Light gage steel trusses have been used for 20 or more years. Truss configurations are similar to those built of conventional steel (but with lighter loading) and those built of wood (with comparable loading).
Light gage steel trusses generally are used for roof construction, and as such fit the same niche as light wood trusses: single family dwellings, apartment complexes, retirement villages, small offices, schools and
churches. The trend toward fire resistant construction in many types of
buildings is currently giving steel an advantage over wood. The truss usually
is spaced at 16" or 24".

I wonder of the cost difference... steel vs wood ?
