T.W. Frierson created Design Systems Builders, LLC in 1976 to be the premier erector of Butler® Manufacturing building systems -- Our crews safely erect an average of 2 million square feet Butler® products each year, placing us among the highest producers of Butler® products in North America.

​

Recognized as the “premium product” in the pre-engineered building market, Butler® Manufacturing was chosen because of their history of quality and performance in the pre-engineered metal building segment of our industry. 

​

In 2002, we added a metal roof solution division to better serve the re-roof market. We successfully deliver re-roof solutions in a variety of applications:  “metal-over-metal”, “slope build-up”, and “complete tear off”. Each opportunity is assessed with our Clients to determine the best solution to meet their objectives. 

​

The MR-24 standing seam roof system by Butler Manufacturing is one of the  primary reasons for our association with Butler. The MR-24 system is recognized as the premier roof currently available. With its standard 25-year warranty, pre-punched secondary system and engineered performance skillfully installed by the experienced crews of DSB, the MR-24 roof system will perform leak free with simple, scheduled maintenance.
