A channel structure for a channel sign is provided to decrease damage to a human being by using a light synthetic resin. A channel sign is formed by bending or curving a channel to form a target pattern. The channel includes a side frame(10) and a closure frame unit(20). The side frame is made of a synthetic resin and arranged in plural rows on an implementation surface, so that a space is formed. The closure frame unit is coupled with the side frame and encloses the space between the side frames. The closure frame unit includes a frame member(21) and a closure plate(22). The frame member is formed by extruding a synthetic resin. A metallic bending core member(23) is inserted into the frame member, so that the metallic bending core member is bent or curved. A coupling portion(24) is protruded on the bent or curved inner surface. An outer end of the closure plate is fixed on the coupling portion, when the frame member is curved or bent in a desired shape, so that the space between the side frames is closed. |
