A third-generation family company.
What began as Martin's Welding on Vine Street in Vacaville has grown into one of Northern California's most trusted steel fabricators.
Built from one couple's dream.
In 1972 Len and Carol Martin opened a small, family owned and operated welding shop on their property on Vine Street in Vacaville.
Len had found his niche working sheet metal in the U.S. Air Force. Carol ran the business side with the same work ethic — still in the office at 75, giving 100%. With the help of their four children, they grew Martin's Welding into Martin's Metal Fabrication & Welding, Inc.
Under David Martin's leadership the company grew from a small crew in the 1980s to more than 100 employees by 2014. Today the third generation helps run the business, and the values Len and Carol set are still how we work every day.
