Toothed steel grating is very common in people’s production and life. During use, since the toothed steel grating is directly exposed to the air, it is easily affected by acid-base corrosion and other factors. Therefore, when people use the toothed steel grating, they will treat it on the surface. The main purpose is to protect the toothed steel grating from external influences, so that the toothed steel grating is beautiful and practical, and plays a better role. This is more important.
In the use of toothed steel grating, there are many treatment methods on the market, and the popular ones are hot-dip galvanizing and cold-dip galvanizing. Because the chemical properties of zinc are very stable, when heat treatment or electrical treatment is used, it can be directly wrapped in the flat steel of the steel grating, which has a good protection effect on the inner steel plate. After this treatment, the toothed steel grating looks obviously more visually superior. When used in municipal buildings, the toothed steel grating has a good aesthetic appearance. Of course, this treatment is very popular, and the service life of the whole toothed steel grating is significantly increased. This is in the surface treatment of these materials. After that, a good impact can be produced.
When welding the toothed steel grating, straighten the flat steel before welding. If the flat steel is in an arc- haped bending state, the flat steel is not straightened before welding, but the flat steel is directly welded on the die, which looks straight on the surface. In fact, at this time, the teeth The steel grating already has strong internal stress. Before pickling and hot-dip galvanizing, the internal stress is removed from the toothed steel grating. If the internal stress is manifested, the shape will become a horizontal bow. .
The toothed steel grating has brought a lot of convenience to people, so it is more and more widely accepted by people.
