What Is a Modular Steel Frame?

The modular steel frame refers to a versatile, prefabricated load-bearing skeleton made from high-grade steel components, primarily columns and beams, assembled with precision in controlled environments. Leveraging hot-rolled profiles and advanced connection methods (bolted/welded), these systems offer modularity and scalability absent in traditional concrete or timber frameworks. The result is optimal performance in seismic safety, wind-load resistance, and environmental impact—supported by real-world deployment in industrial, petrochemical, and commercial applications.

Typical Section Forms: H-beam, I-beam, Box-column, Tubular
Surface Treatments: Hot-dip galvanizing, epoxy/polyurethane painting, fluorocarbon spray
Process Control: Automated CNC cutting and welding for dimensional accuracy
Welding Standards: AWS D1.1, EN ISO 5817
