Mild Steel Box Section/Square Hollow Section

Product Type - Steel Pipe

Mild Steel Box Section, also known as Square Hollow Section (SHS), refers to a type of hollow structural section made from mild steel. It is characterized by its square or rectangular shape with uniform wall thickness. Mild steel box sections are commonly used in construction, engineering, and manufacturing industries due to their versatility, strength, and affordability.

The dimensions of mild steel box sections can vary, with different thicknesses, widths, and lengths available to meet specific project requirements. The standard grades of mild steel used for box sections include S235, S355, and ASTM A36. They are typically produced through cold-forming processes, where flat steel plates are formed into the desired shape and then welded together to create a hollow section.

Mild steel box sections have a wide range of applications. They are commonly used in structural frameworks, supports, columns, and beams in buildings. They are also used in the manufacturing of furniture, storage racks, fencing, handrails, and various types of framework for machinery or equipment.

Mild steel box sections offer good strength-to-weight ratio, making them suitable for load-bearing structures. They can be easily cut, drilled, and welded, allowing for easy fabrication and installation.

It’s important to note that mild steel box sections are susceptible to corrosion, especially in outdoor or high-moisture environments. Protective measures such as painting, galvanizing, or using stainless steel box sections can be employed to enhance their corrosion resistance and durability. Regular maintenance and inspections are also necessary to ensure the longevity and structural integrity of mild steel box sections.
