請問什麼是Marine-grade plywood ?

Marine-grade plywood is made entirely of Douglas-fir or Western Larch. The

grade of all plies of veneer is B or better. B-grade veneer may have knots

but no knotholes. A-grade veneer has no knots or knotholes. Both A and B

grade may contain wood or synthetic patches. Panels are sanded on both faces

or Medium Density Overlay (MDO) or High Density Overlay (HDO). The maximum

core-gap size permitted is 1/8 inch. Its exposure durability rating is

EXTERIOR and the glue used is a fully waterproof structural adhesive

請問這是什麼樣的木板? 跟一般三合板有什麼不同?

60 cm x 60 cm x 2.5 cm的板一般價格大概是多少?

感謝~~

    Plywood就是合板, 這塊合板適合造船(Marine-grade), 或室外(Exterior)用. 強調它的材質(每一層都是B級以上, 無節孔), 耐天候(內部最大間隙1/8吋), 用防水膠高壓(MDO, HDO)壓製成.

    這種合板我沒買過, 通常木材行買的到最大厚度只有1.8cm, 而且是室內用的. 不過我只是個業餘DIY愛好者, 所知有限.
