1. Keep it clean at ordinary times, and don't be covered with all kinds of dirt, especially some corrosive residues.
2. If it is found that the galvanized layer is gone, it should be coated with anti-rust paint in time.
3. Choose to buy galvanized steel grating A brief introduction to hot-dip galvanized steel grating: Hot-dip galvanized steel grating must be derusted first. The first step is immersion in an acid bath to remove rust. The second step is to immerse in the tank. At this time, the acid stains are removed, and the electroplating additives are soaked, commonly known as liquid medicine. This liquid medicine is proportionally adjusted by chemicals. It is then dried and dipped in a zinc liquid. Zinc liquid is about 420°. After the iron steel grating is immersed in the zinc liquid, the first step is a chemical reaction to form a zinc-iron alloy, and then in the zinc layer, the zinc content on the hot-dip galvanized steel grating is 610g/m2, 85 microns/m2, and then immersed in water to cool , and then immersed in the passivation solution to add the last layer of protective film. Therefore, the service life of hot-dip galvanized steel grating will be longer. Rust spots are not easy to produce.
