1. 16" and 18" deep beams are limited to two and three piece beams (single members are not permitted).

2. Table values are based on uniform loads and the most restrictive of simple or continuous span. Shaded areas represent load conditions controlled by a continuous span. When properly fastened together, double the table values for two piece beams or triple the values for three piece beams. Reference inside front cover for connection requirements.

3. Beams must be checked for stresses under total load and for deflections for both live load and total load conditions. Design loads must be in accordance with the applicable code. Deflections must not exceed the maximums permitted by the code. If deflection limits other than those on which the tables are based are applicable, beams must be designed using the StrucLam Design Stresses on the inside front cover of this guide.

4. Table values assume continuous lateral support of the compression edge of the beam and lateral support at the ends and all bearing points.

5. Reference the bearing length chart on back of product guide for required bearing length.
