Galvanized Steel Tube 50x50mm Square 2.5mm

This 50 × 50 mm square galvanized steel tube combines a substantial 2.5 mm wall with a Z200 hot-dip zinc coating, giving structural fabricators a strong, weather-resistant hollow section. It is commonly specified for racking, mezzanine framing, balustrades, gate structures and equipment supports that need both load capacity and long outdoor service life.

The heavier 2.5 mm wall raises the section’s bending and compression capacity, which makes this size a practical column or beam member for storage systems, conveyor supports, carport posts and heavy handrails. The Z200 zinc layer provides added coating mass for harsher exposure, while the square profile simplifies welding, bolting and corner detailing on site.
