<p><P>PROBLEM TO BE SOLVED: To provide a mounting frame for wiring accessories which does not contain chromium and has excellent rust preventability, processability, and productivity. <P>SOLUTION: In the mounting frame 1 for wiring accessories used to arrange the wiring accessories 2 on an erection surface, the mounting frame 1 is made by molding chromium free fused zinc-plated steel material. Hereby, the occurrence of red rust of the mounting frame 1 is suppressed, and also in general it has corrosion resistance equivalent to steel material where a conventional zinc-chromate-plated film is made. Moreover, a cut end face is given high rust preventability, and after processing of the fused zinc-plated steel plate, the necessity to apply plating treatment is eliminated. <P>COPYRIGHT: (C)2004,JPO</p> |
