China wholesale Insulated Double Garage Door - garage door struts 16 foot – Bestar Detail:

Garage door struts stiffen door sections to prevent them from bending or breaking. They also allow the door to open and close smoothly. If the sections are not rigid, the garage door will bind as it opens and closes.

Most residential doors use 2” struts, but residential and industrial doors over 16 feet wide often use 3” struts. Struts are normally two inches shorter than the door width.

L-shaped metal reinforcement members attached horizontally to the inside of the garage door section to add strength and rigidity. It also called trusses.
