1. A closure member of a preferred configuration, comprising:
a board having a major axis and two panels sandwiching a hollow interior that is partitioned by a plurality of ribs positioned at intervals therein, the hollow interior is delimited in a first direction by a pair of opposite end walls, wherein the hollow interior is accessible in a second direction which is substantially traverse to the first direction, and at least one of the two panels is textured during the formation of the board to form a textured outer surface of the closure member; optionally, the pair of opposite end walls forms the left and right side walls of the closure member; optionally, the hollow interior is closed off in the second direction by a cover; optionally, the cover includes an insertion insertable into the hollow interior of the board; optionally, the panels, the ribs and the opposite end walls are formed by extrusion. optionally, the panels, the ribs and the opposite end walls are integrally formed as one piece; optionally, the hollow interior is filled with a preferred reinforcement means; optionally, the hollow interior is partitioned at intervals to form discrete elongate spaces that extends along the major axis; optionally, the insertion is insertable into an end portion of the discrete elongate space to prevent access to the hollow interior. |
