Galvanized Steel Round Tube 2 inch 2.5mm

This 2 inch (48.3 mm OD) galvanized round steel tube with a 2.5 mm wall is a versatile hollow section for railings, posts and mechanical framing. The round profile sheds water evenly and delivers consistent strength in every direction, which is why it appears so often in handrails, pipe rails, fencing and light structural supports exposed to the weather.

Round sections are preferred where members meet at varied angles, because the profile eliminates sharp corners that trap moisture and simplifies post-to-rail connections. Typical uses include staircase handrails, safety barriers, gate posts, greenhouse frames, conveyor supports and general pipe-rail runs. The 2.5 mm wall keeps the tube stiff enough for structural spans while remaining easy to cut, thread or weld with standard tools.
