Steel-frame warehouses are a new type of light-gauge steel building system. Their main steel framework consists of H-section, Z-section, and U-section steel members, while the roof and walls are composed of various panels, as well as doors, windows, cranes, and other components. 1
. Steel structures are lightweight:
Although steel structures have a higher volumetric density, their strength far exceeds that of other building materials. Therefore, under the same loads and conditions, steel structures are lighter than other types of structures, easier to transport and install, and can span greater distances. 2
. Steel has good ductility and toughness
: Good ductility prevents steel structures from sudden fracture due to accidental or localized overloading. Good toughness enables steel structures to better withstand dynamic loads. These properties of steel provide a solid guarantee of the safety and reliability of steel structures. 3
. Steel is closer to being a homogeneous isotropic material:
The internal structure of steel is relatively uniform, very close to that of a homogeneous isotropic material, and it behaves almost entirely elastically within a certain stress range. These characteristics are consistent with the assumptions made in mechanical calculations; therefore, the calculation results for steel structures more accurately reflect the actual stress state. 4
. Steel structures are simple to manufacture, lend themselves well to industrial production, and have a short construction and installation cycle.
Steel structures are composed of various sections and are easy to fabricate. A large number of steel structures are manufactured in specialized metal fabrication plants, ensuring high precision. Prefabricated components are transported to the site for assembly and bolted together; the structures are lightweight, making construction convenient and shortening the construction schedule. In addition, completed steel structures are easy to dismantle, reinforce, or retrofit. 5
. Steel structures offer excellent sealing performance
. Steel structures offer excellent airtightness and watertightness. 6
. Steel structures have high recycling value.
. Key points: High reuse value; relatively economical.
