What is hot rolled steel sheet? It is steel. This steel is heated in the furnace to a very high temperature of about 1700 degrees. At that time, the steel becomes soft. Just like a hammer for forging iron, it is pressed flat and turned into sheets of iron sheets, which saves trouble. Why is the temperature so high? Because the temperature is high, the steel becomes soft and it is easier to shape! This is what people call “hot rolled” steel sheet.
What do you think is the use of hot rolled steel sheet? Let’s take an example. If you build a house or a shed, this kind of steel sheet will come in handy. Its surface is a little rougher than cold rolled steel, not very smooth, but it doesn’t matter. It’s practical. We are also particular about this practicality!
What is the difference between hot rolling and cold rolling?
Actually, the two types of steel are made at different temperatures. Hot rolling means that the steel is burned very hot and then pressed into sheets; cold rolling means that it is first hot rolled and then cooled, and then processed to make it smoother and more accurate in size. Cold-rolled steel plates are mostly used for fine work. For example, some of the beautiful buildings built in the city use cold-rolled steel plates. But hot-rolled steel plates are stronger and more durable. We can use them to build sheds and bridges!
What are the benefits of hot-rolled steel plates?
This thing is not expensive and is especially suitable for large projects. If you have a larger building at home, such as a shed or foundation, you can use it. It can also be welded and punched at will. This thing is very convenient to use! In some places, it is also coated with zinc to prevent rust! So, it is not afraid of wind and sun in some outdoor projects and is not easy to rust. Wear-resistant, impact-resistant, etc., we often use it when we build roads and bridges.
Hot-rolled steel plates are cheap and suitable for large projects.
They can be welded and punched, making them convenient to work with.
Add a galvanized layer, which is durable and rust-resistant.
There are so many uses for hot-rolled steel plates! For example, building railways, building factories, and making bridges are all inseparable from it. You can imagine that it is wear-resistant and not afraid of bumps. We have to use it to make farm tools. And those large machine parts, car chassis, etc., they also use this kind of hot-rolled steel.
So why do people still use cold-rolled ones?
Well, although cold-rolled steel is more expensive, it is fine and can be used for work that requires accurate dimensions and smooth surfaces. But for work that is durable and can withstand impact, hot-rolled steel is more suitable. Look at this hot-rolled steel, it is solid, wear-resistant and durable, especially for building houses, it can be used in any way!
So, hot-rolled steel plates are just like this, cheap and practical, and can be used for any work. Whether it is building houses, roads or machine parts, it can be used in a big way! If you are planning to do a big project, hot-rolled steel plates can definitely help you!
