Hitch Standard Girts are manufactured from 16-gauge roll formed steel with a protective galvalume coating to protect it from corrosion. The shape of the Girts is that of a “hat track” and are pre-punched for ease of installation. Hitch Standard Girts are offered in depths of ¾” and 1” to accommodate different structural performance requirements. Hitch Standard Girts can be used in both horizontal and vertical applications.
