1 Technical Data for LVL Headers, Beams, Column Applications LVL User's Guide for Residential Floor and Roof Systems CANADIAN VERSION. Quality Products Committed Service OUR HISTORY. In 1955, three Ketcham brothers, Henry Jr., William, and Samuel, acquiring two sawmills in the south. A major acquisition occurred started West Fraser by acquiring a small lumber planing mill in in 2005 with the purchase of Weldwood of Canada. With this Quesnel, BC. Throughout the years, they continued to make various purchase, West Fraser entered the engineered wood business by sawmill acquisitions in the interior of British Columbia, which acquiring the world's first continuous laminated veneer lumber press.

West 13 additional sawmills in the southern from International Paper Fraser 's expansion continued into Alberta in 1989 when they entered Co. This added billion board feet of lumber capacity to West Fraser into a joint venture newsprint mill in Whitecourt. the Company's for a total capacity of more than 6 billion board feet, making West growth continued in Alberta with the acquisition of a sawmill, MDF.
