Project Background
Client Background: The client is a large-scale municipal engineering supplier in South America, primarily producing road guardrails, streetlight poles, and public transportation metal facilities for urban infrastructure projects.
Client Issues: Due to the long-term exposure of their products to the outdoor environment, the client has extremely stringent requirements for the coating's weather resistance, corrosion resistance, and long-term stability.
Client Needs
The client raised the following core requirements at the beginning of the project:1. Enhance long-term outdoor corrosion resistance (rain, humid environments)
2. Enhance UV resistance to prevent fading and chalking
3. Improve coating thickness uniformity and adhesion
4. Adapt to the spraying needs of large-size metal structural components
5. Reduce later maintenance and rework costs
Our System Solution
For outdoor infrastructure applications, we provided a dedicated powder coating solution:Recommended high-weather-resistant outdoor-grade polyester powder coating system
Optimized electrostatic spraying parameters to improve the uniformity of large metal coverage
Strengthened adhesion to corners and welded structural areas
Provided optimization suggestions for curing processes to ensure long-term stability
Support for a hybrid manual + automatic spraying process
Project Results
Significantly enhanced outdoor weather resistance, adapting to long-term exposure environments
Improved corrosion resistance, reducing rust problems
More uniform and robust coating with enhanced adhesion
Improved product appearance quality, meeting municipal engineering standards
Significantly reduced maintenance costs
