An engineered wood fence picket and system for manufacturing fence pickets using engineered wood products, including, but not limited to, oriented-strand board (OSB), laminated veneer lumber (LVL), fiber strand, and/or laminated strand lumber (LSL). The opposing right and left edges of each picket has corresponding elements of a joint, such as, but not limited to, a shiplap joint or tongue-and-groove joint. A fence or fence segment may be constructed by aligning a plurality of said fence pickets vertically or horizontally so that the edges of adjacent pickets mate or meet to form a joint. The fence can be assembled more quickly and cheaply than with any prior art materials, and the fence will be higher quality, with longer life, thinner and lighter, and minimal maintenance.
