[[MetaDescription]]
Hot dip galvanized steel bar grating is also called hot dip galvanized grating or hot dip galvanized steel grating. It is made of loaded flat steel and crossbars arranged at a certain distance between the latitudes and longitudes. It is welded on a high-voltage resistance welding machine to form an original plate. The product is processed by hole opening, edging, and other processes. It has the characteristics of high strength, light structure, beautiful appearance, high load-bearing capacity, and easy hoisting. Widely used in petrochemical, power plants, water plants, sewage treatment plants, municipal engineering, sanitation engineering and other fields of platforms, walkways, trestles, trench covers, manhole covers, ladders, etc.

Types And Usage
* Plain-type hot dip galvanized grating is mainly used for platforms, walkways, various trench covers, step boards, etc.
* Serrated shape hot dip galvanized grating has a good anti-skid effect. Widely used in the petrochemical industry, power plants, waterworks, sewage treatment plants, municipal works, and sanitation projects in areas.
* Compound-type hot dip galvanized grating: It can prevent small parts from falling. Use double mesh panels in granaries, restaurants, warehouses, etc., to prevent small animals such as mice from entering.
Use Conditions
* The service life of it depends on the place of use, generally about 20 years in coastal areas. If there is no major wear on the surface, the time can be longer;
* In inland areas, it is believed that there is no problem with drought and less rain, low air humidity, and less corrosive media, and the life of hot-dip galvanized steel grating can reach more than 30 years;
* There are also differences between indoor and outdoor use. In the environment range of PH6～PH12.5, a stable protective film is formed on the surface of the galvanized layer, which is very good in different environments.
