50mm x 50mm x 3mm Mild Steel Box Section - Rectangular Hollow Tube for Welding, Fabrication & Construction - Heavy Duty Steel Square Tube (3mm Thickness) - Linear Metre

50mm x 50mm x 3mm Mild Steel Box Section: A Versatile Choice for Structural Projects

The 50mm x 50mm x 3mm mild steel box section is a robust and versatile material, ideal for various structural, fabrication, and construction applications. This box section, crafted from high-quality mild steel, combines strength and ease of use, making it a popular choice among engineers and fabricators.

Material and Grade

Manufactured from E220-grade mild steel, this box section provides excellent mechanical properties. E220 steel is known for its strength and durability, making it suitable for heavy-duty applications where structural integrity is paramount.

Key Specifications

• Dimensions: The height and width of the box section are 50mm, with a thickness of 3mm, offering a square profile.
• Weight: The steel section weighs 4.47kg per metre, providing a solid and reliable foundation for any construction or fabrication project.

Performance Characteristics

1. Formability: While the formability of this mild steel box section is considered poor, it can still be manipulated using appropriate equipment. It is better suited for applications that do not require extensive bending or reshaping.

2. Weldability: One of the standout features of this mild steel box section is its excellent weldability. The E220 grade steel allows for easy and efficient welding, making it a perfect material for welded structures and frames.

3. Machinability: The machinability of this product is also excellent, ensuring that the material can be easily cut, drilled, and processed without compromising its structural integrity.

4. Corrosion Resistance: Corrosion resistance is poor due to the mill finish and lack of additional protective coatings. Therefore, it is recommended that this steel box section be treated with appropriate protective measures, such as painting or galvanizing, especially when used in outdoor or corrosive environments.

5. Finish: This box section comes in a mill finish, giving it a raw, industrial look. While this is perfectly functional for internal use, it may require additional finishing, such as polishing or painting, for aesthetic purposes or protection in exposed settings.

Applications

This 50mm x 50mm x 3mm mild steel box section is suitable for a wide range of applications, particularly in construction, metal fabrication, and engineering projects. It is commonly used for:

• Frames: Ideal for creating sturdy frameworks for structures, vehicles, and furniture.
• Supports and Bracing: Its strength makes it a popular choice for support beams and bracing in construction.
• Gates and Fencing: The box section is also frequently employed in the fabrication of gates, fencing, and handrails due to its weldability and strength.

Conclusion

The 50mm x 50mm x 3mm mild steel box section is a reliable material for a variety of structural and fabrication tasks. Its excellent weldability and machinability, combined with the strength of E220-grade steel, make it an ideal choice for both small and large-scale projects. However, it is important to address its poor formability and corrosion resistance by applying the necessary protective coatings when used in challenging environments.
