The corrosive media in the environment, such as water, gas and salt, can enter into the concrete through infiltration and diffusion, causing corrosion and deterioration of the concrete and corrosion of the steel reinforcement.

In accordance with the steel viaduct is in a relatively severe industrial and marine atmospheric corrosive environment with a service life of 100 years, the design of the anti-corrosion coating programme requires a protection life of more than 50 years.

It is suitable for the initial coating of steel structures such as bridges (including ancillary structures) of railway steel bridges, as well as the re-coating of steel bridges after the deterioration of the coating film and maintenance coating.

The application of coatings to new energy vehicles transcends mere aesthetics; it is intricately intertwined with the vehicle's corrosion resistance. This elaborate process entails the meticulous layering of primer, basecoat, and clearcoat, each serving to bolster both the durability against corrosion and the visual allure. Eco-friendly waterborne paints, distinguished by their thinner films, necessitate stringent environmental conditions during application, rendering the entire endeavor a sophisticated amalgamation of technology, artistry, and environmental stewardship.

The mechanical equipment is widely utilized in diverse fields, including national defense construction, transportation infrastructure, energy industry development, raw material industries such as mining, agricultural and forestry water conservancy, urban construction, and environmental protection.

Special containers, or non-standard containers, are designed and manufactured according to specific usage requirements. Currently, the types that are rapidly developing mainly include sewage treatment containers, hard bulk cargo containers, offshore equipment containers, aquaculture containers, energy storage equipment containers, and special shelters. The need for corrosion protection of these special containers stems primarily from the harshness of their operating environments, the high standards for corrosion resistance, and the demand for personalized aesthetic appeal.

The coatings and coating technologies used in high-speed trains and subway systems belong to the categories with higher technical thresholds in industrial coatings. Most train carriages are manufactured using lightweight aluminum alloy materials. The coating process is categorized into new construction and factory repair, and the coated areas typically include the exterior surface, interior surface, underbody, bogies, and other components.
