I built stairs on my deck 2 years ago. I used the Veranda brand Home Depo sells. I used on the last home & it looked great 10 yrs later when we moved. We get snow and heat (95 today) so it gets a workout. Plus- it doesn’t split. Minus- it will burn your feet. I have a 10x38 ft deck I want to use the material on & replace the old split & knot holed redwood that looks like shit. For now, I pained the deck boards to match the composite. Good fall project before it gets below freezing.
