Steel, this thing, is something that we see a lot in daily life, but ordinary people don’t know much about it. There are several types of steel, the most important of which are hot rolled steel and cold rolled steel. This is easy to say, but it takes time to understand the difference between the two.
Hot rolled steel, also called hot rolled steel, is actually steel that has been put into high temperature to be “scalded”. When the steel is hot, it is sent to those big rollers to be pressed back and forth. In this way, the steel plate becomes thinner and smooth like a big pancake. This hot rolled steel is not so delicate in shape, but it is strong and suitable for making large pieces of iron sheets, such as large objects such as cars and beams.

The other is cold rolled steel. Cold rolled steel, at first glance, is similar to hot rolled steel, but it is hot rolled steel that is sent to a cold place to be pressed. After cold pressing, the steel becomes smoother and harder, and more suitable for delicate work, such as furniture and decoration. Therefore, cold rolled steel is often used for things that are beautiful and durable.
Hot rolled steel: The rolled steel is rough and not very smooth, but it is cheap and suitable for large projects.
Cold rolled steel: After cold pressing, it is hard and smooth, and it is perfect for small things.
Besides, there are many ways to press steel. For example, roll forming and roll bending are actually a long steel strip that is thrown into a machine and pressed over and over again to form the desired shape. Most of them are rolled into pipes, columns or plates, which are used in construction and can also be used to make machine parts.
Besides, there are many types of steel rolls on the market, and sheet metal rolls are a large category. You can choose any size you want. Thick steel rolls are pressed to make strong and large things, such as industrial parts; thin steel rolls are suitable for making small parts or decorative things, and they are all ready-made. Steel coils can also be made into various finished products. If you make cold rolled steel, you can also polish it to make the surface smoother.
The process used looks complicated, but in fact it is nothing more than sending the steel strip back and forth into the roller. If it is thick, it will be pressed thinner, and if it is rolled rounder, it will become a roll. No matter what equipment it is, pressing the steel back and forth is always to make it obedient and easy to use.
These rolls of steel are actually very useful in the market. Whether it is a house, a car, or some machine parts, everything is indispensable. Hot rolled steel and cold rolled steel have their own abilities. Hot rolled steel is thick but not delicate, while cold rolled steel is delicate and strong. So, if you have a headache looking at these steel rolls, it means you haven’t found their good uses!
Besides, it’s not difficult to buy steel rolls. If you are doing big projects or building houses, hot rolled steel is definitely right; if you want to make some furniture and detailed decorations, then cold rolled steel is suitable. But you still have to find out before you choose, after all, we are not experts, and buying the right one is the best.
