Structural steel structure building system
Lu Li provides you with structural building solutions.
1. Cold-formed steel door frame
The portal frame is mainly light steel structure. It has two forms-lattice rigid frame and solid abdominal rigid frame.
The door frame system has the characteristics of mature and reliable system and wide adaptability.
The door frame system uses high-strength galvanized purlins to extend the service life of the building, and is the most widely used building system.
2. Large column structure:
Because the substructure adopts a truss purlin system, the large-spacing system can be expanded more in the row spacing direction; the indoor space looks more beautiful and sparse, mainly used for logistics warehouses and supermarket buildings.
3. Multi-layer structure
Multi-storey systems are used in parking lots, office buildings, schools and industrial buildings' multi-storey auxiliary facilities to meet more architectural needs.

Steel structure building component system: the main components H steel connected to each other, the secondary components, the roof and wall panels (or sandwich panels) and various other building components. These buildings can provide different structural and non-structural additions, such as skylights, wall lights, turbine vents, ridge fans, shutters, roof monitors, doors and windows, trusses, mezzanine floors, canopies, bridge cranes (if required) , Insulation materials, etc. , According to customer requirements. All steel structure buildings are custom-designed, with lighter weight and higher strength. Therefore, in the past four decades, the design of steel structures has become more flexible, durable and adaptable, which makes steel one of the preferred materials for building structures.
Advantages of steel structure warehouse
1) Compared with civil buildings, it has the advantages of convenient construction, low cost, time-saving, labor-saving and convenient transportation.
2) The steel structure makes the house resistant to strong winds of 120 km/h and magnitude 7 earthquakes.
3) It has good fire and heat insulation properties.
4) Prevent worms and ants. All steel structures have been painted and rust-proofed, and can be used normally for more than 15 years without construction waste.
5) Environmental protection materials, which can be disassembled and assembled six times.
6) Beautiful appearance, different colors of walls, roof and steel structure.
7) The horizontal concrete floor can meet the foundation requirements.
