Concrete structure corrosion includes： coastal area, mainly severe salt spray corrosion of the marine atmosphere; inland river area, the main corrosion factors are freeze-thaw damage, carbonation, erosion damage and microbial damage, etc.; industrial area, the main corrosion factors are acid rain, salt crystal variation expansion, chloride ion corrosion, carbonation, etc.; high temperature area, due to light and heat, the coating undergoes aging degradation or cross-linking; dry desert area, the main wind erosion damage; municipal bridges are mainly damage caused by carbonisation.

With the passage of time, concrete bridges are gradually faced with such problem as corrosion of reinforcement, carbonisation of concrete, chloride erosion, sulphate erosion and freeze-thaw cycle damage, etc. These problems not only impair the aesthetics, but also weaken the structural strength and safety of bridges. which seriously threaten the safety and smoothness of transport.

Customised solutions for different structural corrosion characteristics and requirements, systematic and professional coating integration.

Focusing on the coating and material matching, according on industry standards, the use of weather-resistant, stain-resistant, anti-icing and other new functional materials.

Formation of professional tooling and process, accumulation of experience attention to detail, professional test means and equipment, professional evaluation system.
