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.
Use hot rolled steel if very precise shapes and tolerances are not required, for example on railroad tracks or many parts used in the construction and welding industries. Cold rolled steel can be formed in more precise shapes with precise tolerances and is perfect for moving parts, such as axles and automotive parts. Hot and Cold Rolling in Mexico
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 rolling cannot reduce the thickness of a workpiece as much as hot rolling in a single pass. Coldrolled sheets and strips come in various conditions: fullhard, halfhard, quarterhard, and skinrolled. Fullhard rolling reduces the thickness by 50%, while the others involve less of a reduction.
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.
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.

COLDROLLED STEEL. As you might suspect, the manufacturing process behind coldrolled steel is a bit different. Despite the name, this process refers to steel that is pressed with the pressure of a roller at room temperature. Compared to hotrolled steel, coldrolled steel has a nearly 20% increase in strength through the use of strain hardening.
Dimensionally, the differences between a hot mill product and a cold rolled product are as follows: The outside corners of a hot mill product will usually be square corners, whereas the cold roll formed product will have radius corners which are a product of the inside radius (usually 1T or greater) plus material thickness and stretch.
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.
