Pressure Treated Lumber

Spray Lake Sawmills is known for the consistent quality of all it’s treated products. Discerning retail dealers and contractors throughout western Canada will only buy treated wood with the distinctive SLS Diamond on the wrap. 

You won’t find the SLS Diamond in a box store. We produce a full range of consumer products for outdoor home construction in our Sienna Brown (MCA).

Our Cochrane team is proud to be the leader on new technology and treatments as well as environmental standards. Spray Lake Sawmills was the first treatment facility in Canada to meet Wood Preservation Canada’s TRD requirements for environmental excellence. We operate two treatment facilities on our site using different preservatives.

Lumber products produced at our Cochrane site are available throughout western Canada at select retail dealers.
