Cold rolled steel usually has a fine surface finish, tight size tolerance, and excellent machinability. Therefore, it is widely used in many applications, including manufacturing, construction, home appliances, automobiles, machinery, and so on. Below let us have a closer look at cold rolled steel uses together.
Cold rolled steel is a widely used material in the manufacturing industry. The very common cold rolled products made by it include:
1. Steel sheet — a thin, flat, and rectangular sheet of metal called cold rolled steel sheet.
2. Steel coil — a finished, thin, and flat steel sheet or strip which has been wound or coiled after cold rolling, namely cold rolled steel coil.
3. Tube — a steel piping with a hollow section and length that is much more than its diameter or circumference, known as cold rolled steel tube.
4. Substrate of painted steel — CR steel has good formability and paintability, making it the base metal of many painted steel products like galvanized steel, galvalume steel, SuperDyma steel, and PPGI steel.
In addition, other end products created by it include bars, strips, rods, and wires which are usually smaller than the same products available through hot rolling methods.
In the construction sector, cold rolled steel is commonly used for producing different steel structures such as columns, beams, joists, studs, floor decking, built-up sections, and other components. Such cold rolled steel uses have become more and more popular since its standardization in 1946.
In addition, it has been used in many different construction projects like bridges, storage racks, grain bins, railways, transmission towers, drainage facilities, roofing & wall systems, sheds, buildings, garages, etc.
It’s proven that cold rolling can be potentially strengthened up to 20% compared to hot rolling. At the same time, this process offers cold rolled steel high stamping performance, no aging, good mechanical property, and low yield strength. Thus, it can be cut, bent, punched, drilled, and formed with excellent results. Therefore, more and more mechanical production factories will choose to use this material nowadays.
Due to cold-rolled work, this steel presents a glossy, smooth, and sturdy surface. Also, it has a tighter tolerance, meaning CRS can be rolled thinner by up to 50%. This makes it have a lot of uses in home appliances and metal furniture. For it not only guarantees a longer service life but also provides a more aesthetic and visually appealing surface.
By far, the ordinary cold-rolled steel uses in this industry we can find include washing machines, dryers, office filing cabinets, school lockers, refrigerators, electric fans, microwave ovens, and so on.
Steel is an intrinsic part of the automobile sector, in which cold rolled steel performs better than hot rolled steel. This is because CR steel is relatively more finished, wear-resistant, and shockproof. Therefore, in this industry, it is predominantly used to manufacture bodies and load-bearing elements of cars and vehicles. Also, it can be used to fabricate electric motors, automotive seat parts, pressings, fuel tanks, etc.
The cold rolled steel uses are not limited to the above. It can also be applied in many other places. Here list some for your reference:
– Lighting/plumbing fixtures, conveyor systems, aerospace parts, firearm parts, packing materials, hardware accessories;
– Toolboxes, exhaust pipes, precision instruments, metal containers, lawnmowers, tables, chairs, water heaters, cans, etc.
Generally, cold rolled steel in different grades can be more suitable for one specific application. Here summarizes the common cold rolled steel products in different grades to show the points. Let’s see the table sheet below.
