Overview

About this mild steel box section

This galvanized mild steel box section with rectangular dimensions and a thickness of 3mm provides structural support with improved corrosion resistance. It is suitable for outdoor applications or environments where exposure to moisture and corrosive elements is a concern. The reduced weldability and machinability compared to non-galvanized steel should be taken into consideration during fabrication.

  1. Material: Mild Steel - Commonly used in construction and manufacturing due to its strength and cost-effectiveness.

  2. Formability: Poor - Mild steel, while strong, may be less malleable or easily shaped compared to some other materials.

  3. Weldability: Poor - The welding characteristics may be affected by the galvanization process. Specialized welding techniques may be required.

  4. Machinability: Poor - The galvanization process can make the material more challenging to machine compared to non-galvanized mild steel.

  5. Shape: Box Section - The cross-sectional shape of this steel component is rectangular, providing structural support in a variety of applications.

  6. Corrosion Resistance: Good - The galvanized coating provides a protective layer that enhances the corrosion resistance of the mild steel, making it suitable for outdoor or corrosive environments.

  7. Finish: Galvanised - The box section has a galvanized finish, indicating that it has undergone a process to apply a protective zinc coating.

  8. Grade: S235 - A specific grade classification for the mild steel, indicating its structural properties.

  9. Weight/Metre (Kg): 7.32 - This figure represents the weight of one meter length of the galvanized box section, which is 7.32 kilograms.
