Our steel trusses are made out of a true 2" x 2" angle and are 15" tall.
They also have a 15" overhang past the end of each post.
They come in a variety of lengths and can be gable trusses (4/12 pitch) or lean-to trusses (1/12 pitch).
They come with the brackets welded on to fit 2" x 6" wood purlins.
We use 29 gauge residential metal for the roof and sides.
Although we do not provide the lumber, we recommend using 6" x 6" posts and 2" x 6" purlins.
HOW TO MEASURE:
For gable trusses, the measurement is pulled from the outside of each post.
For lean-to trusses, you will measure from the wall that it is being installed against to the outside of the other post.
