PROBLEM TO BE SOLVED: To use paint without wasting it so as to reduce cost by a simple work which everybody can do without causing uneven coloring and liquid dripping of a ceiling lattice louver, liquid collection in corners, and warping and deformation of a louver member. SOLUTION: Grooves 3 having the width which is larger than the plate thickness t by 0.05 to 0.3mm and the depth which is smaller than a half of a distance H between fringes on both sides by 0.2 to 1.0mm are provided at an equal pitch on one side fringe of a louver member 1 like a rectangular plate on which paint is applied on both front and rear surfaces thereof. A plurality of louver members 1 arranged in parallel at a groove pitch interval oppose to a plurality of louver members 1 which are orthogonal to them to fit the grooves 3 mutually. Bottoms of the grooves 3 are caulked mutually to combine the louver members 1 in the shape of a grid and fix them. |
