Backed by Holloway Holdings , our operation is supported by a full parts department, experienced service managers, and the capabilities of trusted industrial brands, including On-Site Services (TX) — a leader in Gas, Oil, Railroad, and Utility (GORU) work.

Real-World Experience

From marine winches to trailer overhauls and critical lifting equipment, our team brings proven experience from jobs that demand excellence. We’ve supported operations for Boise Cascade, handled structural projects for local municipalities, and contributed to infrastructure for the Union Pacific Railroad. We also give back — with donated fabrication work for the local gun club and rodeo circuits. Our team includes welders previously certified to x-ray pipe standards — even though piping isn’t our current focus, that level of precision informs everything we do.
