Roof trusses design standards. Common or standard trusses are symmetrical and have standard four inch heels. Tpi is connecting the tru. The standard roof truss spacing is 2. Every truss is made to meet unique design specifications engineered to support the specific loads placed upon them.

Wood trusses used in specialized applications such as agricultural and commercial buildings provide spans exceeding 25m 80. Almost all residential trusses use this spacing. Our manufacturing process makes the most efficient use of timber and ensures minimal timber wastage. These standards are as follows.

Metal plate connected trusses are used to create arches of all types. As a testament to their strength wood trusses are used in concrete formwork. To achieve maximum indicated spans trusses may require six or more panels. Girder trusses are designed to carry additional loads other than standard roof loads.

Boards may be reduced slightly. Trusses must be designed for any special loading such as concentrated loads from hanging partitions or air conditioning units and snow loads caused by driftingnearparapetorslide offfromhigherroofs.

Typical roof truss spacing means that they are usually about 24 inches from centre which means at the centre of one truss there will be a two foot gap or twenty four inch gap until the centre of the next truss.
