Steel grating is an open steel member that is made of bearing flat steel and crossbars that are orthogonally combined at a certain distance and fixed by welding or press locking; crossbars are generally made of twisted square steel, but also round steel. Or flat steel, the material is divided into carbon steel and stainless steel, which has the advantages of ventilation and light transmission, anti-skid, strong bearing capacity, beautiful and durable, easy to clean, easy to install, etc. It is widely used in power stations, shipbuilding, chemical engineering and other fields. What factors will affect the quality of steel grating during its use?
1. Tolerance:
The public service including the diagonal line of the flat steel is controlled within a very good scale. Does the public service of the flat steel conform to the national standards and national standards?
2. The quality of flat steel raw materials:
Flat steel is the most important part of steel grating and bears the largest load in the whole structure. In order to reduce production costs and make more money, some manufacturers will use flat steel made by secondary processing of scrap steel.
3. Proofreading and welding of flat steel:
After the flat steel is purchased, it may not be completely parallel. In addition, the flat steel may be slightly twisted due to hoisting during transportation. Don't underestimate this twist. If the steel grille is a little twisted, it will cause welding. The steel grille that comes out is deformed, so proofreading is very important.
Welding is a very important part, and the quality of welding will directly affect the bearing capacity of the steel grid and its life. If the welding is not good, the welding may be started directly after a few days, and such a steel grille cannot be used.
4. Hot-dip galvanizing of steel grille:
Hot-dip galvanizing is very important to the steel grating, which is the appearance of the steel grating. The first criterion for customers to judge the steel grating is the appearance of hot-dip galvanizing. Hot-dip galvanizing is not only beautiful, but also its anti-rust ability. If the quality of hot-dip galvanizing is good, the natural life will be long.
5. Packing and delivery:
The final point is that the steel grille is packaged and shipped. When loading, don’t use a forklift to place the steel grille at will because it is solid and not easily damaged. When loading the steel grille, you should also handle it with care. You can't pick everything at will, especially the relatively thin steel grille, which simply leads to the deformation of the steel grille.
