Component Specifications

Definition
Steel base material specifically manufactured for structural hollow sections (SHS), which are cold-formed or hot-rolled steel profiles with hollow cross-sections. This material provides the fundamental mechanical properties required for load-bearing applications in machinery frames, structural supports, and industrial equipment. The base steel undergoes controlled chemical composition and thermal processing to achieve optimal strength-to-weight ratios, weldability, and corrosion resistance.
Working Principle
The steel base material serves as the foundational element for structural hollow sections, providing tensile strength, yield strength, and ductility through its metallurgical composition and processing. When formed into hollow sections, the material distributes mechanical stresses efficiently across its cross-section, offering superior bending and torsional resistance compared to solid sections of equivalent weight.
Materials
Carbon steel grades (S235, S275, S355) with controlled carbon content (0.17-0.22%), manganese (0.50-1.60%), and trace elements. May include micro-alloyed grades with vanadium or niobium for enhanced strength. Available in hot-rolled or cold-formed conditions with specified yield strengths from 235 MPa to 460 MPa.
