Acsys Inc. started development of its patented panelized building system in 1998. The product received International Code Council approval in 2000. Since then over 500 commercial and residential projects have utilized the Acsys technology throughout North America and 3 foreign countries.

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 "R-Steel" brand name.  In 2004 Bulter was acquired by BlueScope Steel and was renamed Koreteck.

During most of this time Acsys Inc. continued to supplement Koreteck production for commercial projects from it’s Idaho facility while producing the identical product under the Acsys brand name for residential applications.

In July of 2010 our licensee, Koreteck Inc., ceased operations at it’s Virginia facility due to continuing economic conditions in the construction market.  Acsys seamlessly completed several prior Koreteck Inc. projects that were under construction or in design out of the Idaho facility.

In August of 2010, to provide stronger customer focus and lower overhead costs, Acsys Inc. consolidated its commercial and residential products under one brand, Koreteck.
