Spacer Material
Alternatives to Trex?
I need a spacer betwen a wood deck and a long, wide horizontal steel plate. It’s outdoors (a bridge). Previously, the wood deck sat directly on the steel plate, collected water, and rotted out, making the steel scale very badly.
So I want a spacer material that won’t absorb water, about 1-1/4″ thick give or take.
I’ve looked at Trex, but my understanding is it’s basically wood chips glued together with plastic. Eventually water is going to get into that, I figure?
Is there any material that I can find at a lumberyard that won’t absorb water? It needs to carry the weight of vehicles, so it needs to not compress. For instance corrugated plastic roofing won’t work…
The bridge has a steel beam that’s flat on top and about a foot wide. The old deck was treated wood and water collected and sat on this steel beam, soaked into the wood, and made both wood and steel deteriorate.
So I want something that doesn’t hold water, you know, like plastic.
pressure treated wood.
