, external structural applications as well as in certain packaging applications, such as food containers. Plates. Plates are produced by hot-rolling either reheated slabs or ingots. The principal end uses for plates include various structural products such as for bridge construction, storage vessels, tanks, shipbuilding, line pipe, industrial machinery and equipment. Tinplate . Tinplate is a light-gauge, cold-rolled, low-carbon steel usually coated with a micro-thin layer of tin. Tinplate is usually between 0.14 millimeters and 0.84 millimeters thick and offers particular advantages for packaging, such as strength, workability, corrosion resistance, weldability and ease in decoration. Food and general line steel containers are made from tinplate. Electrical steels. There are two principal types of electrical steel: non-grain oriented fully processed steels and non-grain oriented semi-processed steels. Non-grain oriented fully processed steels are iron-silicon alloys with varying silicon contents and have similar magnetic properties in all directions in the plane of the sheet. They are principally used for motors, generators, alternators, ballasts, small transformers and a variety of other electromagnetic applications. A wide range of products, including a newly developed thin gauge material for high frequency applications, are available. Non-grain oriented semi- processed steels are largely non-silicon alloys sold in the not finally annealed condition to enhance punchability. Low power loss and good permeability properties are developed after final annealing of the laminations.

Long products Billets/Blooms. Billets and blooms are semi-finished steel products. Billets generally have square cross-sections up to 180 millimeters by 180 millimeters, and blooms generally have square or rectangular cross-sections greater than 180 millimeters by 180 millimeters. These products are either continuously cast or rolled from ingots and are used for further processing by rolling to produce finished products like bars, wire rod and sections. Bars. Bars are long steel products that are rolled from billets. Merchant bar and reinforcing bar (rebar) are two common categories of bars. Merchant bars include rounds, flats, angles, squares, and channels that are used by fabricators to manufacture a wide variety of products such as furniture, stair railings, and farm equipment. Rebar is used to strengthen concrete in highways, bridges and buildings. Special bar quality (“SBQ”) steel . SBQ steel is the highest quality steel long product and is
