With the emergence of steel structure products, steel gratings have become a ubiquitous product in our daily lives. Anping manufacturers have a variety of steel grating products. The company often receives many inquiries from consumers. I don’t know. How to identify high-quality galvanized steel gratings, such as how much money can truly identify which steel gratings are good and which ones are of poor quality. The quality of steel gratings at the same price range actually varies greatly, so to avoid buying bad steel gratings, the sales staff of the manufacturer will give you a brief introduction on how to identify them when purchasing.
Raw materials: The quality of steel is an important factor, because in order to reduce costs, many manufacturers will use steel produced by many small steel manufacturers, thereby greatly reducing the quality of steel gratings, so when selecting steel, it must be It will take a big steel producer.
The thickness of steel grating has great applications in our daily life. For example, some stairs have steel grating, so the thickness of steel grating is very important at this time, because it is related to people's life safety. .
Steel grating generally requires surface treatment to prevent corrosion. Hot-dip galvanized steel grating and cold-dip galvanizing are widely used. Steel grating is widely used in alloys, building materials, power stations, and boilers. In shipbuilding, petrochemical, chemical and general industrial plants, municipal construction and other industries, as a protective product, it is very important to carry out galvanizing anti-corrosion treatment.
The corrosion of steel grating is a chemical reaction. If the metal is exposed to the air for a long time, a galvanic cell will be formed due to the difference in the reducibility of the carbon and other impurities in it. The iron will be oxidized into iron oxide and lost. Because of the reduction of zinc It is stronger than iron, so the galvanic reaction formed outdoors after the steel grating is galvanized consumes zinc instead of iron, thereby protecting the iron.
In addition, zinc easily forms a dense oxide film, which prevents oxidation from continuing. Zinc is also easier to apply paint to prevent contact with oxygen in the air.
