The overall price of domestic building steel products continues to rise, in which the rise of the spiral steel and wire rod in Beijing and Tianjin is more than 200 yuan/ton; Last week, the downward trend of the board ended, and the board rose again in all directions, reaching three cities with an increase of more than 100 yuan/ton. The cold rolling has gone up a lot, and the hot rolling has been greatly increased when the factory price has been greatly increased, such as Baosteel and Angangsteel. Large and medium – sized material small increase. Analysts expect construction China steel gi pipe prices to rise in general next week.
There’s a lot of hot zinc, more often used to be steel pipes or solar steel, which is going to be hot galvanized, and the performance of the product will be greatly improved, and a lot of people don’t really know about the benefits of hot galvanized, and in fact, many of the products are made with hot zinc.
First of all, the biggest role of hot dip galvanization is to prevent the body from rusting. We all know that no matter what product rusts, it will reduce its life. The rusting corrodes the material itself very quickly. Galvanized, it makes the product more beautiful, not the color of the product that’s not galvanized, it’s not nice, and zinc is silver, so the galvanized product looks cleaner and beautiful.
The unique advantage of China hot dipped galvanized steel pipe is its environmental protection, no pollution, low cost, saving time and energy, and giving people more time, energy and money.
China galvanized steel pipe is a single layer of zinc coated on a narrow and long steel sheet by means of cold rolling or hot-rolling, which is zinc-plated and galvanized, which is more uniform, strong in adhesion, long service life, and which can make galvanized steel pipes corrosion-resistant, and which can be corrosion-resistant, and rust or phenomenon can occur during use, so what is the cause?
The corrosion of the gi square steel pipe is the main reason for the coating surface. The chemical properties of zinc are more active, which can be soluble in both acid and alkali. In humid environment, zinc will react on the surface, forming alkaline zinc carbonate film, and contacting materials with hydrogen sulfide. The zinc resistance will be less corroded, which is easy to corrode, exposing the surface of steel plate and eventually rusting. The corrosion probability of galvanized steel plate is relatively low, because the galvanized layer is thicker, it is not easy to cause the steel plate oxidation, so it is not easy to rust.
Galvanized steel pipes are becoming increasingly popular in some large factories because of the high corrosion resistance of galvanized steel pipes, which we want to describe in more detail in order to save galvanised life.
The corrosion resistance of hot dipped galvanized square steel tube has entered into people’s concept, so the anti-corrosion treatment of galvanized steel pipe is not paid much attention to by people, and the anti-corrosion ability of galvanized steel pipe can be easily enhanced, which is largely ignored.
Galvanized steel pipes are used on the ground, sometimes with mud. The traditional concept is that galvanized steel pipes will no longer work in this case. This concept is actually an oversight of the use of galvanized steel pipes. Because zinc itself can oxidize, but it’s slower than iron. However, if galvanized steel pipe is treated with corrosion, it can be more beneficial to the life of galvanized steel pipe. The antiseptic treatment for underground use is to coat the steel exterior with epoxy coal tar asphalt, adhesive tape and other coatings.
In fact, these seemingly simple methods can be applied to the protection of galvanized steel pipes commonly used, and can be handled before they are put into use, so as to reduce the tedious construction trouble in the construction process.
