Bilingual crew for mixed job sites

Montebello and the surrounding San Gabriel Valley manufacturing belt keep a fabricator busy with production equipment steel, stainless process lines, and the structural repairs that come with older industrial buildings.

Our bilingual crew works easily alongside the plant teams in this part of the county, which matters when a tie-in has to be coordinated with operators on a live line.

Spools and steel are fabricated in Colton and delivered down the 60; field welding is scheduled around production.
