When customers choose outdoor fiberglass cooling towers, the corrosion resistance and service life of the cooling towers are the most critical. In addition, the work of cooling towers generates moist heat. Obviously, metal materials that are susceptible to oxidation should not be used. Glass fiber reinforced plastic is the only professional choice. Now the cooling tower industry is all hand lay-up production, which relies heavily on labor, the efficiency is very low, and the quality is unstable, which restricts the development of the cooling tower industry. It is recommended that the outer panel of the cooling tower and the side plate of the cooling tower be selected from the FRP sheet produced by mechanized continuous production, which has stable quality and high production efficiency. Products are more cost-effective.
