San Joaquin Steel Company, a full-service steel fabricator and erector Since 1972.
Welcome to San Joaquin Steel Co. Inc. We are a full service structural steel and miscellaneous metals fabricator and erector. From a couple pipe bollards to several thousand tons we are agile enough to cover anything. Our shop is AISC Certified and we erect all of our steel with our own in-house crews of Union Ironworkers. We use only the very best outside detailing firms that we have hand picked over many years. All projects are drawn in 3D Modelling Software that allows for precise shop drawings yet easily revised to keep up with ever evolving designs and site conditions. Our shop crew is second to none and now we have complimented their output with robotic CNC equipment, same perfection but now even faster so today’s incredible delivery requirements are much easier to maintain or even improve.
