Corrugated guardrail hot dip galvanizing is also called hot dip zinc and hot dip galvanizing: it is an effective metal corrosion prevention method, mainly used in metal structure facilities in various industries. It is to immerse the steel parts after rust removal into the melting zinc liquid about 500 ° C, so that the surface of the steel member is attached to the zinc layer, so as to play the purpose of anti-corrosion. Hot-dip galvanizing process: finished product pickling - washing - adding plating solution - drying - hanging plating - cooling - medicine - cleaning - polishing - hot-dip galvanizing completed. Hot galvanizing is developed from the older hot plating method, and has a history of one hundred and forty years since the application of hot galvanizing to industry in France in 1836. However, the hot dip galvanizing industry has been developed on a large scale in the past 30 years with the rapid development of cold rolled strip steel. More than 90% of the highway corrugated beam steel guardrail is treated by hot dip galvanizing process, which has the advantages of anti-corrosion and anti-scratch, thick zinc layer, long anti-oxidation time and good anti-corrosion and anti-rust effect.

Wave guardrail spray is a surface treatment method that sprays plastic powder on parts. Spraying is also we often talk about electrostatic powder spraying, it is the use of electrostatic generator to make plastic powder charged, adsorbed on the surface of the iron plate, and then after 180 ~ 220℃ baking, so that the powder melt and adhere to the metal surface, spraying products are mostly used for indoor use of the box, paint film showing flat or matte effect. Spray plastic powder mainly acrylic powder, polyester powder and so on. The advantage is that there is no need for thin material, the construction is pollution-free to the environment and non-toxic to the human body; The coating has excellent appearance quality, strong adhesion and mechanical strength; Spray curing time is short; The corrosion and wear resistance of the coating is much higher; No primer required; Simple construction, low technical requirements for workers; The cost is lower than the spray painting process; Some construction occasions have clearly proposed that electrostatic spraying process must be used; In the process of electrostatic powder spraying, the common flow phenomenon in the spray painting process will not appear. Waveform guardrail adopts this technology to treat the surface, in general, there are three ways:

1. The steel plate is sprayed directly.

2. Cold galvanized steel spray.
3. It uses the deformation of the soil foundation, column and beam to absorb the collision energy, and forces the out-of-control vehicle to change direction, return to the normal direction of travel, and prevent the vehicle from rushing out to protect the vehicle and passengers and reduce the loss caused by the accident.

Categories:
According to the waveform can be divided into double wave guardrail and three wave guardrail.
According to the surface treatment is divided into hot-dip galvanized corrugated guardrail and galvanized spray plastic two.
According to the location, it can be divided into roadside guardrail and central divider guardrail.
The highway waveform guardrail plate can be divided into A and S levels according to the anti-collision grade. S-class guardrail is A reinforced type, suitable for use in particularly dangerous sections on the side of the road, and A-class is used for special highways. Common roadside waveform beam guardrail can be divided into B, A, SB, SA, SS five levels according to the anti-collision grade.

System principle:
1, highway guardrail is the main form of semi-steel guardrail, it is a corrugated steel guardrail plate splicing each other and supported by the column of the continuous structure.
2. Highway guardrail uses the deformation of soil foundation, column and beam to absorb collision energy, and forces the out-of-control vehicle to change direction, return to the normal direction of travel, and prevent the vehicle from rushing out to protect the vehicle and passengers, and reduce the loss caused by the accident.
3, waveform beam guardrail steel soft phase, has a strong ability to absorb collision energy, has a good line of sight induction function, can be coordinated with the road alignment, beautiful appearance, can be used on small radius curves, damage is easy to replace
