If you’re looking for a authentic wood look, pressure-treated wood is your best option. Pressure-treated wood is the most popular choice among wood deck materials, but other more expensive materials include cedar, redwood, and tropical hardwoods.
Most pressure-treated wood is made from Southern yellow pine, which splinters if not maintained. Wood does require much more maintenance then composite or vinyl decking. Deck stain should be applied every 1-3 years.
Pressure treated wood is infused with chemicals that are corrosive so for best results, use only stainless steel or acq approved fasteners.
