<p>A combination board or plate suitable for false floors, wall surfaces or roofs is formed from an integral body using an extrusion molding method after plastic material is made to cover metal strips 11. The board is provided with a flat surface 12, one side of which protrudes forward to form a C pocket 13, and the position of the C pocket is lower than the flat surface; moreover, a bottom portion of the C pocket is provided with a bottom surface 14. The side opposite the C pocket protrudes downward to form a J column 16 which can connect with the corresponding C pocket of another board. The board may be provided with non-slip mats 20 and may have reinforcement ribs (18, Figure 3) on the bottom portion of the board.</p> |
