Q235B galvanized round tube
Chemical composition: The carbon content of Q235B is between 0.14% and 0.22%.
Mechanical properties: Q235B has good weldability and plasticity, and is suitable for general building structures.
Application areas: Suitable for general small structures or non-critical components, economical and practical.
Advantages of galvanizing: Galvanizing increases the service life of steel and reduces subsequent maintenance costs, especially suitable for humid or chemically corrosive environments.
Q355B galvanized round tube
Chemical composition: The carbon content of Q355B is between 0.12% and 0.20%.
Mechanical properties: Q355B is a high-strength steel suitable for structures with heavy loads.
Application areas: High strength, suitable for projects with heavy weight, good ductility.
Advantages of galvanizing: Similarly, galvanizing increases the service life of steel and reduces subsequent maintenance costs, especially suitable for humid or chemically corrosive environments.
