China's annual output of 1.8 million tons of steel wire rope in the world's first, steel ropes of the main varieties are as follows:
1.Phosphate coated steel wire rope, steel wire by manganese or zinc-manganese system Phosphate treatment, steel wire abrasion, corrosion and rust resistance ability to jump up comprehensively, phosphide film and lubricating grease composite effect, effectively inhibit the occurrence of micromotor wear, fatigue life is the same structure of the glossy steel wire rope 3 times or so, can be verified by fatigue test fatigue life (personally do the fatigue test is the most credible), is the upgrading products of glossy steel wire rope, but also a substitute for the plating first drawn after a thin zinc layer of zinc plated steel wire rope to use (can be tested or compared to the ability of corrosion resistance through the salt spray test) (can be tested by salt spray test or comparison of corrosion resistance).
2. Galvanized steel wire rope, including hot-dip galvanized and electro-galvanized two kinds of zinc, in general, hot-dip galvanized zinc layer is thick, electro-galvanized zinc layer is thin
3. Stainless steel wire rope, 304 or 316 stainless steel is the main, corrosion-resistant effect is very good but the price is expensive
4. Plastic coated steel wire rope, carbon steel wire rope based on the outer layer of polyethylene, polypropylene, or nylon
5.5. Glossy steel wire rope, the market demand has decreased dramatically, will be fully replaced by phosphate coated steel wire rope.
