Steel columns are a key element of the building structure and have the important task of transferring vertical loads and effectively directing enormous forces from roofs, floors, and the external environment to the foundation. As a professional steel structure manufacturer, we understand the art of producing steel columns for building structures, transforming high-strength steel into vital support elements that ensure the safety and functionality of buildings through precise sheet metal processing, creating a solid foundation for industrial facilities, shopping centers, warehouses, and public buildings.

The main advantage of steel columns is their excellent strength-to-weight ratio. Compared to concrete columns, the cross-sectional area of a steel column bearing the same load can be reduced by 40–60%, significantly freeing up practical space within the building. The characteristics of industrial prefabricated structures depart from traditional construction methods. We precisely process the connecting plates at the ends of the columns using laser cutting to ensure the screw hole positioning is accurate to within ±0.5 mm, and we create complex structures using numerical control bending. We also use laser cutting to process the connecting plates at the ends of the columns (so that the positioning accuracy of the bolt holes is ±0 mm), create complex box-shaped column cross-sections by CNC bending and ensure full fusion of the welds by automatic welding (submerged arc/shielded gas). Ultrasonic flaw detection testing is used to ensure that the section resistance of the column body exceeds that of the base material. This precision manufacturing enables steel columns to span kilometres in skyscrapers, support loads of up to 100 tonnes in industrial plants and create long spans of column-free space in large exhibition halls, thus completely redefining the limits of architectural possibilities.

The performance of steel columns directly determines the safety of a building throughout its life cycle. We implement customised manufacturing strategies for different application scenarios:

  • Wind and earthquake protection: the thickness of the flange plate and the arrangement of energy-consuming nodes make steel columns the first line of defence against hurricanes and seismic forces. Ductility absorbs more than 80% of seismic energy.

  • Large plants have excellent resilience thanks to box-shaped columns and internal longitudinal partitions that prevent local buckling and support 1. 000 tonnes of production equipment.

  • Protection from corrosive environments: waterfront buildings use hot-dip galvanised steel columns or stainless steel composite cladding to provide 50 years of maintenance-free corrosion protection.

  • Fire protection and safety assurance: intumescent fire coatings or concrete infill methods can meet three-hour fire resistance requirements, providing critical time for staff evacuation. Critical time for evacuation.

The industrialised prefabrication of steel columns is helping to modernise the construction industry. We use advanced manufacturing technology:

  • Digital scanning: Generate processing data directly from the BIM model and avoid dimensional deviations on site

  • Intelligent cutting and unloading: High-performance plasma cutting of 40 mm thick steel plate, minimising welding distortion.

  • Robotic welding: Constant parameter control of 20 metre long columns with continuous weld bead, eliminating manual variations.

  • Modular pre-assembly: Column sections integrated with columns and tubular supports are completed in the factory, reducing on-site construction time by 30%.

  • This not only shortens construction time by over 50%, but also saves 15% material through material optimisation and lightweight construction, which together with waste recycling makes steel columns a major positive point in the life cycle analysis.

As professional manufacturers of architectural steel columns, we combine structural mechanics, material technology, and precision sheet metal fabrication to create structural solutions that offer the exceptional load-bearing capacity and aesthetic qualities required for modern buildings. We oversee every stage of the manufacturing process, from cutting the raw material to surface treatment, ensuring that each steel column is crafted to the highest standards.
