What's the quality of Daria radiator?

Daria radiator has a nice name. I don't know whether it is imported or not, and what is the quality. It can be said that the brand has a great influence on the price of radiators in Beijing. There are many brands of radiator in Beijing, both imported and domestic. Generally, imported brands are more expensive than domestic brands. As a domestic brand, the quality of radiator will be different due to different brand influences. In addition, the domestic central heating water quality is poor, and it is easy to produce scale. In order to improve the hardness of water, sodium chloride needs to be added to the boiler, so the corrosion resistance and heat dissipation rate of the radiator are required to be higher. In terms of corrosion protection, its wear resistance can be seen. The inner wall of radiator has been washed by some impurity particles in heating water for a long time, so the inner anti-corrosion coating must have excellent wear resistance, otherwise it will be easily scratched or thinned due to wear, which will reduce the service life. For more than ten years, Golden Flagship has always put the interests of users first, and adopted the latest anti-corrosion coatings developed by Wuhan University, which can be used for reference by the anti-corrosion industry.
