Materials and Characteristics

Materials: Carbon steel rectangular tubes are primarily made of carbon steel, such as low-alloy steels like Q235 and Q345. These materials offer excellent mechanical and processing properties, meeting the requirements of most engineering applications.

Characteristics:

Excellent Bending and Torsional Strength: The hollow rectangular cross-section design provides a high moment of inertia, resulting in superior bending and torsional strength compared to solid steel sections of the same weight.

Lightweight: Compared to solid steel, carbon steel rectangular tubes are lighter, which significantly reduces the dead weight of the structure.

Ease of Connection and Assembly: The rectangular cross-section facilitates welding, bolting, or riveting to other components, ensuring stable assembly.

Good Processability: Carbon steel rectangular tubes are easily cut, bent, drilled, and otherwise processed, accommodating the needs of various complex structural designs.

Specifications and Dimensions

The specifications of carbon steel rectangular tubes are typically expressed by the dimensions of the cross-section's long and short sides and the wall thickness (e.g., 100mm × 50mm × 5mm). 1. Cross-sectional Dimensions
