Alliance Industrial Group (AIG)  started in 2001 as a structural steel erection company.

Along the way AIG has completed over 1,100 projects, some in excess of 10,000 tons and 1,000,000 square feet.  Winning many awards including 2013 Manufacturer of the Year award for Oregon & S.W. Washington and most recently, the 2022 AISC Best in Industry Safety Performance.

Over a decade later, AIG is still going strong.  With the addition of Alpha Iron in 2007, the ability to also provide steel fabrication has positioned the company to continue to grow in the years to come.

In August of 2014, AIG opened its new facility in Ridgefield, WA. We now have 82,000 square feet of interior manufacturing area, 30,000 square feet of exterior fabrication/manufacturing area, and 10,000 square feet of office space.  Inside our facility we have added the worlds most sophisticated equipment to ensure our customers receive the highest quality products at a competitive price.
