Manufactured from EN3B-grade mild steel, this square bar offers excellent weldability, machinability, and formability, making it suitable for a range of projects requiring precision and strength.

Material and Grade

Made from EN3B mild steel, this square bar meets industry standards for strength and durability. EN3B is a low-carbon mild steel, known for its excellent mechanical properties, making it easy to work with and ideal for both small-scale and large-scale projects.

Key Specifications

• Size: The bar is 12.7mm x 12.7mm (equivalent to 1/2 inch in imperial measurements), making it suitable for applications requiring precise dimensions and a compact, strong profile.
• Weight: Each metre of the bar weighs 1.28kg, providing solid strength while being easy to handle and process.

Performance Characteristics

1. Weldability: The weldability of this square bar is excellent, allowing for strong and secure weld joints. It’s particularly useful for projects involving metal frameworks or structures where welding is a key part of the process.

2. Formability: With excellent formability, the mild steel bar can be shaped or bent with ease, making it a flexible material for custom fabrication, metalworking, or construction projects that require different shapes and designs.

3. Machinability: The excellent machinability of this steel bar allows for easy cutting, drilling, and shaping to meet specific project requirements. Whether you're modifying the bar for intricate designs or simply cutting it to size, this material is highly adaptable to machining processes.

4. Corrosion Resistance: While the corrosion resistance of mild steel is poor, the bar's bright finish provides a smooth surface that is ready for additional coatings, such as paint, galvanising, or protective treatments. These coatings can improve the corrosion resistance and prolong the life of the material in outdoor or moisture-exposed environments.

Applications

This 1/2" (12.7mm) mild steel square bar is suitable for a wide range of applications, thanks to its strength, precision, and versatility:
