Road guardrail

Galvanized steel pipe guardrail: not easy to deform, with a long service life. Its anti-oxidation and corrosion resistance are excellent, and it can effectively resist the erosion of the external environment. During the production process, the galvanized steel pipe is specially treated to form a galvanized layer on the surface. This galvanized layer can prevent oxygen and moisture from reacting with the metal inside the steel pipe, thereby protecting the steel pipe.

Iron pipe guardrail: It is light in weight and cheap in price, which makes it have certain advantages in some projects with strict cost control. However, the quality of iron pipe guardrail is slightly inferior to that of stainless steel and galvanized pipes. It is easy to rust and has relatively low strength. It may be deformed or even damaged when subjected to large external force impact.
