About Us

Stirnco Steel is proud to be a General Contractor. We create jobs, and we greatly appreciate that hardly a single endeavor in the country does not involve the construction industry. We are honored to have been provided the opportunity to build many of the manufacturing facilities, retail stores, specialty buildings, and sports facilities that support the communities we live and work in.

Stirnco has been designing and building industrial construction projects for a select and discriminating group of business customers since 1980. Completed projects, from southern Oregon to Fairbanks, Alaska, have included new buildings ranging in size from 4,000 sq. ft. to 80,000 sq. ft. Designs include pre-engineered steel buildings (Stirnco is a Nucor Building Systems Dealer), structural steel, CMU, tilt-ups, insulated tilt-ups, glass, steel stud and wood framing systems.

Stirnco's strength is our ability to translate a business's needs into the most cost-effective design solution. Quality of initial construction is emphasized to avoid long term maintenance costs and headaches. Stirnco is a "high caring," not a "high volume" company. If this approach is attractive to you, we invite you to explore our site and call us with any follow up inquiries.

Stirnco was established in 1980 by its current Owner, Dale Stirn. After graduating from Harvey Mudd College of Science and Engineering with a B.S. degree in mathematics and extensive course work in engineering and physics, Dale spent three years teaching Mathematics as a Peace Corps volunteer in Botswana, Africa, and then a year in Washington’s Governor’s office under Dan Evans assisting in the preparation of Evan’s last two year state budget before leaving office.  After two years as Systems and Procedures Coordinator in the Wa. State Dept. of Revenue, Dale decided he wanted to venture out into the private sector.

Growing up, Dale had always worked with his Dad on small construction projects and enjoyed the combination of physical work and the challenges that construction work presented.  In 1977 Dale went into business with a partner designing and constructing steel building projects, and in 1980 he formed his own company.

Stirnco knows and understands the pluses and minuses of virtually all steel building products.  We have erected steel buildings manufactured by Butler Manufacturing, Varco Pruden, Star, PBS, Sun, HCI, R&M, Metallic, and Nucor. 

From the beginning,  Stirnco has been a company driven by customer desire to work closely with their builder.  While Stirnco has grown in size and capabilities, customers have always had direct contact with Dale Stirn throughout  the planning, costing, permitting and constructing of their projects.  This relationship has led to a level of customer satisfaction not typically found in the construction industry.

Stirnco brings unique skills to a project with a level of design and pre-project costing expertise not typical to a construction company.  Most of Stirnco’s projects are designed in-house to a prescribed customer budget, drawing on the experience of many years constructing industrial and commercial projects to make sure the project meets customer design and cost expectations.

Stirnco has designed and constructed projects in Washington, Oregon, Alaska and Hawaii.  Projects have ranged in cost from $25,000 to $5,000,000.  All involve some form of metal building but may also include concrete tilt-up or masonry walls, glass, and wood-framed office structures where appropriate.

Stirnco has a bonding capacity of $5,000,000 on any single project.
