Built to Last
GALVASPAN® steel offers superior corrosion and fire resistance. No rot, termites, or warping—ever.
* The Steelmax Floor Framing System is made from corrosion protected BlueScope Z350 galvanised steel. This means that it will stand up to most environments, except for the most extreme situations. It is not suitable for use in applications closer than 300m to calm still coastal water or closer than 1km to rough active surf, or where exposed to corrosive elements and/or fallout from heavy industrial environments or similar.

ADJUSTABLE FOR ANY TERRAIN
Uneven Ground
Even if your yard isn't perfectly flat, your deck can be. Just cut the posts to level things out, or use our longer post with when you need more height.
Pro Tip: On slightly uneven ground, use gravel or cement tiles under the posts to even out the height.
We offer different height post kits. Each kit includes the posts and bracing. Contact our design team for more details.
Deck Height
Standard Height
Each kit comes ready to assemble at 15–17 inches off the ground.
Increase Height
Use longer posts to raise the deck. We also offer longer post kits with bracing. Chat with our design specialists for details.
Decrease Height
Dig a few inches where the footings sit to lower the deck.
