Heavy or structural sections are steel products such as beams or columns which are usually formed with a specific cross section shape e.g. H, I or U. Used to build large structures such as multi-storey buildings and bridges.
Hot rolled from steel billet, wire rod is delivered as coil, most commonly at 5.5mm dia. Close control of final cooling is a critical part of production. The most important characteristic for determining a rod's end use is its drawability.
Seamless tubes are made by rolling a preheated billet between offset rolls to create a tube shell. The tube shell is then elongated in a multi-stand rolling mill to achieve the desired wall thickness and a limited range of diameters.
