1. Specific gravity. The diameter of the wire rope is the same, the heavier the specific gravity, the better the quality of the wire rope;
2. Steel wire rope core. The stronger the core of the wire rope, the heavier the specific gravity, the better the support for the outer strands of the wire rope, and the better the quality of the wire rope;
3. Materials. The material is the steel grade and strength. The higher the steel number, the better the quality of the wire rope with higher strength;
4. After the rope is cut, the slightly loose quality is good, and the quality of the wire rope with a relatively long lay length is better than that with a short lay length;
5. The anti-corrosion ability of 316 stainless steel wire rope is stronger than that of 306 stainless steel wire rope. The quality of plastic wire rope is better than that of PVC plastic coated wire rope, and the anti-corrosion ability of plastic coated wire rope is stronger than that of galvanized wire rope.
