The difference between galvanized highway guardrail and sprayed highway guardrail
Hot-dip galvanizing: It is an effective metal anti-corrosion method. It is to make the zinc layer adhere to the surface of the steel parts in the molten zinc of the steel parts after rust removal, so as to achieve the purpose of anti-corrosion. Anti-corrosion and anti-scratch, thick zinc layer, long anti-oxidation time, good anti-corrosion and anti-rust effect.
Plastic spraying: is a surface treatment method of spraying plastic powder on the parts. The plastic powder is charged by an electrostatic generator, adsorbed on the surface of the iron plate, and then baked, the powder is melted and adhered to the metal surface.The advantages are no need for thinner materials, no pollution to the environment and no toxicity to the human body during construction; excellent appearance quality of the coating, strong adhesion and mechanical strength; short curing time for spraying construction; much higher corrosion resistance and abrasion resistance of the coating; no bottom Paint; simple construction, low technical requirements for workers; lower cost than spray painting process.
