The strength of the steel grating is very good, and it is now used in airports, railway stations, docks and various categories. Because the strength of the steel grating is very good, its load-bearing capacity cannot be compared with many data. For example, the tread plate of the steel grating can accept very heavy weight, so many people have found it strange why the strength of the same steel grating is different. Since the strength performance of the steel grating is the original data for the manufacture of the steel grating, the original data is very important for any product. If the steel grating purchased by the customer is produced by a large manufacturer, the strength must be very good, because the large manufacturer is very strict in manufacturing the steel grating. A good steel grating can be used in many fields. For example, many people have found that there are steel gratings on some steps of high-rise buildings. Only these steel gratings have changed shape, which makes it difficult for many people to recognize them. Now many people apply steel grating to their own house construction. Many customers said that they jumped twice on the steps made of steel grating, and there was no deformation. This is enough to prove that the strength of the steel grating is very good, but it is still recommended not to use such risky actions to check the strength of the steel grating. The appearance of galvanized products is not only beautiful, but also delicate. The difference between galvanized steel grating and non-galvanized steel grating lies in its surface treatment. Galvanizing is divided into hot galvanizing and cold galvanizing. Galvanized steel grating can prevent oxidation and prolong its service life. Hot-dip galvanized steel grating has strong corrosion resistance between PH6-PH12, and its service life has a great relationship with the external environment. In a dry environment, its service life can reach 70-80 years, and it is generally 20-30 years in industry. The service life of cold galvanizing is relatively short, and rust will begin to appear in 2 or 3 years. If it is not galvanized, it will not only have a rough appearance, but also the product can be painted and the surface will not be treated. The service life of hot-dip galvanized step board is as long as 40-70 years. The length of the cold galvanized trench cover is 3 years, and the painted steel grating is 5-7 years. The surface of non-galvanized products is easy to blacken and rust, while the surface of galvanized products is very shiny, with a relatively long service life and beautiful and durable appearance.
