Steel Tube Frame Single Slope Structure (3-6 meter span) This design adopts a steel tube frame as the supporting framework. Roof purlins are directly connected to the steel tube frame, forming a sloped roof. Rectangular steel tubes are used as column and beam materials. For example, a single, simply supported beam spanning 6 meters generally uses a rectangular tube like 60x120x4 as the column and beam material. Suitable for: This structure is suitable for small warehouses, storage rooms, and other applications where ceiling height requirements are not high. The typical slope is 10% of the span, with a single slope flowing backward. Important: concrete rainwater drainage must be done around the warehouse; otherwise, building settlement is easy to cause.

02

Steel Tube Frame Triangular Truss Structure (6.5-15 meter span) This design adopts a steel tube frame to support triangular trusses. The trusses act as the primary load-bearing components, and roof purlins are connected to the trusses. Steel tubes are used for the triangular truss components, which include: top chord, bottom chord, vertical struts, and diagonal braces. The bottom chord experiences the greatest stress, so the material used is also the most substantial. Suitable for: This structure is suitable for medium to small warehouses with a moderate span. Pay attention to the stability of the trusses, the strength of the connection nodes, and the roof system. Details such as connection plates, stiffening plates, welding thickness, and weld bead width will all affect structural stability.

03

Steel Tube Frame Circular Truss Structure (15-35 meter span) This design adopts a steel tube frame to support circular trusses. The trusses bear the primary load. The typical rise is 15% of the span. A bottom chord tension member (tie bar) must be included; without it, the columns will spread outwards, causing the warehouse to collapse. Steel tubes are used, and consider using high-strength steel to reduce weight. Generally, circular tubes are used; rectangular tubes are used less often. Suitable for: This structure is suitable for warehouses where high space utilization is required; the arched roof can provide a greater clear height. The stress analysis, node connection design, and overall stability of the circular truss are comparatively economical and can save construction costs compared to heavy-duty steel structures.

04

H-Steel Heavy-Duty Steel Structure (20-45 meter span) This design adopts H-steel as the primary load-bearing components, forming a framework structure. The H-steel type, material, and strength are important. Typical rectangular H-steel sections include sizes such as 400x200 or 350x175 and 500x250. Suitable for: This structure is suitable for large warehouses, logistics centers, and other applications requiring long spans. The H-steel layout, connection methods, support settings, and overall stability calculations must be performed. Steel structures that have not been calculated are easily prone to twisting and deformation, or even collapse.

05

Space Truss Structure (No columns, similar to a gas station canopy) This structure is comprised of a spatial mesh-like structure of steel tubes or steel cables. Roof panels are directly connected to the mesh, without the need for columns. It typically uses high-strength steel tubes connected with high-strength bolts. Suitable for: This structure is suitable for applications requiring extremely open space, such as gas stations, exhibition halls, and large logistics centers. The design and construction of space truss structures are complex and require professional technical personnel.
