Effectively Extend The Service Life Of Galvanized Steel Grating

Nov. 30, 2020

China is a major steel country in the world, and its annual output is one of the largest steel countries in the world. In many steel structure projects, galvanized steel gratings are used. With the wide application of steel frames in the construction industry, the use of galvanized steel grating has been developed, whether it is industrial construction or municipal engineering, the application plan of galvanized steel grating has been widely used.

As an important building material product, the domestic demand for galvanized steel grating is increasing. When customers buy steel gratings, they also want to buy durable steel grating products. The longer the service life of the galvanized steel grating , The customer’s cost is lower. Therefore, how to extend the service life of the galvanized steel grating has become an important issue.

1.In order to effectively extend the service life of the steel grating, the following aspects need to be paid attention to

When selecting materials, the raw materials of the galvanized steel grating should be selected strictly in accordance with the design load. 4mm thick flat steel cannot be replaced by 3.5mm thick flat steel. If the lower difference plate is used excessively to make the steel grating, under long-term overload conditions , Only the stagnant steel grille will deform, bend or even break.

When welding, the hemp steel and flat steel of the galvanized steel grating must be completely welded during welding, and there must be no gaps. If large-scale floating welding occurs, the life of such galvanized steel gratings will not be very long.

In galvanizing, corrosion must be prevented, and the pickling should be thorough before pickling. And there should be no residual iron oxide, otherwise, the zinc layer cannot adhere to the surface of the steel grid during galvanizing. When galvanizing, to ensure sufficient temperature and heat, the zinc layer should not be too thin (affecting the corrosion age) and not too thick (when it is too thick, the surface zinc layer will fall off). The later maintenance of the galvanized steel grating is also very important, and the strong corrosive substances left on the surface of the steel grating should be cleaned regularly.

2. Why is the galvanized steel grating so popular?

The reason is that the galvanized steel grating components are small in size, light in weight, easy to transport and equipment, easy to assemble, disassemble and expand, and the galvanized steel grating is corrosion-resistant, and the surface of the galvanized layer Very strong, can protect the steel grid from oxidation, and then applied to the large-span, high-strength, heavy-load steel structure.

The galvanized steel grating has uniform material, stable quality, high reliability, good corrosion resistance, good fire resistance, high strength, good plasticity, vibration resistance, strong impact resistance, strong wind resistance, and can withstand 70 meters per second Hurricane can withstand and protect life and industrial safety. High degree of industrialization, high processing precision of factory manufacturing and on-site equipment, short manufacturing cycle, high production efficiency, fast construction speed, production cost savings, economic and environmental protection, galvanized steel gratings are all metal materials, and the recyclability rate is as high as 100% , residual value may include low cost.
