The Østraadt Rør plant in Southern Norway is part of the JGO AS (Johan G. Olsen AS) group of companies, which has partly been in business since 1914. This group operates a large number of concrete plants, among them paver plants (such as ASAK AS; see BFT INTERNATIONAL 09/2006), a concrete slab production facility and plants for the manufacture of pipes and civil engineering products.
