Steel roof truss configurations.

The chord size and web configuration are determined by span load and spacing. All trusses come with necessary nuts and bolts to assemble. Custom overhang and pitches are available for additional charges shown below. The shapes and spans shown here represent only a fraction of the millions of designs produced by alpine engineers.

While this article focuses on configurations we also have a very cool set of illustrations showcasing the different parts anatomy of roof trusses. Just as there are many types of roofs with many roof parts there are many different types of roof trusses this extensive article explains through a series of custom truss diagrams the different truss configurations you can use for various roofs.

The pitched or common truss is characterized by its triangular shape. Since then this design solution for architects and engineers has evolved to support large floor areas and large roof spaces of up to and over 100 feet wide.
