The family business Helland Silo System at Ålgård in Gjesdal municipality in Rogaland produces perhaps the country's best-known silo.
The founder Ingolv Helland began producing fully welded steel silos in a sixty square meter basement room in his home on Ålgård in 1965, as a response to feed producers’ change from deliveries in 50 kilo bags to bulk deliveries from cars. Since then, the Norwegian silo producer has delivered several thousand concentrate silos to farmers all over Norway.
At the beginning of the 70s, Helland switched to producing bolted silos on self-developed production machines, which resulted in the silo model 300S.
