SIAG Schaaf has acquired a 70% stake in substantially all of the assets of the Tennessee-based Aerisyn, and will acquire complete interest by 2012.

Aerisyn operates a 227,000 sq ft factory and has since 2005 manufactured towers for many major turbine suppliers for wind developments in eight US states and Canada.

With the acquisition, SIAG Schaaf expands its global manufacturing capability to include seven facilities in six countries.
