You know a truss is a new of built-up structural member which they can use in place of a specific girder or grin. Trusses are made from a multitude of straight marketers (generally made from wood or metal) arranged in triangles. This design allows a truss to span a very long distance without intermediate support; most of them are more suitable to large, heavy girders because of their low cost and easy implementation. For large construction projects, the design and fabrication of roof trusses are supposed to be handled by licensed engineers. However, for smaller activities, you can make roof trusses upper body up in accordance with your project's needs.Now,follow this step :


1、Design your roof truss。2、The best material for building trusses on a small scale project is sawn lumber.3、The roof truss will have a horizontal lower chord, and 2 angled upper chords that follow the roof line. 4、 Saw the truss members to size. After designing the truss, saw each member to its required length. 5、 Lay the truss members out on the ground. Once all the chord and web members are cut to size, arrange them flat on the ground in the shape of the truss.6、Secure the joints with metal gusset plates. 7、As an alternative, you can make your own gusset plates out of plywood. 8、 Install the roof trusses. Once the trusses are constructed, lift them into place and set them onto the top plates of the exterior walls just as you would a beam or joist.




Accommodate the roof trusses. Once the trusses are planned, lift these things into place and set them onto the top plates of the external area walls just as you would a beam or joist. Toe-nail them into the top meal to secure them, and then cause them to become braced laterally using clogging or long purlins.
