[Greenbuilding] Alternatives to Pressure Treated Wood

[Don Eyermann]

Could the new synthetic "wood" decking be cut into strips and tapered like 
you've outlined?. Will that work for your application?...I almost feel like; 
"Certainly he's tried that...maybe his saw blade gets a build up?" I have 
not personally ripped any of those synthetic deck "boards". I've cross cut 
them to shorter lengths, with a power saw, with no problem, on a small 
scale, but that's it for me.
