Surface treatments for guardrails include galvanizing, spraying plastic, and dipping plastic.

Powder coating products are commonly used indoors, while immersion coating products are typically used outdoors, with immersion coating being more costly. The material has the characteristic of softening when heated and then solidifying into a film upon cooling, primarily through a physical melting and plasticizing process to form the coating.

In the plastic coating process, the majority utilizes thermoplastic plastic powder, primarily for applications such as highway guardrails, railway guardrails, zinc steel fences, balcony railings, PVC fences, perimeter fences, fences, airport guardrails, garden guardrails, community guardrails, villa guardrails, residential safety nets, metal craft racks, cages, and sports fitness equipment.

Our electrostatic powder coating products are based on steel substrates with a weather-resistant high molecular weight resin outer layer (thickness of 0.5-1.0mm), offering features such as anti-corrosion, rust prevention, resistance to acids and alkalis, moisture-proof, insulation, aging resistance, good tactile feel, environmental friendliness, and long lifespan. They are a replacement for traditional coatings like paint and galvanizing, with a wide range of applications.
