Galvanization (Zinc) channel steel (Steel) can be divided into hot-dip galvanized channel steel and hot-dip galvanized channel steel according to the difference in galvanizing process (gōng y), which is rust cleaning (rust cleaning) ( After rusting, the steel parts are immersed in the molten zinc solution at about 440 ~ 460 ° C, so that the surface of the steel member (biǎo miàn) adheres to the zinc layer, thereby achieving the purpose of anticorrosion (Purpose). Shenzhen steel plate wholesale is a flat steel made by pouring molten steel and pressing it after cooling. Steel plates are divided according to thickness, thin steel plates <4 mm (0.2 mm thinnest), thick steel plates 4 to 60 mm, and extra thick steel plates 60 to 115 mm. Steel plates are divided into hot rolled and cold rolled according to rolling. The steel plate is flat and rectangular, which can be directly rolled or cut from a wide steel strip. The steel type of the thick steel plate is substantially the same as that of the thin steel plate. In all aspects of the product, in addition to bridge steel plates, boiler steel plates, automobile manufacturing steel plates, pressure vessel steel plates and multi-layer high pressure vessel steel plates and other varieties are purely thick plates, some types of steel plates such as automobile beam steel plates (2.5 to 10 mm thick), patterns Steel plates (2.5-8 mm thick), stainless steel plates, and heat-resistant steel plates are intersected with thin plates. Shenzhen galvanized channel steel can be divided into hot-dip galvanized channel steel and hot-blow galvanized channel steel according to different galvanizing processes. Hot-dip galvanized channel steel is an effective metal anticorrosion method, mainly used for metal structural facilities in various industries. on. It is to immerse the rust-removed steel parts in a molten zinc solution at about 440 to 460 ° C, to attach a zinc layer to the surface of the steel member, thereby achieving the purpose of anticorrosion. Currently, the main method of galvanizing the channel steel is hot-dip galvanizing. Another name for Shenzhen Fangtong Wholesale Square Tube, which is the same length of steel pipe. It is made of rolled steel after processing. The strip steel is unpacked, flattened, crimped, welded to form a round pipe, and the round pipe is rolled into a square pipe and then cut to the required length. The small size on the market is usually 6 meters, and the large size is 12 meters. Other specifications can be produced according to the use conditions. Shenzhen Galvanized Fangtong will further process the product according to the actual needs of use, such as cold galvanized square tube and hot galvanized square tube, which can improve the corrosion resistance and rust. For outdoor use, hot plating is relatively easy to rust, and cold plating is generally used indoors. Fangtong is mainly used for welding shelves, curtain walls, decoration, machining, steel structures, daily necessities, etc. As a member of the pipe, it is widely used. Currently, the main method of galvanizing the channel steel is hot-dip galvanizing (hot-dip galvanizing). Hot-dip galvanizing is developed from the older method of hot-dip galvanizing (Develop). Since France applied hot-dip galvanizing to industry in 1836, it has a history of 170 years. . However, in the past 30 years, with the rapid development of cold rolling strip, the hot-dip galvanizing industry has developed on a large scale.
