Hot-dip galvanized steel grating has many uses in our lives. We should know that galvanized steel grating has a very good anti-rust effect, so the service life of galvanized steel grating will be greatly extended. In addition to these reasons In addition, why are galvanized gratings so popular? Let's take a look below.
1. Anti-corrosion issues
Cold galvanizing is just coating zinc on the surface of the iron grating, which can be attributed to physical treatment, but this zinc layer is also easy to fall off. Hot-dip galvanizing is attributed to a chemical reaction, that is, chemical treatment. This zinc attachment on the surface of the steel grating It has stronger strength, is not easy to fall off, has good anti-corrosion effect, and has a relatively long cycle time, so the manufacturer uses hot-dip galvanizing.
2. Environmental issues
Burning zinc will definitely produce a lot of pollutants. The pollutants released by hot-dip galvanizing are generally the waste acid from pickling parts. However, the pollutants released by cold-dip galvanizing are not only the waste acid from pickling parts, but also the waste acid from pickling parts. There will be a lot of waste purification liquid, electroplating waste liquid, etc. Because cold galvanizing will release more pollutants than hot dip galvanizing, so hot dip galvanizing is used in most cases.
3. Differences in technology
Hot-dip galvanizing is to remove the oil on the workpiece, then pickle it, then soak it, and then dry it and put it into the molten zinc solution. The time must be increased; cold galvanizing, also called galvanizing, is Refers to the presence of zinc on the grating plate by removing oil, pickling, and then putting it into a zinc salt solution through an electrolysis device. Such a product has a hot-dip galvanized surface. Although there is no hot-dip galvanized finish, the galvanized layer It is many times thicker than hot-dip galvanizing, so the anti-corrosion performance is much better.
4. Self-weight is as light as snow
From the structural characteristics of the steel grating, it has ventilation characteristics, is not easy to accumulate stolen goods, saves the trouble of manual cleaning, and is also very convenient to install the steel grating. Connect with fixing clips, screws and welds. After installation is completed, it is recommended to use anti-rust paint for repair to avoid damage to the steel grating during the fixing process. The surface should be treated with rust.
5. Strong anti-corrosion effect and long service life
Another advantage of steel grating is that the surface will be hot-dip galvanized, which can avoid surface corrosion.
Why is hot-dip galvanized grating so popular? It is precisely because of the above advantages that hot-dip galvanizing has naturally become a very popular product.
