About Us

In 1950, Rex Robertson had a vision and saw a need in the community. He started Pella Windows & Rex Robertson Co., working out of an old railroad car at the same location that we operate on now over 60 years later. When his son Jim took over in 1974, we began selling hollow metal building supplies! With the addition of Denis Hoerle and Paul Parke, we became the go-to guys for commercial doors and hardware. To this day, we still strive to maintain the integrity that has made us great for over 60 years! Going the extra mile ensures you have an excellent experience and that your project is done right the first time! With thousands of products from over 30 vendors, rest assured that you’ll have access to the items you need. The railroad car may be gone, but we are here and eager to serve you in the Casper and Gillette, WY, area!
