With abundant experience, we warmly welcome you to wholesale cheap products in stock here and get free sample from our factory. For price consultation, contact us.
The 50x50 box section, a popular size of square hollow section (SHS), is a fundamental building block in modern fabrication and construction. Known for its excellent strength-to-weight ratio and clean, geometric profile, this mild steel hollow section is prized for its versatility and structural integrity in a vast array of applications.
Crafted from high-quality mild steel, our 50mm box section steel is available in various wall thicknesses (e.g., 3mm, 4mm, 5mm) to meet different load-bearing requirements. For projects requiring enhanced corrosion resistance, we also offer a galvanised box section version, where a protective zinc coating is applied to ensure longevity in harsh or outdoor environments.

Hollow Structural Sections (HSS) are high-strength, cold-formed steel tubing with a square, rectangular, or round profile. Renowned for their exceptional strength-to-weight ratio, clean aesthetic lines, and versatile fabrication properties, HSS have become a fundamental component in modern construction, architecture, and manufacturing.
