Type of Lumber Characteristics 
Pressure Treated Green hue because of the chemicals used to preserve it, over time the colour fades to a silver look. Preservatives help protect the wood from attack by termites, other insects and fungal decay. Requires maintenance or sealing, paint or stain every 1-3 years.
Composite  Wood/plastic and Capped Composite wood can be used around water including docks, marinas, pools, and spas. Customizable underdeck draining, lighting and fastener-free options. Low maintenance, sustainable, resistant to rot, doesn't warp, won't giv­e people splinters, customizable, and doesn't need to be painted, stained or sealed
Brown Decking Pressure treated wood that looks like cedar. Much less corrosive to fasteners and metals than ACQ.
