Note: Above Load Tables Are Based on:
* Uniformly distributed load
* Design in accordance with CSA specification S136
* Material to ASTM A446 grade B minimum yield point 255 Mpa (37000PSI)
* Figures in row "S" denote total loading for allowable working stress
* Figures in row "D" denote total loading for allowable deflection of 1/180th of span
* Heavier loads can be met by custom forming of panel rib depths (subject to engineering)
* The intent of this data is to aid in the preliminary design and estimating for building requirements
* Other factors, including local and regional building codes must also be met
