When it rains, it pours, which it usually does in the Pacific Northwest. You need to keep things waterproof as well as rustproof. The engineers at Great Western Steel Building Systems have the solution.

From Puget Sound to the rocky shores of Oregon; the imposing mountains of eastern Washington to the farms of Northern Idaho, America’s Northwest has some of the most beautiful landscapes on earth. And some of the dampest.

Water is both the draw and the drawback to the region – believe it or not, the easiest, most affordable, and most durable solution is a rust-proof, easy-to-erect, galvanized, steel building.

Rust is an issue in an area with so much moisture. Avoiding roof leaks that can damage interior valuables is another. Industry and commerce, even Northwest manufacturing is known to require oversized, clear-span structures, able to withstand the elements. What’s the one-stop solution? Washington Steel Building Kit shortens erection time and helps you avoid issues on site.

The engineers at Great Western have an intimate understanding of wind loads, foundation requirements, moisture issues, and even the delivery and storage challenges South Eastern residents might face during the erection process.

  • Easy-to-read and detailed erection guides
  • We work with you to find the right roof pitch, wind load, and even color
  • We adhere to the most current IBC standards for the Northwest
  • Large-scale commercial buildings, farming and ranching, and even a backyard workshop – we’ve got you covered – literally.
