Steel Angles Size 200 × 200 mm Thickness 20 m
200 x 200 x 20 Mild Steel Equal Angle Characteristics
Cross-sectional characteristics: This equilateral angle steel has a large cross-sectional area, which is calculated to be about 78.08 square centimeters, and has good structural performance.
Theoretical weight: The weight per meter is about 61.3 kilograms, with strong bearing capacity.
High strength: It is usually made of high-strength steel. Taking Q345 as an example, the yield strength is not less than 345MPa, and the tensile strength is between 470-630MPa.
Good stability: Due to its large size and thick thickness, it has high rigidity and stability.
Good toughness: It has good toughness and can improve the safety of the structure under complex working conditions.
200 x 200 x 20 Mild Angle Steel Production Process
Bill preparation: Select high-quality billets, and strictly test their chemical composition and physical properties to ensure that they meet production requirements.
Heating: Heat the billet to 1100-1250℃ to give it good plasticity for subsequent rolling.
Rolling: The steel billet is gradually rolled into 200×200×20mm equilateral angle steel by multiple passes of large rolling mills. The rolling parameters should be precisely controlled during the rolling process to ensure dimensional accuracy and surface quality.
Cooling: Use appropriate cooling methods, such as air cooling or water cooling, to control the cooling rate to obtain good organizational structure and performance.
Finishing: Perform operations such as straightening, head cutting, surface cleaning, etc. to remove surface defects so that the appearance and size of the angle steel meet the standards.
200 x 200 x 20 Equal Angle Surface Treatment
Hot-dip galvanizing: The angle steel is immersed in molten zinc liquid to form a thick zinc layer, which can effectively prevent the steel from rusting and is suitable for outdoor and humid environments.
Painting: Apply anti-rust paint, anti-corrosion paint, etc. to provide additional protection. At the same time, different colors of paint can be selected as needed to meet the requirements of decoration and identification.
Phosphating: A phosphating film is formed on the surface of the angle steel to improve the adhesion and corrosion resistance of the coating. It is usually used as a pretreatment process before painting.
