Load tables on pages B-200–B-210 for A, B, C, E and H series channel are for single span beams supported at
the ends. These can be used in the majority of cases. There are times when it is necessary to know what happens
with other loading and support conditions. Some common arrangements are shown in Table 6. Simply multiply the
loads from the Design Load Tables times the factors given in Table 6. Examples shown on page B-214.
