Guardrail Anti-rust Technology-Good machines and tools can improve work efficiency
Workers put the guardrail to be painted into a boiling-like container filled with paint. This unique coloring method is called dipping. It is more durable than direct painting and has a good anti-corrosion effect.

‌Powder dipping technology‌: This technology originated from the fluidized bed method. The fluidized bed was originally used for petroleum contact decomposition, and was later improved for metal coating. In the fluidized bed, the powder coating is added to a porous and breathable container at the bottom, and the treated compressed air is sent in through a blower to make it reach a "fluidized state" to form a uniformly distributed fine powder. ‌

‌Coating process‌: The workpiece is first degreased and preheated, and when the temperature reaches above the melting point of the powder coating, it is immersed in the fluidized bed. In this process, the plastic powder will adhere evenly to the workpiece. Subsequently, after plasticization, polymer cross-linking and leveling, a steel-plastic composite product is finally formed.
