Spanish- and English-speaking crew

Santa Ana and central Orange County combine older industrial neighborhoods with newer manufacturing and medical-device facilities in Irvine and Tustin. We fabricate stainless tubing and process piping, structural supports, and custom weldments for both.

Our bilingual crew is an asset on Santa Ana job sites where coordination happens in Spanish as often as English.

Shop work ships from Colton; field welding and installation are scheduled around your facility's hours.
