50mm x 30mm x 2.5mm Mild Steel Box Section - Rectangular Steel Tube for Fabrication, Welding & Construction - Durable E220 Grade Metal (2.5mm Thickness) - Linear Metre

50mm x 30mm x 2.5mm Mild Steel Box Section: A Reliable Choice for Structural and Fabrication Projects

The 50mm x 30mm x 2.5mm mild steel box section is a highly versatile material, well-suited for a wide range of structural, fabrication, and engineering tasks. Manufactured from high-quality E220-grade mild steel, this rectangular hollow section provides strength and durability, making it an ideal choice for demanding construction applications.

Material and Grade

Crafted from mild steel, this box section is made to the E220 standard, known for its excellent mechanical properties. E220 steel is widely used in construction due to its robustness, providing strength without sacrificing ease of use in fabrication processes.

Key Specifications

• Dimensions: With a width of 50mm, a height of 30mm, and a thickness of 2.5mm, this steel box section features a rectangular profile suitable for numerous applications.
• Weight: Weighing 2.97kg per metre, the mild steel section offers a good balance between strength and manoeuvrability for various tasks.

Performance Features

1. Formability: The formability of this box section is poor, which means it is not easily bent or reshaped without specialized equipment. However, it is ideal for applications where maintaining a rigid, structural shape is critical.

2. Weldability: One of its standout qualities is excellent weldability, allowing for smooth and strong joints when welding. This feature makes the section ideal for projects that require sturdy welded structures, from frameworks to bracing components.

3. Machinability: With excellent machinability, this steel section can be cut, drilled, and shaped with ease, ensuring that it meets the precision requirements of your project without compromising the material’s integrity.

4. Corrosion Resistance: Like many untreated mild steel products, the corrosion resistance of this box section is poor. While suitable for internal use, it is recommended to apply coatings such as paint or galvanization to prevent rust if the material is used in outdoor or exposed environments.

5. Finish: Featuring a mill finish, the surface of this box section retains a raw, industrial appearance. This finish can be left as-is for projects where aesthetics are less important or further treated to achieve a polished look.

Applications

This 50mm x 30mm x 2.5mm mild steel box section is widely used across various industries due to its strength, weldability, and machinability. Common applications include:

• Structural Frameworks: Its robust profile makes it perfect for creating frameworks in both commercial and domestic construction projects.
• Fabrication Projects: The ease of machining and welding makes this section ideal for fabrication, whether for industrial machinery, automotive parts, or bespoke metalwork.
• Gates, Railings, and Fencing: Frequently used in the fabrication of gates and railings due to its strength and ability to be easily welded into custom shapes.
• Bracing and Supports: It also functions well as a support or brace in metal structures, adding stability without excess weight.

Conclusion

The 50mm x 30mm x 2.5mm mild steel box section is a reliable choice for professionals working on fabrication, construction, and structural projects. Its combination of E220-grade steel, excellent weldability, and superior machinability makes it highly versatile. However, for outdoor or corrosive environments, applying a protective coating will help extend its lifespan and maintain its structural integrity. Whether for creating frames, supports, or custom metalwork, this steel section is designed to deliver strength and durability in every project.
