I used Trex Enhance Basics 1-in x 6-in x 12-ft for My deck. but I have about 10 Steps of size 12'' width x 4' Length - what should i use for the steps

Good morning Freddy, thank you for reaching out to us today! You can use the same Trex Enhance Clam Shell boards on the stairs but cutting your 12ft boards into 4ft sections. You will just need your stair stringers to be spaced every 9" for proper support. This is mentioned on page 24 of our decking installation guide: https://online.flippingbook.com/view/63974767/24/ You can fasten then down by face screwing with a color matching composite deck screws. We hope this helps and please give us a call at 800-289-8739 if you have any additional questions. Have a great day! -Trex Customer Care
