註釋Glued lumber decking panels fabricated with Grade 3 Common faces and 4 Common cores are as stiff or stiffer than conventional panelized decking designed for 4-foot spans. Only panels fabricated with Grade 1 and 2 Clear faces can be thinner or span a greater joist spacing than those with 3 Common faces and 4 Common cores.
