'Aluminum standards and data show the same typical yield and ultimate
strength for T52 and T5, so you'd use the the same allowables. The
allowables you've quoted are applicable to building structures--you might
want to give some thought to using the lower allowables for bridge type
structures since you need some impact resistance on the rails.
