The cost of spraying is lower than that of galvanizing.

After the iron plate is made in the hot-dip galvanized 30% more expensive, the hot-dip galvanized sheet is directly made and sprayed plastic, depending on your use of the occasion, you need to contact me.

What are the specific specifications? Shanghai Baojute Industry specializes in the production and sales of bridges, and hot-dip galvanized bridges are more expensive than sprayed bridges.

Generally speaking, ** are almost the same, depending on what occasion you use it, the specific selection requirements.

Features of spray tray tray.

The main features are: enhanced corrosion resistance, aging resistance, increased adhesion, and you can also choose the color you like to match the architectural design as the appearance style of the bridge.

The process uses the corona discharge phenomenon to make the powder adsorbed on the cable tray, the powder melts into the spray gun with the help of compressed air gas, the spray gun head has the high voltage generated by the high-voltage electrostatic generator, and produces a dense charge pool near it, when the powder is sprayed out by the nozzle one after another, the charged paint particles are formed, and the action of electrostatic force is absorbed into the bridge shell, as the powder sprayed out by the spray gun is more and more, the charge accumulates more, and the electrostatic repulsion effect will not continue to be adsorbed when it reaches a certain thickness. The bridge obtains a powder layer of a certain thickness, and then the powder is fused at a high temperature of 200°C baking paint, and a hard and beautiful coating film is formed on the surface of the bridge.

Bridge spraying does not need thinner, construction to the environment no pollution, no toxicity to the human body, excellent coating appearance quality, strong adhesion and mechanical strength, spraying construction curing time is short, coating corrosion resistance and wear resistance is much higher, no primer is required, construction is simple, low technical requirements for workers, the cost is lower than the painting process, some construction occasions have clearly proposed that the electrostatic spraying process must be used, and the electrostatic powder spraying process will not appear in the process of spraying paint common flow phenomenon. The effect of cable tray spraying improves the corrosion resistance and aging resistance of the cable tray. It can play a good role in protecting the metal of the bridge body.
