This article will analyze Australian Standard Square Tube C350 and its implementation standard AS from multiple perspectives to help readers gain a deeper understanding of this product.
Basic characteristics of Australian Standard Square Tube C350
Australian Standard Square Tube C350 is a high-strength cold-bent hollow steel section. The "C350" in its name represents its minimum yield strength of 350MPa.
This square tube has the following characteristics:
High strength-to-weight ratio, suitable for load-bearing structures
Excellent corrosion resistance
Good weldability and processability
High dimensional accuracy and good surface quality
As a steel supplier, GNEE Group has long supplied various steel products that meet AS standards, including Australian Standard Square Tube C350.
Detailed explanation of AS implementation standards
Australian standard AS1163 is the main implementation standard for Australian standard square tubes. This standard clearly stipulates the technical requirements for cold-formed structural hollow steel sections:
| items | Requirement |
| Chemical composition | Strictly control the content of carbon, manganese, phosphorus, sulfur and other elements |
| Mechanical properties | Yield strength ≥ 350MPa, tensile strength 430-550MPa |
| Dimensional tolerances | Outer diameter, wall thickness, length, etc. are strictly regulated |
| Surface quality | No defects such as cracks and folds |
Application
- Australian standard square tube C350 is widely used in many fields due to its excellent performance:
- Building structure: beam and column system for buildings such as factories and warehouses
- Machinery manufacturing: as equipment frame and support structure
- Infrastructure construction: auxiliary structure in bridges, tunnels and other projects
- Mining equipment: heavy-load support and protective structure
