Jiangsu Huatal closed cooling tower adopt magnesium-aluminum-zinc plating sheets as outer shell

1. The development of magnesium-aluminum-zinc plating

In order to prevent the steel from rusting, the surface of the steel needs to be made up, and thus the coating material for zinc coating is derived. At the beginning, the material is made into the product and immersed into the hot zinc solution. But the result is a series of problems such as ugly surface and serious pollution. So the pre-plating material become more and more popular, and steel plant began to produce galvanized sheets. Galvanized sheet has been experienced a very long period of development in the Chinese market. Until now, most of the galvanized coil manufacturers use the outdated production process, produce rough products, surface quality is not up to standard, zinc layer is easy to fall off, a variety of problems, emerging in an endless stream. And most manufacturers fall into a price war, the lower the price, the worse the quality; The lower the quality, the lower the price. So many customers require to buy galvanized sheet which imported from Korea, such as eastern united, Nippon steel, posco and so on. After the manufacturers added aluminum into the plating material, the product's anti-corrosion and anti-rust performance will gain a lot of enhancement, at this time produced coating material is aluminum zinc, aluminum zinc plating can now meet the needs of most products anti-corrosion requirements. However, in some particularly harsh environments, higher requirements are put forward for coating materials. Therefore, Japan, which is surrounded by the corrosion of bad seawater, took the lead in the development of this material, magnesium-aluminum-zinc plating, which is composed of dense alloy coating. It is the most precise coating material on the earth, not one of them, but the best coating material.

2. Advantages of magnesium-aluminum-zinc plating

(1). Performance advantage: other such as galvanized, aluminum-zinc plating, its anti-corrosion and rust performance can not be compared with magnesium-aluminum-zinc plating. Compared with galvanized plate, the same coating, magnesium-aluminum-zinc plating's service life is 10-20 times than others.

(2). Specification advantage: galvanized sheet production of the maximum specification is 2.0mm (thickness). The maximum specification of aluminum-zinc plating production is 2.5mm. But the maximum specification of magnesium-aluminum-zinc plating can be produced up to 9.0mm (thickness), 0.27-9mm is the range of its production. 

(3). Incisional protection: incisional protection is also called self-healing, which is a special skill only for magnesium-aluminum-zinc plating. Sometime, during your production, you need to cut it to a certain size. After you cut it with a plate cutter, there is no coating protection at the edge of the cut. What will happen? Will rust! But magnesium-aluminum-zinc plating has its own notch protection function to ensure that this does not happen, and its surface coating has a fluidity that will gradually cover the exposed base metal over time, without any additional treatment. 

Jiangsu Huatal cooling technology co., Ltd has been in the forefront of change from galvanized board, aluminum zinc plate all the way. Since 2012, we have taken the lead in introducing magnesium-aluminum-zinc plate as agreed by the decision-making level of the company and at the strong request of customers, Mainly purchased from POSCO and Nippon steel, the corrosion of the outer shell of closed cooling tower was solved by extreme weather in coastal areas of China and northern China. Up to now, nearly 1000 sets of closed cooling towers have been produced, which are favored by the majority of customers, and we will keep providing the best products to our customers. Thanks for watching.
