Main Classification of Steel Structures

Hot-Rolled Section Steel

Hot-rolled section steel is formed directly through high-temperature rolling, mainly including H-beams, I-beams, channels, angles and other standard profiles. Featuring uniform material composition, stable mechanical properties and mature section performance, it serves as the primary load-bearing component for industrial and civil steel structures, workshops, bridges, supports and equipment foundations. With mature production technology and complete specifications, it can be directly used for main structural parts such as beams, columns, braces and trusses, characterized by high bearing capacity, good toughness and convenient construction.

Cold-Formed Thin-Wall Section Steel

Cold-formed thin-wall section steel is made of thin steel plates rolled or bent at room temperature, commonly with C, Z, U and similar thin sections. It is lightweight, thin-walled and highly stiff, mainly applied in light steel structural systems. Due to its low self-weight, fast processing and easy standardized installation, it is widely used in enclosure systems, roof and wall purlins, wall beams, secondary structural frames and simple enclosure components of light steel workshops, playing a key role in rapid assembly, weight reduction and cost control.

Welded Built-Up Steel Members

Welded built-up steel members are custom components processed from medium and thick steel plates via cutting, assembling and welding, typically including welded H-beams, box columns, cross columns, T-sections and others. Their section sizes and lengths can be flexibly customized to meet engineering requirements, making them suitable for long-span, heavy-duty, high-rise and special-shaped structures. They are commonly used in key parts such as columns and beams of heavy workshops, steel columns of high-rise buildings, long-span trusses and transfer members, satisfying complex structural stress and architectural design demands.

Steel Pipe Structures

Steel pipe structures use seamless or welded steel pipes, mainly round, square and rectangular hollow sections. With closed sections, they offer uniform stress distribution and excellent torsion and compression resistance, adapting to multi-directional loads. Thanks to superior spatial mechanical performance, simple and elegant appearance and low wind resistance, they are widely applied in spatial trusses, grid structures, stadium roofs, tower frames, pipe gallery supports, steel canopies and landscape structures, showing obvious advantages in long-span spatial structures and aesthetically oriented lightweight buildings.
