Commonly Used Cover Forms
Stainless steel frame + PC endurance plate
Characteristics：
Impact resistance, light weight, high tensile strength, tough and safe.
Good weather resistance, ultraviolet resistance, excellent lighting, and long service life.
The overall design is beautiful and economical.
Precast fiberglass cover plate
Characteristics：
With arc shape it can meet the stress requirements without skeleton.
Light weight overall.
The whole production forms in the factory , so it will be easy installation without on-site production.
It can be hoisted directly, in other words, be fixed after positioning.
Reverse hanging membrane
Characteristics：
Protect steel structure from corrosion caused by contact between corrosive gas and it.
The steel structure may have a over 30-year service life.
Membrane material has the advantages of light weight and tensile strength, so that it is suitable for large span pool body.
The shape seems elegant and beautiful, and the pretty look will maintain a long time.

Common forms of air distribution
FRP Duct
Characteristics：
With excellent anticorrosive property, it can prevent acid, base, organic solvents and other media corrosion.
Light weight, high strength, convenient transportation and loading, further more, easy to install.
The smooth surface can reduce flow resistance, improve flow rate and reduce energy consumption.
Stainless Steel Duct
Characteristics：
The appearance is beautiful overall. And the inner wall is so smooth that there is little resistance. In addition the gas tightness is good and the bearing strength is high.
It is easy to maintain integrally for it built with solid material.
Can be transported and adjust on-site expediently.
Galvanized Steel Duct
Characteristics：
Great fire-proof
High compressive strength and strong resistance to static pressure
It is convenient to produce on-site as well as carry, while not easy to be damaged by collisions.
