- Ironwood's density is nearly six times that of pressure treated pine, and that strength provides some very practical advantages. Unlike redwood, Ironwood decking planks will not crack or split over time. Unlike cedar or pine, Ironwood won't splinter. Unlike some vinyl composites, Ironwood won't become slippery when wet because its surface won't become smooth from foot traffic. Ironwood is so hard, in fact, that installers are urged to used carbide tipped saw blades and carbide drill bits in constructing your deck.
- A new Ironwood deck displays a deep brown color with a tight grain structure that is free of the knotty contrast common to softer woods. You can maintain that color by applying a semi-transparent stain every year or two, which will help extend the life of the deck for 50 to 100 years. You won't need to apply a sealant because water can barely penetrate Ironwood's dense pore structure. If you choose to forgo staining, Ironwood will take on an attractive gray cast, but it may last only 40 to 50 years. That's still a much longer expected lifespan than most wood or vinyl decking materials.
- Ironwood is naturally resistant to termites and boring insects such as carpenter bees, and it resists mold as well. Like concrete and steel, Ironwood carries a Class A Fire Resistant rating. Unlike most wood decking products, Ironwood is safe for ground contact. Unlike plastic composites, Ironwood is not vulnerable to permanent stains from red wine, barbecue sauce, or black mold. Ironwood will not suffer damage from summer heat or winter cold cycles that cause some woods to warp or curl. Unlike vinyl decking, Ironwood does not become uncomfortably hot underfoot on hot summer days.
- Pressure treated wood must be infused with chemicals to retard the rapid decay process common to softer woods. Plastic composite decking may feature an embossed or extruded surface that forms a rough but unconvincing approximation of wood texture or coloration. Ironwood, on the other hand, maintains the natural beauty of real wood without utilizing harsh chemical additives or plasticizers, and you can even obtain it from forests that are environmentally certified by the Forest Stewardship Council.
