1. Treated pine

Treated pine is the “new kid on the block.” It’s grown to become one of the most popular decking timbers because it is one of the least expensive options and can make a great looking deck.
Pine takes stain or paint well, so you can make your deck any colour you like. Treated pine is not all alike, though. The “H” (Hazard) rating will tell you if its suitable for outdoor use and if the posts can come in contact with the ground. A good decking supplier can help you choose the right “H” rating for your decking, joists, posts and other components.
