Two new lines of deep I-joists from Boise Cascade are designed for environmentally friendly light commercial construction.
The BCI 90e series and AllJoist AJS-30 series reportedly have higher design values to handle higher loads and longer spans, up to 44'.
Both are available in depths of 18", 20", 22", and 24", with 1-1/2" deep and 3-1/2" wide Versa-Lam LVL flanges in lengths up to 48'.
