Steel plates are made from steel slab or ingots. Steel plate is a type of flat-rolled product and is thicker than steel sheet. It can be sold in discrete pieces as well in a coiled form.
Reversing mill plate
Reversing mill plate is produced from slab on a reversing mill. The slab is passed through back and forth through the mill to achieve the desired thickness. Reversing mill plate is also called quarto plate.
Reversing mill plate are usually over 5 metres (5,000 mm) in width and between 5mm and 400 mm thickness. There are thicker plates in the market for very niche applications.
Reversing mill plate can go up to 35 meters long and can weigh 35 tonnes or above
Reversing mill plates are used in various end-user sectors such as building and construction, engineering, line pipes, offshore installation, shipbuilding, transport and windfarms
Coil plate can be available in carbon, alloy and stainless grades with a variety of thickness and chemistry depending on applications.
Most plates are available in the thickness range of 5-80 mm and can overlaps with hot rolled coil (HRC) at the lower end of thickness. The coiled plate is commonly less than 2 meter in width and around 12-14 mm in thickness. Coil plate is rolled on multiple stands, which is called a tandem mill. It is rolled continuously without reversing the direction. It is also called a continuously produced plate (CPP).
Coil plates are used in various applications such s building and construction, engineering, energy pipes, offshore installations, shipbuilding, automotive and wind farms.
