STEEL IS STRONGER
Deck products have evolved over the past 20 years. Today’s composite and pvc deck boards last long, perform better and require less maintenance than their wood counterparts from past years.
However, the deck’s structure has not evolved as rapidly. Treated lumber is still used as joists, posts, and beams on most decks in the St. Louis region. The result is installing deck boards that have a 25 or 30-year warranty (or longer) on a structural system that has little or no warranty. As a natural product, wood reacts to the environment. It will split, warp, twist and shrink from exposure to the weather. Rot or decay has also been seen in some treated lumber in as little as 8-10 years, devaluing your deck.
Steel joists, beams, and posts are stronger and last longer. They will not split, crack, warp, or twist. That means your deck floor stays flat, allowing you to enjoy the deck for decades.
At Outdoor Living Inc. we use only steel structures from New Castle Steel products. The 50-year warranty on their triple-coated galvanized steel products ensures that a deck will retain its value over time. With a Class 1A fire rating you can feel safe grilling your favorite meal out on your deck. Made in the USA, New Castle Steel joists, beams, and posts are tariff-free.
Homeowners can see samples of the steel products at our showroom at 845 S. Holmes in Kirkwood. Walk on our outside decks that are supported by New Castle Steel products. Visit our website at www.outdoorlivinginc.com
