Product Presentation
Multi-span steel structure buildings are architectural forms with steel as the main load-bearing structure, composed of multiple span units. Their framework is constructed using steel beams, steel columns and other steel structure components. The roof and walls commonly use lightweight materials such as profiled steel sheets and color steel sheets, featuring high strength, low self-weight and good seismic resistance. The building space is spacious, with designs featuring few or no columns, allowing for flexible internal layout and the ability to meet different usage requirements. In terms of construction, prefabricated assembly methods are often adopted, with components precisely manufactured in factories and quickly assembled on-site, shortening the construction period, being environmentally friendly and facilitating later renovations and dismantling. They are widely used in industrial and civil construction fields.

Purpose
Industrial production scenarios
Production workshop: Provides a large space working environment for
industries such as mechanical manufacturing, automotive assembly,
and electronic processing. The open and column-free space is
convenient for placing large equipment and arranging assembly
lines. The high strength of steel components can withstand the load
of production equipment, meeting the needs of heavy industry
production, such as heavy machinery processing workshops. The
multi-span structure is used to accommodate large machines and
cranes in multi-span structures.
Warehousing and logistics: As a warehouse for storing goods, the
multi-span large space can store raw materials and finished
products in separate categories. Combined with shelves and stacker
cranes, it improves storage efficiency. In logistics transfer
warehouses, it is convenient for cargo loading and unloading, as
well as the assembly line for sorting. The durability and sealing
of the steel structure can protect the goods from moisture and
rust, suitable for storing various types of materials.
Commercial and public building scenarios
Convention center: Multi-span structure creates an ultra-large
column-free exhibition hall, facilitating the holding of
large-scale exhibitions and events. The flexible space can be
quickly divided into exhibition areas, stage areas, etc., according
to the needs of the event. The large span of the steel building can
meet the needs of gatherings of thousands of people and the display
of large exhibits (such as construction machinery, ship models),
improving the utilization rate of the venue.
Sports venue: Used for building stadiums, swimming pools, etc. The
large span covers the competition area, ensuring unobstructed views
for spectators. The lightweight and high-strength steel structure
reduces the requirements for the foundation of the building, and
can also adapt to complex shapes, such as domes and curved roofs,
creating iconic sports buildings. It also has good seismic and wind
resistance performance, ensuring safety in use.
Agriculture and special scenarios
Agricultural facilities: As modern agricultural greenhouses and
breeding factories, multi-span spaces can accommodate planting
racks and breeding equipment. The transparent walls and roof
designs of the steel structure (such as with solar panels)
facilitate light penetration for crops and the growth of livestock.
The steel is corrosion-resistant and rust-proof, suitable for the
humid and moldy environment of agriculture, extending the lifespan
of the building.
Emergency and disaster relief buildings: In emergencies, they can
be quickly built as temporary shelters or material storage
warehouses. Prefabricated components can be urgently dispatched and
assembled, providing living and storage space in a short time. In
post-disaster reconstruction, they can also be used as transitional
schools or medical stations. Their flexible space can be used to
arrange classrooms and treatment areas, meeting emergency needs.
