Truss Spacing For Metal Roof

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.

Truss spacing for metal roof.

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. 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. Their defense is our engineers will not allow us to. 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.

For instance if you are spacing your trusses 18 inches apart make a mark 18 inches from the edge. Engineers have since determined however that the physical design of a post frame building will allow for standard spacing as great as 12 feet from the center when using high quality metal connector plates and lumber. Typical standard the typical standard for the spacing on the roof trusses is 24 inches. Roof trusses were usually produced on site in the past.

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. 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. This is most likely the standard size that you will find on pre made roof trusses. I ve had roof truss manufacturers try to convince me it is impossible to place wood trusses at spacings of over every 4 feet.
