Box Column Beam

Box column beam is a high-end integrated structural component made of high-grade structural steel with a closed box section, which combines the bending resistance of the beam with the compressive resistance of the column. This component is specially designed to withstand axial pressure (column function), bending moment (beam function), and torque simultaneously. It is the core component of modern high-rise buildings, large-span structures, and industrial projects, especially suitable for scenarios with strict requirements for strength, efficiency, and spatial optimization. It is processed from welded steel plates (such as ASTM A36, A572, or Q355/Q460 grades), and compared to open section or non steel components of the same type, the steel structure box section design has superior comprehensive performance.

The core advantage lies in structural synergy: the box steel structure section can achieve uniform stress distribution, has strong anti buckling ability for compressive loads, and excellent anti bending stiffness for lateral loads, with performance far exceeding traditional beam column combination structures. The application of high-strength steel endows it with excellent strength to weight ratio, allowing for the use of finer component profiles that can easily support various heavy loads from skyscraper floors to stadium roofs while maximizing space utilization. Compared with concrete components, the manufacturing flexibility of steel structure box columns and beams is higher, and the cross-sectional dimensions (rectangular/square) and steel plate thickness can be customized according to project requirements, adapting to diverse engineering scenarios.

Key features include precision manufacturing in the factory: advanced welding processes such as submerged arc welding and gas shielded welding are used to ensure seamless and defect free joints, and quality is verified through non-destructive testing (NDT); Reserved drilling connection points in the modular prefabrication process can simplify the on-site assembly process, shorten the construction period, and reduce errors. The hollow design inside the component can accommodate pipelines or serve as maintenance channels, enhancing functionality and practicality; Through protective measures such as hot-dip galvanizing, epoxy coating, or expansion fireproof coating, a service life of over 50 years can be achieved in harsh environments.

Typical application scenarios include high-rise office buildings, skyscrapers, sports venues, bridge piers, industrial plants equipped with heavy cranes, and modular steel structure buildings. This component simplifies design complexity by balancing integrated functionality, high strength performance, and structural efficiency, providing possibilities for innovative building solutions while meeting the stringent performance standards of large-scale engineering projects.
