Why does the DESIGNCO 4X4 system use a Hat section extrusion for the beams while others just use a Channel section?
The Hat section is a much more rigid design than the Channel section: 1.) A higher moment of inertia and section modulus are achieved with less overall height. 2.) The bottom flanges increase the ability of the beam section to resist buckling when compared with a plain channel section. 3.) The beam is extremely rigid when it is subjected to eccentric loading from the broadside direction. The fact that the beam is bolted at the top and at the two bottom flanges creates an extremely rigid member. The DESIGNCO three place bolting method is a much more desirable and practical method when compared to channels which are only bolted at the top.
