With the continuous emergence of new architectural forms, exposed to the natural environment of steel or cable structure of increasing, so the market needs a corrosion degree is high, can overcome the adverse effects on the construction of the external environment, relatively beautiful shape a new type of coating material, so Galfan coating arises at the historic moment. Foreign research and development of 95%ZN, 5%AL, mixed rare earth alloy as a new type of steel anti-corrosion coating. Its characteristic is better than that of hot dip galvanized coating. Anti corrosion capacity is 2-3 times the general hot dip galvanized, so it is widely used in steel structure curtain wall and other fields, to achieve the surface after the use of green gray.
PE cable (HDPE) with high density and high density polyethylene material, has the characteristics of good anticorrosion performance. General use of parallel wire or twisted steel wire cable PE, mainly used for steel structure bridge or curtain wall. This process needs to be manufactured in a factory after the coiled plate, with large transportation equipment will become the disk cable transported to the construction site.
For these two kinds of cables, each has its advantages and disadvantages. High vanadium cable production process compared with the PE cable simple, but appearance and the antiseptic age is slightly lower than that of PE cable, PE cable system is slightly complicated, especially, the need for the installation of cable clamp PE cable body sometimes need to divest, such as surface water repellent treatment not when will cause internal oxidation and transport cable need to be wrapped protection against man-made damage. PE reached the life after surface cracks in aging.
Based on the above features, the user can choose the application according to the actual condition!
