From its small beginnings in 1911, BILSTEIN has grown to be one of the most important coldrolled steel strip producers in the world. The success story of our familyowned company was made possible first and foremost by the tireless efforts and .
Cold Rolled Steel Strip is produced, as the term suggests by the further rolling of strip produced by the hot strip mills. Prior to cold rolling, the mill scale has to be removed, normally by the Pickling Process which uses mechanical manipulation (around small diameter rolls) and acid to dissolve the surface scale.
Rerolled aluminum coil available in a wide range of precise thickness and width capabilities for consistent and tight gauge tolerances. Cold Rolled Aluminum Strip | .
The feed stock of cold strip mills are coils rolled by hot strip mills. If abnormal conditions, such as excessive roll wear, occur in the hot strip mill, thickness profile ridges are produced on the hot rolled strip. When the hot rolled strip with ridges is subsequently fed into a cold mill, local buckles are produced in the cold rolled strip.
The thickness of the hotrolled strip is important in that the properties of the final cold rolled and annealed product is influenced by the percent of cold reduction. This means that the thickness of each hotrolled coil is carefully controlled to provide the mill with a specific thickness to achieve the proper percent cold reduction.
The output from a strip mill is coiled and, subsequently, used as the feed for a cold rolling mill or used directly by fabricators. Billets, for rerolling, are subsequently rolled in either a merchant, bar or rod mill. Merchant or bar mills produce a variety of shaped products such as angles, channels, beams, rounds (long or coiled) and hexagons.
A stateoftheart coldrolling mill is a prerequisite for the production of steel strip that satisfies the tightest tolerance demands at high productivity levels – for carbon, stainless and special steel grades such as SS (advanced highstrength steel).

Farwest is proud to carry an A57250 flatroll inventory ranging from 3/16″ to 1/2″ thick in widths of 48″ to 96″ wide. Standard lengths of 96″, 120″, 144″, and 240″ are inventoried for many stocking sizes, and can also be sourced or processed to any desired length.
The result is that when hotrolled steel cools, it shrinks slightly, so there is less control of the final size and shape of the finished product, compared to coldrolled steel. Creating strip steel necessitates further processing in cold reduction mills, where the material is cooled at room temperature followed by annealing and/or tempers rolling.
Our precisely designated Copper Strip 4 Hi Cold Rolling Mill is ideally utilized for thinning the piece of copper to develop strip. These rolling mills are developed by making use of premium grade materials and sophisticated technologies to ensure proper rolling of copper strips.
A fullyprocessed strip is also made with a clean, uniform finish. Annealed And OnePass Hot Rolled Strip Hot rolled strip is annealed for softness and gaugecorrected for closer thickness tolerances on a cold rolling mill. This is a lower cost option where the degree of spheroidization, dimensional tolerances or surface finish may not be as ...
If all measures in the hot strip mills fail and ridges are produced on the hot band, flattening the ridges before cold rolling using a mill stand with very high local rigidity (Liu et al., 2011b, 2012) Liu et al., 2011b Liu et al., 2012 can be used to reduce the local buckles significantly. The uniformity of the metallurgyrelated factors in ...

Cold rolled steel is a product that has been cold reduced, as opposed to hot rolled, in order to impart specific mechanical properties, surface finish, gauge tolerance and strip shape. The benefits of cold rolled sheet include excellent performance in applications that require deep drawing and intricate bending and forming.
