The predecessor of Wuxi General Steel Rope should be Wuxi County Wire Rope Factory, which is a local state-owned enterprise. It was later merged by the central enterprise Sinopharm Group and is currently a subsidiary unit of the central enterprise. Its main products are elevator wire ropes and lifting wire ropes. It is only for refer to.
China ranks first in the world with an annual output of 1.8 million tons of steel wire ropes. The main varieties of steel ropes are as follows:
1. Phosphating coated steel wire ropes (patented technology), steel wires treated with manganese or zinc Manganese-based phosphating treatment improves the steel wire's wear resistance, corrosion resistance and rust prevention capabilities. The combined effect of the phosphating film and grease effectively inhibits the occurrence of fretting wear. The fatigue life is about 3 times that of smooth steel wire ropes with the same structure. It can be passed The fatigue test verifies the fatigue life (doing the fatigue test yourself is the most reliable). It is an upgraded product of the smooth steel wire rope. It can also be used as an alternative to galvanized steel wire ropes that are first plated and then pulled out with a thin zinc layer (the salt spray test can be used to check or compare the resistance). erosion ability).
2. Galvanized steel wire rope, including hot-dip galvanizing and electro-galvanizing. Generally speaking, hot-dip galvanizing has a thick zinc layer and electro-galvanizing has a thin zinc layer.
3. Stainless steel Steel wire rope, mainly made of 304 or 316 stainless steel, has excellent anti-corrosion effect but is expensive
4. Plastic-coated steel wire rope, based on carbon steel wire rope, the outer layer is coated with polyethylene, polypropylene or nylon

5. The market demand for smooth steel wire ropes has dropped sharply and will be completely replaced by phosphate-coated steel wire ropes.
6. Steel wire ropes for marine engineering moorings
7. Cable wire ropes
For use in atmospheric environments, phosphating coated steel wire ropes are preferred, and in heavily corrosive environments, heat-resistant wire ropes are preferred. Galvanized-phosphating double-coated steel wire rope, offshore steel wire rope is preferred in sea water. When purchasing, please note that the name of the steel wire rope, such as phosphate-coated steel wire rope or 316 stainless steel wire rope, must be indicated on the purchase invoice to protect your legitimate rights and interests. In addition, patented products generally have a patent number spray-marked on the outer packaging of the steel wire rope. Only For reference
