Galvanized Highway Guardrail

Product description

Hot-dip galvanized guardrail is the main form of semi-rigid guardrail. It is a continuous structure made of a patchwork of corrugated steel guardrail and supported by columns. 2. The hot-dip galvanized guardrail uses the deformation of the soil foundation, column and beam to absorb the collision energy, forcing the out-of-control vehicle to change direction and return to the normal direction of travel, preventing the vehicle from rushing out of the road, thereby protecting the vehicle and passengers and reducing the loss caused by the accident. The corrugated beam guardrail is soft and flexible, has a strong ability to absorb collision energy, has a good line-of-sight induction function, can coordinate with the road alignment, and has a beautiful appearance.

How to test the anti-corrosion coating quality of guardrail?

We can cut a small section of the guardrail as a sample to test, hit the surface of the sample with a hammer, observe whether the coating will fall off as a whole, see whether the coating and the galvanized material inside are completely bonded together, if these are not problems, it indicates that the manufacturer's process is good and trustworthy. You can also let the manufacturer provide the relevant quality inspection report to see whether the value is up to standard according to the industry regulations.

Zinc steel substrate is made of black strip steel made of various specifications of corrugated guardrail plate, after hot dip galvanized, the surface of the guardrail zinc content reached 300-600g/㎡, in the natural environment can be used for 5-10 years rust. Spray wave guardrail is the galvanized sheet again deep processing: after mechanical molding, chemical treatment, electrostatic spraying, high-temperature imitation enamel curing, that is to complete the spray treatment. The galvanized layer of the spray guardrail is 40 microns, the spray layer is 76 microns, and the total anti-corrosion thickness is not less than 116 microns, that is, it meets the national standard of spray plastic, and the normal outdoor environment can be used for 10-25 years.
