Coating Steel Wire Rope

Steel wire ropes are widely used in many areas such as machinery, construction, offshore and marine applications and handrail cables. With wear, loads and the marine environment, steel wire ropes can be easily damaged and corroded. Thus, it is important to protect them with coatings or lubricants for long lasting working life.

The most common way to protect steel wire rope from corrosion and abrasion is by coating it with a specialized corrosion and abrasion resistant coating. Generally, these coatings are either zinc, aluminum, or some combination of the two, depending on the resistance required.

Zinc coated steel wire rope is usually called Galvanized Wire Rope, due to its silver-grey colour. This type of coating is designed to provide the best protection for steel wire ropes under normal service conditions, and is often used in applications where there is no exposure to salts or acids.

Aluminum coated steel wire rope is a good choice for applications requiring high resistance, due to its excellent abrasion and corrosion resistance when exposed to salts and other aggressive environments, including exposure to organic acids, ammonia, and chloride solutions.

As well as offering better corrosion and abrasion protection, coatings can also add extra strength to steel wire rope. For example, a coating that adds 10-15% additional strength can make steel wire rope a much better choice for applications such as mooring, towing, and anchoring.

In addition to providing protection against corrosion and abrasion, coatings can also help prevent the knotting and seizing of steel wire ropes. This is important as knotting and seizing of steel wire ropes can lead to erratic performance, as well as premature failure of the ropes.

Finally, when selecting a coating for steel wire ropes, it is important to consider the environment in which the ropes will be used, as well as the strength requirements. Different types of coatings will offer different levels of protection, depending on the type of environment. Thus, it is important to select a coating that will provide the best protection for the steel wire ropes.

Coating steel wires rope is an important way to improve the overall performance of the steel wire rope. This process is based on the shop system design, by manual cleaning, pre-heat, acid, pickling paint pre-compacted, the initial spraying and spraying, light the drying of hot air after the recovery of a series of systematic and technological process.

Coating steel wire rope surface of the smooth coating, can significantly reduce the friction between the steel wire and increase the load bearing capacity of the steel wire rope. The coating also has the excellent overall performance of heat, electric and acid resistance. In addition, it can reduce the pull force required for various operations, and improve the overall performance of rust, wear and other aspects.

The most common coating method is electroplating, hot-dip galvanizing and spray plastic. The advantages of electroplating layer are good adhesion, firm layer structure, and good overall performance, so the surface of steel wire rope can be directly solidified without further processing. The hot-dip galvanizing layer has higher adhesion, so the steel wire rope with hot-dip galvanizing layer has higher overall performance. The polyester coating layer is mainly composed of polyvinyl chloride, polyurethane and epoxy resin, and is the most practical coating in the steel wire rope.

In actual operation, coating steel wire rope should be considered in many aspects according to the actual situation, and then make a reasonable choice. This can not only improve the performance of steel wire rope, but also improve the safety factor.
