Channel steel letters indicate content

Issuing time: 2018-12-09 14:23:26


Many people have limited understanding of angle iron (Find out), but today we first put down this and other issues (Emerson) such as steel and angle iron (zhū rú) and take a look. " Channel steel letters indicate specific gravity ". I hope you can understand more. At the same height, light channel steel (Steel) has narrower legs (LEG), thinner waist (yāo), and lighter weight than ordinary channel steel. . 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. Shenzhen cold plate wholesale cold rolled coils are made of hot rolled coils at room temperature and below the recrystallization temperature, including plates and coils. Many domestic steel mills such as Baosteel, Wuhan Iron and Steel, Anshan Iron and Steel can produce them. The ones delivered in sheets are called steel plates, also called box plates or flat plates; those with long lengths and delivered in coils are called steel strips, also called coil plates. Has good durability, longer life compared to galvanized steel; has good heat resistance, is less prone to discoloration at high temperatures compared to galvanized steel; has similar processability and spraying performance to galvanized steel; Shenzhen floor slab wholesale is also called composite floor, floor slab or steel slab, Wancheng composite slab, profiled steel plate. Floor slab is an important supporting product for steel structure building, mainly divided into open floor slab, closed floor slab Plate, necked dovetail floor plate, reinforced truss floor plate. It is made of galvanized steel sheet through roll cold bending, and its cross-section is V-shaped, U-shaped, trapezoidal or similar waveforms. It is mainly used as a permanent template and can also be selected for other purposes. Shenzhen galvanized sheet wholesale refers to a steel plate with a layer of zinc plating on its surface. Galvanizing is a commonly used economic and effective anti-corrosion method. About half of the world's zinc output is used for this process. Galvanized sheet can be divided into hot-dip galvanized steel sheet, alloyed galvanized steel sheet, electro-galvanized steel sheet, single-sided and double-difference galvanized steel sheet according to production and processing methods. The main importing countries are China, Japan, and Germany. , Russia, France, South Korea, etc. No. 18-40 is a large channel steel, and No. 5-16 is a medium-sized channel steel. Imported channel steel is marked with actual specifications and relevant standards. The import and export order of channel steel is generally based on the specifications required in use after the corresponding carbon (C) steel (or low alloy steel) steel number is determined. Except for the specification number, channel steel has no specific composition and performance series.

① The chemical composition is represented by the symbol of the international chemical element and the national symbol, and the proportion of the composition is represented by the Arabic letters:
Such as: China (CHINA), Russia 12CrNi3A

② The fixed (fixed) letters and digits are used to indicate the series or numbers of steels; for example, the United States (USA), Japan, 300 series, 400 series, and 200 series;

③Composition number is composed of Latin letters and sequence, which only indicates the purpose. (Tōng guò) Introduction of this article. I believe that everyone has a certain understanding of "Steel letter indicates the proportion".
