Fuzhou Xiamen Quanzhou Putian direct supply of corrugated guardrails, on-site construction and installation of anti-collision guardrail panels

>Corrugated guardrails are highway anti-collision facilities. They are mainly made of galvanized steel plates to prevent out-of-control vehicles from running off the road. Guardrails of different specifications are used for different grades of highways. The length of the corrugated guardrail board is meters. When installed, each side takes up centimeters and a net remaining meter of meters. The plate width is in centimeters and the corrugation depth is in millimeters. The plate thickness is divided into millimeters.
>The specifications and diameters of corrugated guardrail columns are divided into millimeters and millimeters, which are suitable for rural roads, county-level roads, mountainous roads and provincial roads. Suitable for highways. The thickness of corrugated guardrail columns is divided into millimeters and millimeters. The height of the column is generally left centimeter - centimeter above the ground. The specific column height is determined by the customer and produced in the workshop to length.

Guardrail surface treatment methods
> Cold galvanizing is also called electro-galvanized road anti-collision corrugated guardrail picture. It uses electrolysis equipment to pass pipe fittings through Remove oil, pickle, and then put it into a solution composed of zinc salts and connect it to the negative electrode of the electrolysis equipment. Place a zinc plate on the opposite side of the pipe and connect it to the positive electrode of the electrolysis equipment. Turn on the power and use the directional movement of the current from the positive electrode to the negative electrode. A layer of zinc is deposited on the pipe fittings. Cold-plated pipe fittings are processed first and then galvanized.
Cold galvanizing coatings mainly perform anti-corrosion through electrochemical principles. Therefore, it is necessary to ensure full contact between the zinc powder and the steel to generate an electrode potential difference, so the surface treatment of the steel is very important. In theory, electro-galvanizing can reach or even exceed the zinc layer thickness of hot-dip galvanizing. However, in general, the electro-galvanizing layer is generally thinner, resulting in poorer anti-corrosion and anti-rust effects than hot-dip galvanizing. The protection life is shorter and the anti-scratch effect is poor, but the relative cost is The low-price corrugated guardrail has a brighter appearance than hot-dip galvanizing.

>Plastic spraying is a surface treatment method in which plastic powder is sprayed on parts. Plastic spraying is also what we often call electrostatic powder spraying. It uses an electrostatic generator to charge the plastic powder and adsorb it on the surface of the iron plate. Then it is baked at ~℃ to melt the powder and adhere to the metal surface. Plastic spraying products are mostly used in boxes for indoor use. The body paint film has a flat or matte finish. Plastic spray powder mainly includes acrylic powder, polyester powder, etc.
Advantages: No need for thinner construction, no pollution to the environment, no toxicity to the human body, excellent appearance quality of the coating, strong adhesion and strong mechanical strength, spray construction, short curing time, much higher corrosion resistance and wear resistance, no primer required, easy construction The technical requirements for workers and the low cost are lower than those of the spray painting process. Some construction sites have clearly stated that the electrostatic spray process must be used to deal with the electrostatic powder spraying process. The common flowing phenomenon in the spray painting process will not occur during the electrostatic powder spraying process.
Corrugated guardrails often use this technology to treat the surface. Generally, there are the following methods: Direct spraying of steel plates. .Steel plate is cold-dip galvanized and spray-coated. .Steel plate is hot-dip galvanized and spray-coated.
