Truss Spacing For Metal Roof

This is most likely the standard size that you will find on pre made roof trusses.

Truss spacing for metal roof.

For instance if you are spacing your trusses 18 inches apart make a mark 18 inches from the edge. 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. 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.

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. Their defense is our engineers will not allow us to. These standards are as follows. 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.

I ve had roof truss manufacturers try to convince me it is impossible to place wood trusses at spacings of over every 4 feet. 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. 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. 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.
