compound roof arch

Compound Arch Systems

Compound Roof Systems are an evolution of using two sets of truss elements to create the capacity of one much larger unit. By using a flat grid truss, structurally tied to an arched truss, then much longer spans are achievable whilst maintaining large loading capacities.

Compound Roof Systems are an evolution of using two sets of truss elements to create the capacity of one much larger unit. By using a flat grid truss, structurally tied to an arched truss, then much longer spans are achievable whilst maintaining large loading capacities. Each compound arch is joined to the next via a series of tubular purlins. With most of the components being standard trusses along with any of the special components being relatively small sections, this provides for an extremely tight truck pack.
