Galvanized Steel Tube for Handrail Fencing Guardrail

Our 100mm x 100mm Hot Dip Galvanized Square Steel Pipe is engineered for superior load-bearing capacity and extreme durability in demanding applications. Manufactured from high-grade low-carbon steel (Q235B/Q355B or ASTM A500 Grade B/C), this large-format square tube undergoes a rigorous hot-dip galvanizing process that creates a thick, uniform zinc coating (≥85μm) for maximum corrosion resistance. Ideal for industrial frameworks, warehouse structures, bridge supports, and heavy-duty architectural projects, this pipe combines monumental strength with long-term reliability. The precise 100x100mm dimensions ensure compatibility with standard fittings and easy integration into large-scale designs.

Dimensions: 100mm x 100mm (exact tolerance: ±0.5mm).

Wall Thickness Options: 2.5mm, 3.0mm, 4.0mm, 5.0mm, 6.0mm (custom available).

Material: High-strength low-carbon steel (Q235B, Q355B, ASTM A500 Grade B/C).

Galvanization: Hot-dip galvanized per ASTM A123 (zinc coating: 85μm–120μm).

Length: Standard 6m/12m (custom lengths: 2m–18m).
