If u want to buy galvanised rainwater tanks, should pay attention to sth. like what?
Customers who purchase a galvanised rainwater tanks will know about the galvanized water tank. For example, the performance of galvanized steel tank and so on. These problems are we have to buy when the manufacturers of galvanized water tank must be introduced to you. But some manufacturers introduced is not very detailed, it is only some basic things and our customers a brief introduction, but some of the internal requirements of galvanized water tank, the inherent quality problems are not necessarily say to you.
The election to buy water tanks on the water tank, it must be the best choice. The following to explain to you on the customers do not understand the galvanized rainwater tank of some professional knowledge. Such as hot galvanized and cold galvanized difference?
Some production of galvanized rainwater tank is divided into hot-dip galvanized, there are divided into cold galvanized, the following look at the difference between them
1, hot-dip galvanized, also known as hot-dip galvanized, it is at high temperature to melt the zinc ingot, put in some auxiliary materials, and then the metal structure into the galvanized tank, the metal components attached to a layer of zinc . The advantages of hot-dip galvanizing is its ability to resist corrosion, galvanized layer adhesion and hardness better. Cold plating “or” electroplating “that is, the zinc salt solution through electrolysis, to plating on the coating, in general, without heating, the amount of zinc is very small, easy to fall off in wet environments.
2, hot-dip galvanized, for steel grating, manufacturers strongly recommend hot-dip galvanizing hot-dip galvanizing is a chemical treatment, are electrochemical reactions. Cold galvanizing is a physical treatment, but a layer of zinc in the surface brush, so easy to fall off the zinc layer. The use of hot-dip galvanizing in construction. Continuous hot-dip galvanizing process, steel → heating → cooling to the galvanized temperature → galvanized → cooling Cold galvanizing is electro-galvanized, only 10 ⊕ 50g / m2, its own corrosion resistance than hot-dip galvanized a lot worse. The use of electro-galvanized the price is relatively cheap.
