You can make this standard replacement track last virtually forever by flipping it over when you first get it, and filling the hollow cavities with either JB weld compound (best bet) pr a strong fiberglass resin. Take the ends so it doesn't run out and let it harden for 48 hrs indoors. You want the filler to be flush with the edges of the rail when done. The flip it over, take off end tape and screw it down. Now when you stop on it, it will be very solid and will not bend. Of course, everything has limits but a normal person walking on it over. 15 years will not bother it. I have the same exact rail and this is what I did. It costs a little extra money but is easy and makes it very sturdy.
I am looking for a track similar to the one shown in the picture. It is 82 inches long
