*Table values are conservative for B30 and BR30; individual tables available on request. Section properties shown are for C36 & R.
The maximum spans shown in this table are based on a limiting deflection of L/180 or a limiting stress of 26.700 psi. Subgirt spacing is not to exceed 4' o.c. When practical, subgirts should be placed over a girt line, CFA-FL and SS18 can also be used as liner panels; call for span information. The tables cover either positive or negative wind pressures.
