Hot dip galvanized bridge guardrail
FORST hot-dip galvanized bridge guardrail has the following advantages:
Galvanized layer protection: During the hot-dip galvanizing process, iron or steel is immersed in the galvanizing solution to form a strong galvanized layer, which can effectively prevent the corrosion of iron or steel and prolong the service life.
Strong Durability: The galvanized layer provides additional protection, making the guardrail highly durable and corrosion-resistant, capable of long-term use in harsh climate conditions.
Low maintenance cost: The hot-dip galvanized guardrail requires almost no maintenance and does not require frequent paint repairs, which saves maintenance and maintenance costs.
Beautiful: The hot-dip galvanized guardrail has a bright silver-white appearance, which is in harmony with the surrounding environment, giving people a neat and beautiful feeling.
Easy installation: The hot-dip galvanized guardrail adopts a modular design, which can be assembled and disassembled according to needs, and the installation process is simple and fast.
