<br />Example:
<br />For 2" x 4" x 0.055" x 0.120" Self Mating Beam;
<br />Span between uprights use load width to enter table,
<br />For 12' Roof Panel + 2' overhang, load width = LW; LW + 12' I 2 + 2' a.H. = 8'
<br />Enter table on left at 8' and read allowable span under required load;
<br />Thus for 100 M.P.H. wind load I live load or 18 1# I Sq. Ft and Load Width = 8'
<br />Maximum Beam Span for 2" x 4" x 0.055" x 0.120" = I I I -v I
