I-beam specifications and models

 I-beam specifications and models


Its specifications are expressed by height × leg thickness × waist thickness, and numbers can also be used to indicate the main dimensions of the specifications. For example, No. 18 I-beam means an I-beam with a height of 18 cm. For I-beams with the same height, you can add the corner code a or b or c after the number to indicate, such as 36a, 36b, 36c, etc. It is divided into ordinary I-beams, light I-beams and wide-flange I-beams. According to the height ratio of the flange to the web, it is divided into wide, medium and narrow wide flange I-beams. The specifications produced by the former two are No. 10-60, that is, the corresponding height is 10 cm-60 cm.

Introduction to 20 # carbon steel plate       20 # belongs to superior carbon steel, which complies with GB/T711 standard. 20% of 20 # steel refers to carbon content, which is 0.2%, belonging to low carbon steel. Steel can be divided into low carbon steel, medium carbon steel and high carbon steel. Mild steel - carbon content is generally less than 0.25%; Medium carbon steel - carbon content is generally between 0.25 and 0.60%; High carbon steel - carbon content is generally greater than 0.60%. 　　Domestic and international correspondence of 20 # steel plate: refer to the corresponding steel grade: China's GB/JB standard steel grade is 20, China's Taiwan CNS standard steel grade S20C, Germany's DIN standard material number 1.0402, Germany's DIN standard steel grade CK22/C22. British BS standard steel grade IC22, French AFNOR standard steel grade CC20, French NF standard steel grade C22, Italian UNI standard steel grade C20/C21, Belgian NBN standard steel grade C25-1, Swe...

Rust removal of steel

图片
 Rust removal of steel When steel corrodes, as the volume increases, the steel bars in reinforced concrete will cause the concrete to swell and crack. At present, there are three general rust removal methods as follows. 1) Wire brush to remove rust All the rust on the surface of the steel can be brushed off manually with a steel wire or a semi-automatic wire brush until the metal surface is exposed. This method has low work efficiency and the quality of rust removal cannot be guaranteed. 2) Pickling and derusting Put the rusted steel into the pickling tank, remove the oil and rust respectively until the surface of the component is all iron gray, and clean it up to ensure that there is no residual acid on the surface. This method is more thorough than manual rust removal, with high work efficiency and good effect. 3) Sand blasting to remove rust Clean the rust on the surface of the steel through a sandblasting machine until the surface of the component is off-white, and there must b...

Introduction to angle steel

   Introduction to angle steel        The angle steel can be used to form various stressed members according to the different needs of the structure, and can also be used as a connector between members. It is widely used in various building structures and engineering structures, such as house beams, bridges, transmission towers, hoisting and transportation machinery, ships, industrial furnaces, reaction towers, container racks, cable trench supports, power piping, bus support installation, warehouse shelves, etc. 　　The angle steel is a carbon structural steel used for construction. It is a simple section steel, mainly used for metal components and plant frames. Good weldability, plastic deformation performance and certain mechanical strength are required in use. The raw steel billet for angle steel production is low carbon square steel billet, and the finished angle steel is delivered in the hot rolling forming, normalizing or hot rolling state.
