Main Uses of Steel Structure Frame Buildings

I. Industrial Production
Standard Production Plants: Machinery processing, equipment manufacturing, hardware processing workshops; H-beam steel frames offer strong load-bearing capacity and customizable floor height.

Warehousing and Logistics Warehouses: E-commerce warehouses, cold chain warehouses, material storage warehouses; large spans without columns, convenient for forklift operation and goods stacking.

Livestock Sheds: Chicken coops, cattle sheds, livestock industrial parks; lightweight steel frames provide ventilation and moisture protection, and are quick to construct.

Large Workshops: Car showrooms, heavy-duty assembly workshops, steel structure processing plants.

Multi-story Industrial Park Buildings: Biomedical and electronic science and technology innovation industrial parks; multi-story steel frames utilize land efficiently.

II. Commercial and Trade
Large shopping malls, shopping streets, and mixed-use commercial complexes; large atriums and cantilevered corridors are achieved using steel frames.

Street-front shops and modular steel structure buildings in commercial streets.

Car dealerships and brand showrooms; transparent facades and spacious display areas.

Hotels, apartments, and mixed-use commercial office buildings.

III. Office and Business Buildings
High-rise Grade A office buildings and corporate headquarters buildings (steel frame - Core Tube System)
Industrial Park Office Buildings, R&D Centers, Science and Technology Incubation Buildings
Government Office Buildings, Independent Corporate Office Buildings

IV. Public Cultural and Sports Venues
Sports Venues: Football Fields, Gymnasiums, Swimming Pools, with Extra-Large Span Roof Steel Frames
Exhibition Centers, Expo Halls, Trade Fair Exhibition Halls, Large Unobstructed Indoor Spaces
Cultural Venues: Art Museums, Theaters, Libraries, Cultural and Art Centers
