The appearance of hot-dip galvanized steel grating is treated with special hot-dip galvanizing. Its chemical and physical properties are stable and it is not easily corroded and oxidized by air and microorganisms. It can significantly enhance the trench load capacity and prevent collapse. The hot-dip galvanized steel grating with a flat steel distance of 3 cm has a greater impact resistance and has the characteristics of a large span. Its service life is very long, generally in the range of 40 to 50 years. If there is no human damage factor involved, Hot-dip galvanized steel grating is a very good steel frame structure and load-bearing platform.
Why is it recommended to buy hot-dip galvanized steel grating?
Hot-dip galvanized steel grating is better than others in terms of function and cost-effectiveness, and it is the main choice for corporate customers to purchase.
It is difficult for customers to tell the difference between hot-dip galvanized steel grating and cold-dip galvanized steel grating from the appearance color. Since cold-dip galvanizing is a zinc salt solution that is electrolyzed and coated on the steel grating, it does not need to be carried out. After heating, the surface zinc content is very small, and the zinc content of electro-galvanizing is only about 10 grams. As a result, the cold-galvanized material will easily fall off when encountering some humid environments. The anti-corrosion function of hot-dip galvanized steel grating is good through hot-dip galvanizing treatment. Hot-dip galvanizing not only adds zinc elements but also adds some auxiliary elements to make steel gratings have such a good anti-corrosion effect.
The price difference between galvanized steel grating and non-galvanized steel grating mainly depends on what kind of galvanizing treatment the steel grating has undergone. There are two methods of galvanizing steel grating: cold galvanizing and hot dip galvanizing.
For regular steel grating manufacturers, the price of hot-dip galvanized surface-treated steel grating is about 1,400 yuan to 1,800 yuan per ton. The prices of steel gratings with different thicknesses are different. The market price of cold-dip galvanized surface treated steel grating is between 700 yuan and 900 yuan.
So what external factors will accelerate the damage of hot-dip galvanized steel grating?
The editor will give us a brief introduction: due to load changes, long-term use will lead to certain changes in the specifications of hot-dip galvanized steel gratings, resulting in a lack of structural bearing capacity. Due to various influences, hot-dip galvanized steel gratings will Deformation, twisting, denting and other phenomena will lead to weakening of component sections, warping of rods, cracking of connections, etc. Under the action of temperature differences, cracking and warping of hot-dip galvanized steel grating components or connections will occur, and corrosion will occur due to the corrosion of chemical substances. As well as electrochemical corrosion, the cross-section of hot-dip galvanized grating components will be weakened, so it is recommended to choose those with surface treatment. Others include the layout and production process of hot-dip galvanized steel grating, as well as errors in installation, illegal use and operation, etc. The above factors will affect the quality of hot-dip galvanized steel grating. The editor recommends that when using hot-dip galvanized steel grating, When grating, adhere to regular maintenance to extend the service life of the product.
