Acsys started development of the Acsys panelized building system in 1998. The product received International Code Council approval in 2000. Since then over 300 commercial and residential projects have been completed in 35 states and 3 foreign countries.

Well known brands such as Wendy's, Dominos Pizza, Saturn, and others have used the system.

Acsys granted Butler Manufacturing Company, the world's largest manufacturer of pre-engineered steel buildings, a non-exclusive license to produce the Acsys panel for the non-residential market under the "Koreteck" brand name.
