Detailed Information
Hollow Sections of the AS/NZS 1163 standard are widely used in many fields due to their high strength, durability and versatility. The following are the main application scenarios:1. Building structure
The AS/NZS 1163 Hollow section is widely used in building structures, including residential, commercial and industrial buildings. They can be used in beams, columns, trusses and other load-bearing structural components, with high strength and light weight characteristics, easy to transport and install.
2. Infrastructure projects
In the construction of Bridges, highways, railways and other infrastructure, AS/NZS 1163 hollow sections are used as critical support structures to ensure safety and durability in highly stressed environments. In addition, they can also be used for sidewalks, railings, sign structures and other auxiliary facilities.
3. Mechanical and industrial applications
The hollow section is suitable for mechanical manufacturing and industrial equipment, such as conveying systems, shelves, frames, etc. Its high strength and lightweight properties make it an ideal material for increasing the reliability and installation efficiency of equipment.
4. Energy and Mining
In the oil, gas and mining sector, the AS/NZS 1163 hollow section can be used on oil RIGS, mining equipment and associated delivery systems.
5. Other applications
Public space and urban landscape: used for architectural appearance, decorative structures, etc., to enhance the functionality and aesthetics of public space.
Heavy industry: includes frame structures for manufacturing plants and supporting parts for heavy machinery.
The versatility and reliability of the hollow section of AS/NZS 1163 make it an important material in modern construction and engineering, able to meet a wide range of structural and mechanical needs.
