What is rafting?
Rafting is a process where the contractor uses complete trusses to assemble an entire section of a roof on the ground, and then lifts the completed assembly onto the building structure. On many jobs, rafting allows most of the roof framing and decking to be assembled on the ground, without the need for multiple lifts, scaffolding, and minimal or no fall protection. Mechanical systems can also be installed within the rafted roof assembly while it is at ground level.
Why are so many contractors rafting roofs with TrusSteel?
Because TrusSteel trusses are light in weight (up to one-half the weight of trusses made from wood or "C" channel materials), you can assemble a significant roof section on the ground and still lift it with an average crane. With the exceptional lateral stability (stiffness) of TrusSteel trusses, you can build a roof assembly that will survive a lift without introducing a lot of extra bracing.
What assures a safe rafting experience?
Rafts of trusses, no matter the brand or type, must be engineered so that they will lift safely and without damaging the trusses. The engineers with BBD Engineering and Design are experts in designing rafts and lifting (or "pick") points.
