Post Deck Stairs



I am planning on replacing my wood decking with Trex and have a question regarding the stairs. Attached is a picture of the stairs. The tread is 36" wide, with the posts and balusters mounted on the outside of the skirt board. Mounted flush on the inside of each skirt board are the stringers, which can't be seen from the picture. The concrete slab is 46" wide. My plan is to install the new posts on the inside of the stringers, with the treads notched around the posts. In essence, the treads will still measure 36" wide, but the new position of the posts on the interior of the stringers will seem to shorten the overall space between both railings. Is this still appropriate? What other options may I consider that could be more appropriate? Thanks for your time.

Welcome to the forums! http://www.doityourself.com/forum/el...your-post.html

If you mount the posts inside the stringers, you will need to band the posts at the level of the stringer tread so you will have something for the tread to attach to. In addition we need to know how many stringers you have, as Trex requires a more rigid support system.

Installing the posts inside will leave 29 inches between the posts.

Off the top of my head, Trex wants no more than 12" or so between support on stair treads, so this isn't even close.

Width

My comment in post #3 is directed toward the width requirement for stairs.
