Metal trusses can be designed and fabricated to meet almost any application. Light gauge trusses can achieve straight spans of up to 40' and weight anywhere from 33% to 200% lighter than there steel or wood counterparts.
There is virtually zero waste involved in the fabrication process, which means cheaper overall material cost for the end user. Light gauge trusses will not warp, rot or split. Metal trusses really are the future of truss reliant building
