What is the routine maintenance of steel grating?

At present, steel grid plate has a very good application in metallurgy, energy and other fields, as well as bridge and highway guardrail and other fields. What is the routine maintenance method of steel grating, which seems to be common but very important? What about the service life? Let's answer these two questions.

First of all, we need to know that because the steel grating needs to be used for a long time, its daily maintenance is very important, which requires us to develop the habit of regular cleaning and regular inspection. When maintenance is obtained, service life can be extended. The specific maintenance methods are as follows:

Under normal circumstances, the steel grille must be kept clean and free from all kinds of dirt, especially some corrosive residues, which should never be left on the grille. The steel grillage fixed by bolts should be checked frequently to see whether the bolts are loose and whether there are hidden dangers. If there is a case, it should be dealt with in time. When it is found that there is no zinc coating on the surface of the steel grating, it shall be treated with anti rust paint in time.

This can prolong the service life of the steel grating, but how long?

If it is steel grating, if it is used in a dry environment, it can be used for 70 or 80 years, no problem at all. If it is used in harsh environment, the service life will be 20 to 30 years, so the service life will vary with the environment. Therefore, when used in different areas, the service life is different. For example, in coastal areas, it is generally about 20 years. If the steel grating surface is not worn, the time can be a little longer.

However, in some arid and rainy places in the mainland, the air humidity is very low and the corrosive medium is very few, so the service life of the steel grating will be longer than that in coastal areas. Of course, it's also related to the applicable industry. For example, in the chemical industry, the corrosion is very strong, and the service life of steel grating will be shortened. In addition, there are differences between indoor and outdoor use.
