The end of the steel bar must be straight and the bend must be corrected; the connecting end of the steel bar and the inner wall of the sleeve must not be mixed with oil, rust, and sand. The external grease of the sleeve must be wiped off. 3. The pattern of cold-extruded steel bar joints must not be flattened. 4.
