Steel Roof Truss Configurations

Roof trusses are on a 4 12 pitch and lean to trusses are on a 2 12 pitch.

Steel roof truss configurations. Truss configurations the framing the american dream study suggests that install ing roof trusses wall panels or floor trusses completes the task of framing in less time requires less framer skill and experience uses less material and ultimately results in a more reliable structure. Since 1950 the manufacturing efficiency of steel trusses has improved dramatically driving down costs and increasing versatility. Total load psf duration factor live load psf roof type 55 1 15 40 snow shingle 55 1 15 30 snow tile 47 30 snow 40 20 snow 1 25 20. 12 50 a foot up to 20 14 95 a foot over 20 we stock 24 30 and 40 gable trusses and 12 lean to trusses.

The open web design as used in steel roof trusses vertical towers and steel floor trusses demonstrate an incredible variety of design applications fulfilling almost any architectural need in modern building and bridge construction. The shapes and spans shown here represent only a fraction of the millions of designs produced by alpine engineers. Custom overhang and pitches are available for additional charges shown below. In the late 1950 s redbuilt s founders invented an innovative composite steel and engineered wood open web truss.

The chord size and web configuration are determined by span load and spacing. All trusses come with a 1 overhang. The pitched or common truss is characterized by its triangular shape. 12 50 a foot 12 40 14 95 a foot 42 60 all lean to shed trusses 1 12 pitch.

Some common trusses are named according to their web configuration such as the king post fan fink or howe truss. All trusses come with necessary nuts and bolts to assemble. Alpine truss designs are engineered to meet specific span configuration and load conditions. 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.

All come with 16 overhang past post. While this article focuses on configurations we also have a very cool set of illustrations showcasing the different parts anatomy of roof trusses. 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.
