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, wire rope core. The stronger the wire rope core is, the heavier the specific gravity is, the better the support force of the outer layer of the wire rope is, and the better the wire rope quality;
3. Materials. The material is the steel number and strength. The higher the steel number, the better the quality of the steel wire with higher strength;
4. The quality of the loose rope is good after the rope is cut, and the quality of the wire rope with a relatively long lay length is better than the short lay length;
5, 316 stainless steel wire rope anti-corrosion ability is stronger than 306 stainless steel wire rope anti-corrosion ability, 306 than hot-dip galvanized steel wire rope anti-corrosion ability, hot-dip galvanizing is better than electro-galvanized steel wire rope; nylon coated plastic wire rope quality is stronger than PE plastic coated steel wire rope, PE package The plastic steel wire rope is better than the PVC plastic coated steel wire rope, and the plastic coating has stronger anti-corrosion ability than the galvanized steel wire rope.
