The difference between galvanized flat steel and galvanized round steel

- Dec 16, 2020-

The application of galvanized flat steel has also expanded correspondingly with the development of industry and agriculture. Therefore, the enterprises engaged in the production of galvanized flat steel in China are also required to have higher requirements for the galvanized flat steel. It is also because of the high new reference price of galvanized flat steel, so the production and process requirements are also very high, so the application range and type of flat steel is also very rich. So what is the difference between galvanized flat steel and round steel?

1. Different shape By name, it can be known that galvanized round steel refers to a solid strip of steel with a circular cross section, so the round steel is different from other steel profiles; but the galvanized flat steel has a rectangular cross section and is slightly pure The side can be made into other galvanized steel, which has the characteristics of high strength and light structure, and is opposite to round steel. Therefore, galvanized flat steel can be used as a material for making hoop iron, tools and mechanical parts, and used as a frame structure in construction. Pieces, escalators;

2. The application range of round steel has broad application prospects and is widely used in hardware, construction, and manufacturing industries. A small amount of round steel will also be used for building renovation. At the same time, round steel is also suitable for the processing of ordinary mechanical parts, such as rod steel parts, or bolts and nuts; and galvanized flat steel adopts negative deviation rolling, which can be designed by the actual construction needs of the thickness and width of flat steel. The galvanized flat steel is the same as the actual use after leaving the factory, so there is no need to cut the flat steel. Today, galvanized flat steel is used in the production and use of steel machinery manufacturing, automotive industry, cranes and other large machinery industries; therefore, the new market price of galvanized flat steel is also more expensive than round steel. In recent years, due to galvanized flat Steel has been used in large quantities, and the number of companies producing galvanized flat steel is also increasing. With the increasing demand for steel anti-corrosion in recent years, many steels have been replaced with galvanized flat steel, because galvanized flat steel can adhere to the surface through the zinc layer, which is anti-corrosive and suitable for humid environments. At the same time, the galvanized flat steel with anti-corrosion has not only an aesthetic appearance but also a superior hardness.
