Design and Manufacturing

Pictured is one of fourteen heavy trusses that puts the scale of this project into perspective (notice the men under the truss, inside the red circle). This project was extremely challenging from engineering to design to fabrication and shipping. This is the type of project that separates National Lumber and Reliable Truss from the rest of the competition.
