Core Advantages
EN 10210 steel tube hollow sections are manufactured using hot finished seamless or welded steel tube. These hollow sections are also known as structural steel tubes and are used in construction and engineering applications.
Physical Characteristics:
- High strength and durability: EN 10210 steel hollow sections are strength and durability as they are made from high-quality steel.
- Resistance to corrosion: These hollow sections are resistant to corrosion, making them an excellent choice for outdoor applications.
- High stiffness: The hollow sections are highly stiff and can resist bending, making them suitable for structural applications where high load-bearing capacity is required.
- Excellent weldability: The tubes can be welded easily, making it easy to create structures of varying shapes and sizes.
Application Advantages:
- Structural Applications: EN 10210 steel tubes are widely used in structural applications such as bridges, buildings, towers, and frames, where high load-bearing capacity, stiffness, and durability are required.
- Construction Industry: EN 10210 steel hollow sections are used in the construction industry for gates, fences, barriers, and security systems.
- Industrial Applications: They are also used in industrial applications such as platforms, mezzanines, and staircases where strength, durability, and corrosion resistance are required.
- Automotive Industry: Steel hollow sections can also be used in the automotive industry for the manufacturing of parts and components due to its high strength, durability and resistance to corrosion.
In conclusion, the physical characteristics and application advantages of EN 10210 steel tube hollow sections make it an excellent choice for structural and engineering applications requiring high strength, durability, and corrosion resistance.
