AS/NZS 1163 250 – Cold-formed steel. An Australian Standards Equivalency.
Q235 Chinese Steel used in the structure is equivalent to AS/NZS 1163 C250 and AS/NZ3679.1.
Yield Strength 250MPa
Tensile Strength 350-500MPa
0.22% Carbon content
The C250 (250 MPa) designations refer to the minimum yield strength of hollow section steel.
AS/NZS 1163 is the Australian/New Zealand Standard for Cold-formed structural steel hollow sections. This Standard specifies the requirements for the production and supply of cold-formed, electric resistance-welded, steel hollow sections used for structural purposes. These standards define the material composition, strength requirements, dimensions, and manufacturing processes to ensure quality and performance,
AS/NZS 1163 C250 hollow sections are essential components in the structural engineering and construction industries. Adherence to AS/NZS 1163 is crucial for maintaining safety and compliance in structural applications. Our manufacturing process involves cutting, bending and shaping, holing, chamfering to meet AS/NZS 1163 C250 certification requirements.
AS/NZS 1163 C250 represents cold-formed structural steel hollow sections with 250 MPa minimum yield strength, and no impact test required.
Manufacturing Processes and Quality Control
AS/NZS 1163 C250 hollow sections are manufactured through a hot-rolling processes whereby the steel is heated to a high temperature and then passed through a series of rollers to form the desired shape and dimensions. After rolling, the sections undergo strict quality control measures such as dimensional inspections, mechanical testing, and surface examination to ensure compliance with the AS/NZS 1163 standard. Rigorous quality control protocols are implemented throughout the manufacturing process to maintain consistency and reliability.
The following profiles are used in the production of our container dome shelter structures.
- Rectangular Hollow Section (RHS) – (base rails)
- Circular Hollow Section (CHS) – (roof frame structure)
- Square Hollow Section (SHS) – (roof frame structure)
These sections are normally electric resistance welded and are used for structural purposes and engineering applications. the standard applies to both welded and seamless hollow sections in circular, square, and rectangular shapes.
Cold-formed Steel.
Key Properties of Cold-Formed Steel These materials are specified by Australian standards
- Superior strength, durability and versatility
- Lightness in weight
- High strength and stiffness
- Ease of prefabrication
- Fast and easy assembly and installation
- Termite-proof and rot-proof
- Non-combustible
- Recyclable
- Durability, reliability
- Well-suited for regions with high winds or seismic activity
- Cost-effectiveness
In the production of Quality Domes Direct container dome shelter structures, Cold Formed Steel (CFS) shaping processes (rolling, drilling, pressing, stamping, bending at room temperature.) refers to how the hollow sections of steel are manufactured. Steel truss frames (CSH), purlins (CSH), cross-bracing tubes (CSH), base rails (RHS) anchor plates and associated fittings fall into this category.
The production process involves cold bending steel plates or coils into hollow tubes and welding them together. This process produces hollow sections of steel with high strength-to-weight ratios, high yield and tensile strength resulting in strong, lightweight and versatile steel sections, ensuring durability and stress tolerance under a variety of load conditions.
