The present invention relates to a lattice for a crime-preventing window. The crime-preventing lattice for a crime-preventing window, which has circular pipes installed vertically at regular intervals so that the upper and lower ends of the circular pipes composed of aluminum can be inserted and fixed into upper and lower fixed frames installed and fixed to a crime-preventing window, has multiple main crime-preventing lattices installed vertically at regular intervals thereon. The multiple main crime-preventing lattices comprise: circular pipes formed of aluminum; inserting protrusion parts at both sides protruding symmetrically so that insertion grooves on the inner surface of the circular pipes can face each other; assembling protrusion parts at both sides protruding symmetrically toward the inside of the circular pipes to intersect with the inserting protrusion parts at both sides at right angles, having the inside closed, and opened outward; and a reinforcing iron core composed of a steel material with a thickness such that both ends can be inserted tightly into the assembly grooves of the inserting protrusion parts at both sides inside the circular pipes. |
