Grande Prairie, AB

Upon its completion in late 1995, Grande Prairie was the largest oriented strand board (OSB) mill in the world. Evidence of their operational competence, the mill was designed to produce 540 million square feet of OSB per year and today it produces 700 million square feet. The same press and in-feed used in this mill were sold to a competitor shortly after, and 20 years later, that competitor is only producing 80% of the Grande Prairie mill volume.

A lot of co-ordination and planning

A break-through in innovation

The Ainsworths were the first to operate a 12-foot press in an OSB mill. This press was manufactured in Germany.
