Rainier Welding

Since 1975, Rainier Welding has established itself as a trusted leader in steel and aluminum fabrication. Originally operating as Rainier Iron Works, we began by crafting fireplace inserts and stoves before expanding into steel structure fabrication in 1980. Over five decades, we have partnered with government entities like the University of Washington, the U.S. Army Corps of Engineers, and municipalities across Washington State. Our AISC-certified team specializes in precision welding, value-added engineering, and large-scale material handling for marine, bridge, infrastructure, and commercial projects. With a 35,000-square-foot facility in Anacortes, Washington, and advanced equipment including 10 overhead cranes and Voortman V600 beam drill lines, we deliver on-time, high-tolerance fabrication for challenging environments.

Recognized with awards from the National Steel Bridge Alliance, we maintain a customer-first approach, prioritizing integrity, safety, and teamwork. Our veteran-owned status reflects our commitment to excellence and service, while certifications from AISC, AWS, and SBA SDVOSB underscore our industry leadership. We serve the Northwest market, understanding the demands of harsh weather conditions and tight delivery schedules, particularly in Alaska's marine sector. Our mission remains to build structures that enable communities and commerce to thrive through relentless dedication to quality and reliability.
