San Joaquin Steel Co., Inc.

San Joaquin Steel provides competitive bids while still assuring our clients the highest quality - jobs without costly mistakes and jobs that are completed on time! Your job, from the first estimate to the final inspection, is being supervised and monitored through every critical phase of the project.

We are highly qualified individuals skilled in every phase of steel fabrication and erection. Our Sales Representatives offer service and direction, as well as our 'in-house' Estimators who are trained to establish project priorities and provide you with an overview of the entire job. Our Project Managers, Production Manager, and Purchasing Agent work closely together to assure that project material is delivered to our clients 'on site' and 'on time'. Shop Fabrication is done on the premises for quality control and product consistency. Our jobs attract quality ironworkers who value the benefits of safe, precise steel erection. Our Field Superintendent provides the latest information and direction throughout the project to meet the needs of our clients.

We are very proud that we accept nothing less than the best quality shop drawings. Our belief is that shop drawings are the key to a successful project and insist upon utmost accuracy and precision. We guarantee the best full service steel fabrication and erection. We are one of the few operations that provide bonding up to $5,000,000 single/$15,000,000 aggregate.

Our 38,000 square foot fabrication plant is situated on 13 acres of land, centrally located in Stockton.  Everything from machinery to office administration reflects the highest standard of modern technology.

A project is never too big or too challenging. Projects such as: a fuel system maintenance dock for B-52 bombers at Castle Air Force Base, flight simulator building for the F18's at Lemoore Naval Air Station, the San Joaquin County Sherriff's Complex and Jail, rebuilding the unloading towers at the Port of Stockton (a job that included underwater welding and steel erection) and the California State Women’s Prison at Madera (the largest women’s facility in the world) are just a few of our accomplishments.
