Hybox cold formed and Celsius hot finished structural hollow sections (sometimes referred to as tubes), are manufactured in a range of circular, square, rectangular and elliptical shaped tubes. They are manufactured to standard grades in a range of sizes from 21.3 to 508mm, with wall thicknesses from 2 to 16mm. The full range of Tata Steel’s structural hollow sections are included in this EPD. Cold formed tubes are made from fully killed steel, which is critical to formability and weldability, and the dimensions and corner radii are controlled to tight tolerances. They are strong, light, cost-effective and aesthetically appealing structural steel hollow sections that provide reliable formability and toughness. They can be used in a wide range of structural and engineering applications, including those where specific properties and compliance with design codes are required, and are suitable for galvanising. Hot finished structural hollow sections are manufactured from normalised fine grain steel and combine high yield strength with lower carbon content for improved weldability and fabrication. Their applications include large-scale construction and building projects where the products strength and weldability is suitable for both internal and external structural use, including multi-storey columns, space frames, and lattice beams. The sections can also be used in the offshore industry for both primary and secondary applications, and for industrial and off-highway vehicles, such as cranes, excavators, bulldozers and dumper trucks.
