I assembled each tread during the winter months and found that every tread cracked. This cracking was on the ends and sides of every 4X6 tread frame. I worried and fretted all winter about this. In the spring I screwed everything together and installed the stair. That was about 25 years ago. no further cracking and detectable structural problems. So don't worry about it! |
