Process of galvanizing. Today the corrugation process is carried out using the process of roll forming. The galvannealing line is usually equipped with a skin pass mill, a tension leveler, and chemical treatment equipment for chromating, following the galvannealing furnace.
Rolling mill equipment, components assemblies include hot leveler cassette assemblies, uncoilers, roller tables, entry shears, feed roll assemblies, pinch roll assemblies, and cooling beds for hot strip rolling mills, skinpass mills, and tandem mills.
Skin pass mills, which are also often referred to as temper mills, can be single or 2stand units and have a 2high or 4high mill roll configuration. Mills with a 2stand configuration are usually considered preferable when processing harder materials.
