Tri-State Builder’s Supply is a regional wholesale supplier of premium building materials, serving contractors throughout a broad area of Minnesota, northern Wisconsin and Upper Michigan.

We do not deal in the mass marketed, one-size-fits-all brands typically found at big-box stores. We offer specialty building products: brands that have been engineered for exceptional beauty and performance over the long haul.

At Tri-State, we’ve built our business on the principle that a building or remodeling project is the last place to cut corners. Well-built, innovative designs and quality materials will pay for themselves in efficiency and durability. Our customers are discerning contractors who understand that building strong also builds client satisfaction and a strong business.

Products and Services

Established in 1952, Tri-State Builder’s Supply began by offering contractors some of the very first maintenance-free siding in the industry. Over the years our product line has expanded to encompass other inventive, high-performance building products including windows, doors, roofing and decking supplies.

Through it all, Tri-State’s commitment to quality and customer satisfaction has remained true: each time a contractor uses our products and services to build success, we also succeed. To this end we feature products that incorporate a wide variety of aesthetic designs, materials and colors, as well as the highest degree of workmanship and engineering. Brands like Alside, awarded the ENERGY STAR® 2013 Window of the Year, and Bayer Built exterior doors, which feature a broad selection of styles and materials also “Acclimated” for our northern climate.

In addition to detailed product information, you’ll find links here to powerful on-line tools like Alside’s Design Showcases, which allow contractors to quickly and easily customize example homes with various siding, roofing and window options—an exciting and invaluable way to help clients visualize choices and select from a multitude of styles, materials and colors.

Rest assured, however, that virtual-world resources and information are only the beginning. Tri-State’s expert staff is dedicated to helping our customers achieve real-world success and profitability: from teaching you in-home selling and marketing techniques to providing hands-on product training and jobsite support, we’re with you until the final handshake with your very satisfied homeowner.
