Aluminum track vs low profile track

I am replacing the bifold door track on a customers 8 foot opening that had two four foot tracks mounted overhead. The existing track is pretty bent up so I want to replace it with new. The 24 inch bifold doors are fairly heavy and I want to make sure the track I install is strong enough to hold up. Your item number 21-404 looks like it would work for me but I wondered if the aluminum track is as strong or stronger than the low profile track you sell.

Thank you,

Bob
