About

OUR HISTORY

Celebrating 50 Years!

Since our founding in 1975, Rainier Welding has been a trusted name in steel fabrication. Originally operating as “Rainier Iron Works,” we began by crafting high-quality fireplace inserts and freestanding stoves. In 1980, we relocated to Redmond, Washington, expanding our expertise to include general contracting, steel structure fabrication, and installation. Over the years, we’ve partnered with prominent government entities such as the University of Washington, the Cities of Seattle and Tacoma, and the U.S. Army Corps of Engineers.

In 1989, we shifted our focus exclusively to steel fabrication for the highway, industrial, and commercial sectors. With our growth came the development of advanced capabilities in value-added engineering, precision welding, and large-scale material handling. These strengths positioned us to successfully serve additional markets, including marine and bridge construction.

In 2024, under new management, Rainier Welding expanded its operations to a 4.5-acre facility in Anacortes, Washington. Over the past 50 years, we’ve proudly fabricated thousands of projects that have supported the growth and vitality of America’s infrastructure and commerce.

Rainier Welding has earned a reputation for delivering reliable, high-quality steel products that keep clients coming back. Our dedication to excellence has been recognized with numerous awards from the National Steel Bridge Alliance (a division of the American Institute of Steel Construction). Highlights include:

Today, we continue our legacy of tackling some of the most challenging and complex steel fabrication projects on the West Coast. At Rainier Welding, our mission is to build the structures that enable communities and commerce to thrive—one project at a time.

OUR VALUES

At Rainier Welding, our values are the roadmap that guides us – every decision, every action, every interaction.
They are the non-negotiables we live by.

INTEGRITY: Uncompromising honesty and ethics. Simply put, we treat others like we want to be treated.

ACCOUNTABILITY: We take responsibility. We do what we say we’ll do, when we say we we’ll do it.

SAFETY: We don’t compromise the safety of our people – for ANYTHING, EVER!

PERSEVERANCE: Success is a mindset, not a destination.  Face difficulty with grit, hard work and determination, without regard to discouragement or previous failure.

TEAMWORK: We cooperate, making personal goals secondary to customer success. Together, we can achieve what an individual alone cannot.

OUR CUSTOMERS

We are proud of the deep relationships we have cultivated with our partners over the last 45 years.  We know that we could not exist, much less thrive, without the trust and responsibility they have placed with us.  It is this pride and customer-first mind set that keeps our customers coming back year after year.

What our customers say about us.

Western Marine Construction

“Rainier Welding has been a fabricator for Western Marine Construction for many years.  They have outstanding weld capabilities and a deep understanding of the needs of projects in the marine industry.  We operate in Alaska, where delivery windows to get materials on the barge are tight, and Rainier has never let us down.  We also appreciate that Rainier will take on items outside of steel to insure that fit up happens more quickly on site, where environments can be unpredictable.”

Engineer of Bridge Support Float

“The pontoon units for the drive down float all bolted-up rather nicely and this is because Rainier is only one of two shops in the northwest with this certification and are capable of producing the level of skill and accuracy required to ensure this happens.”
