G.I. Round Tube

Round tubes are cylindrical in shape that are hollow inside. These are measured by their outside diameter, unlike pipes which are measured by their inside diameter. Round tubes are applied in various structural and architectural projects such as steel frames for gate construction, railings, and automotive parts.

It is available in 2 variants – black iron (B.I.) and galvanized iron (G.I.). Galvanized Iron is covered with zinc to make steel resistant to rust. Black Iron is uncoated and the black color is from the iron oxide made on its surface throughout the manufacturing process.
