Is there a time deadline from time of production and installation for a wood truss?
While a time limit is difficult to specify, a good rule of thumb may be one month. Exposure to moisture and the elements of weather does have an impact on this time frame. If any trusses are to be stored long-term they need to be covered with a protective material that allows for air and moisture to circulate around them. The material should not allow moisture to collect on the trusses. Trusses should also be kept off the ground and blocking placed under the trusses at regular intervals.
