Appearance and specifications
Various appearance dimensions: The appearance is a rectangular cross-section with various specifications. Different sizes can be customized according to specific needs to adapt to various engineering scenarios.
Light weight: Compared with some other steel materials, it is lighter, convenient to carry and install, and can reduce labor intensity and transportation costs during construction.
Application areas
Building structure: Commonly used in the construction of beams, columns, frames, supports and other components in building structures to provide stable structural support for buildings.
Bridge engineering: It can be used as the main beam of the bridge, load-bearing components, etc., and plays an important role in bridge construction.
Machinery manufacturing: It is used to manufacture components of various mechanical equipment, such as conveyor belts, conveyor pipes, etc.
Q355B galvanized square tube
Material characteristics
Strength and toughness: Q355B is a low-alloy high-strength structural steel with better strength performance than Q235B. Its tensile strength is 470-630MPa, which can withstand greater loads and perform better in projects with higher strength requirements.
Chemical composition: The chemical composition is different from Q235B. Q355B contains a higher manganese element. This difference in chemical composition makes its performance different from Q235B.
Corrosion resistance: It is also galvanized and has good corrosion resistance. It can adapt to a variety of harsh environments and ensure the stability of square tubes during long-term use.
Application field
Construction field: It is suitable for large buildings, high-rise buildings and other construction projects with high structural strength requirements. It can be used to construct the main frame structure of the building.
Bridges and ships: In the field of bridge and ship manufacturing, due to its high strength and good toughness, it can be used as an important structural material to ensure the structural safety of bridges and ships.
Engineering machinery: It is often used to manufacture structural components of various types of engineering machinery to meet the requirements of engineering machinery for material strength and durability during work.
