Some basic knowledge of zinc steel guardrails

The substrate of the zinc steel guardrail profile is a high-temperature hot-dip galvanizing material. The hot-dip galvanizing refers to putting high-quality steel into a zinc bath of several thousand degrees. After soaking for a certain period of time, the zinc liquid will penetrate into the steel to form a A special type of zinc steel alloy, the surface of hot dip galvanized material can be etched for 30 years without any treatment in the field environment.

Zinc steel guardrails On the rust prevention problem, the fence substrate is made of hot-dip galvanized square tube, which prevents the substrate from rusting from the source, then is washed, phosphatized, and finally electrostatically sprayed. Electrostatic spraying is to spray plastic powder on the surface of the guardrail. Compared with the paint, the color is more beautiful, the adhesion is stronger, and it does not need to be maintained every year. It is equivalent to packaging a layer of plastic on the surface of the fence, which makes the hand feel smoother and more delicate.

Therefore, the zinc steel guardrail is also called the electrostatic spray guardrail. At the same time, the pickling before spraying, the phosphating greatly improves the adhesion of the powder, and the life of the zinc steel guardrail is up to 30 years. This is why the zinc steel guardrail is used. The main reason for such a long life.
