We''re often asked about the differences between hot rolled steel and cold rolled steel. Here''s what you need to know! All of ours UB, UC, PFC, RSA, flats are hot rolled whereas SHS, CHS, RHS that we provide are cold rolled structural steel.
Cold rolled steel is stored and sold in coiled form after rolling. Steel comes in many grades, specifications, shapes, and finishes—the World Steel Association lists over 3,500 different grades of steel, each with unique properties. The various types mean that steel can by widely used in infrastructure, appliances, vehicles, wind turbines, and many more applications.
One important difference to understand is hot rolled steel and cold rolled steel. This lack of knowledge concerning the two types of steel is more common than you would think. The difference is not in their specifications or grade, but in how they are processed at a mill.
Hot rolled and cold rolled are the process of steel plate or profile forming. They have a great influence on the structure and performance of steel.. The rolling of steel is mainly hot rolling, and cold rolling is usually used only for the production of steel with precise sizes such as .
Hot Rolled Sheet Steel is an unprocessed, mill edge coiled product and does not include any processing such as temper rolling, tension leveling, pickling, oiling or side trimming. Hot Rolled products are produced to ASTM Specifications A1011, A659, A635 or A1018.

A series of shaping operations, which include sizing, breakdown, semiroughing, semifinishing, roughing and finishing are required to create cold rolled shapes. Finished products created by the cold rolled steel process include bars, strips, rods and sheets which are usually smaller than the same products available through hot rolled methods.
Cold rolled sheet steel is produced from hot rolled sheet with additional processing steps such as pickling, cold reduction, annealing and temper rolling. 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.

Jul 16, 2014· Cold rolled is the next step along the line of flatrolled steel products. The process starts with hot rolled PO. Hot rolled is processed to a final thickness that is heavier than most sheet products. A coldreducing process is used, which results in a thinner thickness. The cold reduction starts with tension to the sheet.

Cold Rolled Steel is a mill product made with a high degree of gauge accuracy and uniformity of physical characteristics. The smooth deoxidized matte finish gives an excellent base for paint, lacquer and enamel. Box annealing and absence of scale permit stamping and moderate drawing operations.
Cold rolled steel is much more preferred in the machining world where the quality of the steel is an important factor of the quality of the final product, and the appearance of the steel is also an important factor. Summary. The following are some of the key differences in hot rolled vs cold rolled steel:
Hot Rolled Steel vs. Cold Rolled Steel. The difference between hot rolled and cold rolled steel is this recrystallization point. Cold rolling is done when the metal is able to form "new grains" as the old ones are deformed by rolling and bending the metal.
Cold Rolled Steels can be joined using accepted welding practices. SURFACE FINISH Cold Rolled Steels are manufactured with a matte finish obtained by rolling with specially roughened rolls on the cold mill and the temper mill. This finish helps to maintain effective lubrication during metal forming and improves the appearance of painted surfaces.
Steel Forming Process 2 – Cold Rolled Steel. Cold rolling is a metal working process in which metal is deformed by passing it through rollers at a temperature below its recrystallization temperature. Cold rolling increases the yield strength and hardness of a metal .
