At present, most of China's grid structure using plate grid structure. Protection of steel structures assumed life under harsh conditions for 20 years hanging rack, Zn or Al thermal spray coating life of 20-year terms; organic paint coating to three-year terms, require the construction of nearly 20 years, seven times, and temporarily Excluding other losses caused by construction, for example, and other business downtime. So grid work, available grid, thermal spray coating Al or Zn comprehensive pricing is: 4 to 6 yuan / year · m2, an average of 5 yuan / year · m2; and organic paints and coatings for 1.7-27 yuan / year · m2, an average of 14.35 yuan / year · m2, about three times the long-term preservation of thermal spray technology.
