Truss Spacing For Metal Roof

These standards are as follows.

Truss spacing for metal roof.

After the braces are in place you will mark the distance from the edge of the building to where you would like to attach your first truss. Typical standard the typical standard for the spacing on the roof trusses is 24 inches. Flat the most economical flat truss for a roof is provided when the depth of the truss in inches is approximately equal to 7 of the span in inches. With this design change roof trusses could be placed 12 feet apart making it possible for roofs to support the loads to which they would be subjected.

Just keep in mind that if the length of the board size is more than 20 feet then you need to use a more expensive type of lvl board and not a traditional pine board for this longer length. This is most likely the standard size that you will find on pre made roof trusses. Their defense is our engineers will not allow us to. 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.

As most building these days are using those pre made trusses on the roof 24 inches become the main size for any roofing construction when it comes to its truss installation. Depending on the complexity of your free computational tool it may require you to enter details about rafter spacing usually 16 on center bridge type height and board size. I ve had roof truss manufacturers try to convince me it is impossible to place wood trusses at spacings of over every 4 feet. Most economical when the difference in slope between the top and bottom chords is at least 3 12 or the bottom chord pitch is no more than half the top chord pitch.
