The product can be ordered in four Alljoist profiles including the new deep joist AJS 30 products introduced earlier this year. The Alljoist series engineered wood products are sustainable products that are approximately 35% stronger than dimension lumber joists, while using about 35% less wood fiber, says the maker. The products are also lighter weight, less expensive to ship, easier to handle, and faster to install than dimension lumber joists.
Alljoists have solid-sawn flanges made from black spruce, a denser and stronger wood than traditional species. Alljoist products are available in four different profiles: AJS 140 with 1-1/2” deep, 2-1/2” wide machine stress-rated flanges in both 9-1/2” and 11-7/8” depths; AJS 20, also with 2-1/2” wide flanges in depths of 9-1/2”, 11-7/8”, 14” and 16”; AJS 25 with 3-1/2” wide flanges in 9-1/2”, 11-7/8”, 14” and 16” depths; and the new AJS 30 deep joists with 3-1/2” wide flanges in 18”, 20”, 22” or 24” depths. This means Alljoist products are now available in approximately 2” increments from 9-1/2” up to 24”, for virtually any residential use and many multi-family and light commercial applications.
