ABOUT STEELSEN
Idaho-Based. Built to
Work Anywhere.
e started Steelsen because builders and homeowners deserved a supplier who understood both the climate and the craft — without the run-around of going out of state for quality aluminum and wood products. We're based in Boise, and we work with projects well beyond it
"Every opening in a home is a chance to connect the inside with the outside. We take that seriously."
STEELSEN FOUNDER
Whether it's a custom home in the Foothills or a commercial development across the region, we work directly with homeowners, builders, and developers to specify the right product — and back it up from order through install.
