Wave beam guardrails are typically treated with electrostatic powder coating for corrosion protection. Electrostatic powder coating, or simply powder coating, utilizes static electricity to evenly apply powder onto the wave beam guardrail. This process does not require any solvents, making it environmentally friendly and harmless to humans. The powder is then cured under high temperatures, creating a seamless bond with the metal surface, offering superior corrosion resistance compared to other methods like painting.
Before powder coating, the wave beam guardrails undergo a thorough cleaning process to ensure proper adhesion. After the powder is electrostatically applied, it is cured in a high-temperature curing line, completing the powder coating process.
Wave beam guardrails are installed outdoors and are exposed to harsh environmental conditions, including sunlight, wind, and rain. If the corrosion resistance is inadequate, even relatively new guardrails can suffer from cracking, rusting, and other problems, leading to an unsightly appearance and affecting the overall visual appeal of the roadway.
Electrostatic powder-coated guardrails offer significantly enhanced corrosion resistance compared to untreated wave beam guardrails. This superior corrosion protection stems from a specialized anti-corrosion process incorporated in the manufacturing process. The powder-coated surface utilizes a full polyester powder coating, while the inner layer employs hot-dip galvanization. This combination, achieved through electrostatic spraying and a strong bond with the base material, ensures exceptional corrosion resistance for the wave beam guardrails.
Apart from its exceptional corrosion resistance, powder-coated wave beam guardrails also excel in high and low temperature resistance. They are designed to withstand prolonged exposure to direct sunlight and high temperatures without exhibiting problems like blistering, wrinkling, or peeling.
Besides the performance advantages, powder-coated wave beam guardrails also offer aesthetic benefits. The application of colors such as green enhances the overall appearance, adding a touch of vibrancy to monotonous roadways. This visual appeal contributes to a more pleasing aesthetic, while simultaneously enhancing vehicle safety.
