Description: This huge 12,000 sq. ft. truss system is powerful, yet very graceful. Each of the seven trusses span 100 ft. with a free span of 40 ft. in the middle. To help carry the weight of this massive roof system, steel I-beams were used for the walls. To further provide strength and safety, the joinery in this frame uses a combination of traditional wooden peg joinery, laminate splines and steel pins.
