  • Different from common zinc barbed rope, high zinc barbed rope surface zinc content is very high can reach 6-8 times of the former, so there is a great advantage in the service life, ordinary products begin to corrosion three to five years while the latter will take longer to change. Stainless steel barbed rope is in material protection so durability is also better, these two products are long service life, but in terms of high price.

  • The material of steel structure will affect the organization and thickness of hot dip galvanized film. For example, high tension steel containing silicon, carbon content is high, easy to react with molten zinc quickly, the result of excessive growth of alloying, will cause a grayish black appearance, but does not affect its corrosion resistance. Or heat treated steel, if its tensile strength exceeds 90kg/mm2, after hot dip operation, easy to reduce its strength, etc.

  • When a guided weight progress or repeated guided weight progress at a smaller height (driving) or left-handed and right-handed rope is used in pairs, ordinary wire rope can be selected. The determination of wire rope rotation should comply with: right-handed rope groove drum recommended use of left-handed wire rope: on the contrary, left-handed rope groove drum should use right-handed wire rope.

  • Although galvanized iron wire has the protection of galvanized layer, it does not say that it will not rust at all, but delays the time of rust. In general, cold galvanized iron wire can be kept for 1-2 years without rust, hot galvanized iron wire can be used for 8-10 years without rust. If properly maintained, the use time will be longer. So how to prevent galvanized iron wire rust?

  • The life of the “wire”, is actually “low carbon steel wire”, carbon content in less than 0.2%. The surface is usually coated with zinc plating because it is easy to rust. Under atmospheric conditions, the galvanized layer will not rust before most of the fall off, relatively soft. The life of the “steel wire”, is carbon content in about 0.6% of the “carbon steel wire”, or carbon content in about 0.8% of the “high carbon steel wire”, they have enough hardness and elasticity after appropriate heat treatment, high strength. Uses such as winding ordinary spring and so on.
