Why Green Shield uses 6x6 Deck Posts instead of 4x4

Green Shield framing serves as the foundation for a lifetime warranty. While many builders rely on standard 4x4 posts, these are prone to shrinking, warping, and premature failure due to excessive knots and moisture loss. Over time, inferior framing results in a wavy, unstable deck.

To ensure lasting craftsmanship, Green Shield exclusively uses 6x6 posts cut from the center of the tree for superior strength. Green Shield refuses to compromise on materials because these decks are engineered to last a lifetime. Our team balances this structural integrity with a refined finish, bridging the gap between elite engineering and backyard beauty.

If there are concerns regarding a deck’s structural integrity, visit greenshielddeckbuilders.com to request a no-obligation estimate. Every consultation includes a complimentary 20-point Deck Check of the existing frame to show homeowners exactly how current posts compare to Green Shield premier standards.

Hi my name is Adam with Green Shield Deck Builders. The reason that the framing is so  important at Green Shield is because we have a lifetime warranty. This product here is a  builder's grade 4x4 and this is a typical post that you would see on most decks so this would  actually have all the deck resting on it and then it would go down to a footing probably concrete.  Some of the reasons we're not going to use this because of our lifetime warranty is because it's  um it's got a lot of knots in it what's going to happen over time is this this is going to fail  prematurely and it's going to shrink because that moisture is going to start to come out of it after  it's been installed and that's going to result in a wavy deck because of our lifetime warranty we're  unable to do this type of craftsmanship so we've got to use high quality products also much larger  we've got a 6x6 next to the 4x4 here it's cut right from the center of a tree super strong  designed to last a lifetime so if you're concerned about the framing of your deck  or if you want a free no obligation estimate from green shield fill out our form on our  website greenshielddeckbuilders.com and you'll get a free complimentary 20-point  deck inspection on your existing frame and we'll take a look at your 4x4 and see how it's  holding up over time and show you the differences with the 6x6.
