150mm x 150mm x 5mm Mild Steel Square Box Section

The thickness of a mild steel box section refers to the gauge or thickness of the steel used to create the box's walls. The box section, also known as a hollow structural section (HSS), typically comprises four sides—two parallel longer sides and two parallel shorter sides—that form a rectangular or square shape.

The required thickness for a mild steel box section depends on the structural load it needs to bear, the intended application, and any safety considerations:

Structural support: For load-bearing structures or applications requiring substantial strength, thicker gauge mild steel box sections are generally preferred to provide adequate support and stability.

Non-load-bearing applications: Thinner gauge box sections might be suitable for non-load-bearing purposes, such as decorative elements or lightweight structures.

Consulting with an engineer or someone experienced in structural design can help determine the right gauge or thickness of a mild steel box section for your intended use.
