▁board ▁are ▁normally ▁aligned ▁into ▁the ▁strong est ▁direction ▁of ▁the ▁board . ▁Ar rows ▁on ▁the ▁product ▁will ▁often ▁identify ▁the ▁strong est ▁direction ▁of ▁the ▁board ▁( the ▁height , ▁or ▁longest ▁dimension , ▁in ▁most ▁cases ). ▁Produ ced ▁in ▁huge , ▁continuous ▁m ats , ▁O SB ▁is ▁a ▁solid ▁panel ▁product ▁of ▁consistent ▁quality ▁with ▁no ▁la ps , ▁g aps ▁or ▁void s . ▁ ▁O SB ▁is ▁delivered ▁in ▁various ▁dimensions , ▁strength s ▁and ▁levels ▁of ▁water ▁resistance . ▁ ▁L amin ated ▁tim ber ▁G lu ed ▁l amin ated ▁tim ber ▁( gl ul am ) ▁is ▁composed ▁of ▁several ▁layers ▁of ▁dimensional ▁tim ber ▁gl ued ▁together ▁with ▁mo ist ure - res istant ▁ad hes ives , ▁creating ▁a ▁large , ▁strong , ▁struct ural ▁member ▁that ▁can ▁be ▁used ▁as ▁vertical ▁columns ▁or ▁horizontal ▁be ams . ▁Gl ul am ▁can ▁also ▁be ▁produced ▁in ▁cur ved ▁shapes , ▁offering ▁extensive ▁design ▁flex ibility . ▁ ▁L amin ated ▁v ene er ▁L amin ated ▁v ene er ▁l umber ▁( L V L ) ▁is ▁produced ▁by ▁bond ing ▁thin ▁wood ▁v ene ers ▁together ▁in ▁a ▁large ▁b illet . ▁The ▁gra in ▁of ▁all ▁v ene ers ▁in ▁the ▁L V L ▁b illet ▁is ▁parallel ▁to ▁the ▁long ▁direction . ▁The ▁resulting ▁product ▁features ▁en hanced ▁mechanical ▁properties ▁and ▁dimensional ▁stability ▁that ▁offer ▁a ▁bro ader ▁range ▁in ▁product ▁width , ▁depth ▁and ▁length ▁than ▁conventional
