Introduction to the rust prevention principle of zinc steel guardrail

Introduction to the rust prevention principle of zinc steel guardrail

One: The zinc steel guardrail base material is a zinc steel alloy produced by an advanced high-temperature hot-dip galvanizing process with strong corrosion resistance.

1. Unique multiple anti-rust protection of hot-dip galvanizing;

2. Excellent hardness: the hardness value of zinc alloy reaches 211DPN, which is 1/3 stronger than the hardness value of ordinary steel 159DPN;

Two: the surface of zinc steel guardrail; it adopts the color polymer imitation enamel electrophoresis high temperature curing process, which has stronger anti-corrosion ability than ordinary spraying. It can withstand 50 kilograms of impact per square centimeter, and has better UV resistance and better oxidation resistance. , Resistance to salt and alkali, weather resistance, fog resistance, etc., and its surface gloss, color and self-cleaning performance have exceeded the national first-level standard for protective fences, ensuring that the surface color change does not exceed 5% in 15 years.

Three: Processing characteristics of zinc steel guardrail products

1. The popular combination interleaving process is adopted, and any connection is made of high-strength modified engineering nylon connectors, without welding, to ensure that the base material is not damaged, and to enhance the rust resistance;

2. Higher-strength modified engineering nylon connectors have better anti-ultraviolet, more anti-oxidation, more salt-alkali, weather resistance, fog resistance, etc., and can withstand about 1.83 tons of impact per square centimeter, and have a service life Longer;
