclosures, and coils, windings, and core-and-coil assemblies — all built to your design under one quality system.
Yes. FabTek stands up dedicated production lines and reserves monthly capacity for recurring OEM programs, so the same team and machines run your parts consistently and your demand is planned around.
Yes. FabTek is a rare single source for both the metal and the electrical — we build the cabinet and the coiling — which reduces the number of suppliers you have to qualify and manage.
FabTek works strictly build-to-print under confidentiality. We fabricate to your prints and do not repurpose your designs, and we maintain documentation and traceability throughout.
Yes. With automation, dual-shift capability, and reserved capacity, FabTek is built to ramp dedicated lines as your transformer volume grows.
FabTek operates an ISO 9001:2015 quality management system with AWS-certified welding and OSHA-compliant facilities, and provides full material traceability and inspection records.
