China's aluminum alloy cable bridge industry cost has been effectively controlled

In recent years, with the prosperity of the domestic economy, the improvement of production technology, China's FRP cable bridge continue to adopt new technologies, new equipment, and actively adapt to the needs of market development, has developed a cascade, tray, trough, modular cable tray The With the advantages of corrosion resistance, easy installation and long service life, it is favored by many construction units and purchasing personnel. It is widely used in petroleum, chemical industry, electric power, light industry, TV, telecommunication and so on.
 
The FRP cable bridge by the trough, tray or cascade of the straight line, bending, three links, four-way components and arm, hanger, etc., over the years FRP cable manufacturers keep up with market trends, according to the use of different areas Requirements, has developed the following bridge, to meet the needs of the market.
 
As we all know, the general environment, the choice of steel cable bridge; corrosive environment, the general use of aluminum alloy cable tray or FRP cable tray; fire hazard environment, the choice of flame-retardant bridge or fire bridge.
 
In the same specifications, aluminum alloy cable bridge than the steel cable bridge 20% more expensive; life is more than 5 steel cable bridge; the quality of steel cable bridge about 1/4. In the same specifications, glass fiber reinforced plastic cable bridge than steel cable bridge 3 times; life is more than 5 times the steel cable bridge; the quality of steel cable bridge about 1/2. In the same specifications, the flame retardant cable bridge than the steel cable bridge 2.2 times; life is more than 5 times the steel cable bridge; quality than steel cable bridge weight 30%. In the same specifications, the fire-resistant cable bridge is slightly more expensive than the steel cable tray; life is more than 3 times the steel cable bridge; quality and steel cable bridge is basically the same.
 
But after years of reform, the brutal competition of China's bridge industry has promoted the integration of the industry, and the cost control of the bridge has been well controlled. But in this round of competition, all and large-scale production, the development of new products such as bridge. These technology troughs will be the bottleneck of the long-term constraints of the industry's long-term profitable ladder bridge capacity and the ability to participate in international competition, the industry can only fall into low-cost cable competition is often unfavorable. At the same time as the industrial chain value-added capacity decreased year by year, will lead to more and more capital withdrawal bridge from the bridge industry chain is more fragile.
 
Over the past few years the bridge industry profitability is poor, mainly due to relative excess capacity. With the advancement of the bridge, the demand for the bridge is growing rapidly. However, since 2007, the bridge industry supply and demand improved. At present, the demand for the bridge is strong, the utilization rate of the main cable bridge is greatly improved. In the future, with the development of the bridge, the demand for the bridge will continue to maintain a rapid growth, the average annual growth rate is expected to be more than 20%.
