Multi-story steel-structure buildings constitute a multi-story building system in which steel serves as the primary load-bearing framework, constructed through standardized factory prefabrication followed by on-site modular assembly. Encompassing a range of functional buildings spanning 2 to 10 stories, this system is widely adaptable to the diverse requirements of various settings—including industrial facilities, commercial complexes, office spaces, warehousing, and public amenities.
Its core advantage lies in the simultaneous realization of structural stability, construction efficiency, and spatial flexibility. By leveraging advanced design standards and construction techniques, it transcends the limitations of traditional architecture to maximize building value in terms of safety, efficiency, environmental sustainability, and scalability; consequently, it stands as the preferred solution for contemporary industrialized construction and urban renewal projects.
Our products focus on "standardized production, modular installation, and full-scenario adaptability." Utilizing high-quality steel—such as Q235B and Q345B—as our core raw materials, we engineer multi-story building solutions that meet rigorous standards while seamlessly integrating load-bearing capacity, seismic resistance, and aesthetic appeal.

- Main Load-Bearing Structure: Centered on a steel frame composed of H-section steel columns and beams, this structure may be paired with rigid frames or bracing systems. Designed to bear all vertical and horizontal loads, utilizing materials that meet strict standards to ensure safety and reliability.
- Connection Nodes: Utilize a combination of high-strength bolted connections and welding. Welds are designed according to specific requirements, and welding consumables are carefully matched to the steel material. The resulting connections are robust, facilitate ease of installation, and effectively transmit internal forces throughout the structure.
- Floor and Roof Systems: The floor system employs reinforced truss floor decks or composite slabs utilizing profiled steel sheeting. The roof system features color-coated steel sheets or sandwich panels supported by C- or Z-section steel purlins; it provides waterproofing, thermal insulation, and wind resistance.
- Enclosure System: Encompasses wall sandwich panels, thermal insulation wool, doors, windows, and other components. Available in a variety of materials, the system offers a blend of thermal insulation, soundproofing, fire resistance, and aesthetic appeal.
- Protection System: Includes both anti-corrosion and fire-protection treatments. Anti-corrosion measures involve the application of primers and topcoats or hot-dip galvanization, while fire protection utilizes fire-retardant coatings or boards.
Characterized by the high strength and toughness of steel, the structure features a light self-weight—resulting in lower foundation costs—and offers robust stability with resistance to earthquakes of magnitude 7-9 and winds exceeding force 12.
Components are prefabricated in the factory and assembled on-site; this process shortens the construction period by 30%-50% compared to concrete structures, ensuring rapid project delivery.
Free from heavy load-bearing walls, the design allows for flexible column spacing and the free partitioning of interior zones; furthermore, it facilitates easy future expansion or renovation, and structural components are reusable.
Steel is 100% recyclable; the construction process generates minimal pollution, promotes energy conservation and waste reduction, and fully aligns with low-carbon sustainability principles.
Component manufacturing strictly adheres to established standards and undergoes rigorous testing, while on-site construction benefits from professional guidance, ensuring full quality traceability.
Offering fully customizable designs, the system is adaptable to a diverse range of applications—including industrial, commercial, and public utility facilities—as well as urban renewal projects.
