With the growth of steel as a readily available construction material, we should look at how the two methods used to manufacture steel, hot rolling versus cold rolling, are different from one another as building tools.
How can we define the two types of steel manufacturing?
Hot rolling of steel is when the temperature is of the steel is heated up to 1000 Centigrade, and incorporating a process that prevents the steel from properly hardening while it is being worked on. As the steel cools down to room temperature it will alter.
Cold rolling of steel means that the entire process is done at room temperature so that there is no need for a cool down. This ensures that the tolerance of the steel is unaltered and that is more durable and more difficult to break than its hot-rolled counterpart. This technique was first discovered during World War One, and although this method has been around for over a century it has only really count on in the construction world over the last twenty years. Cold rolling steel is more versatile and the more versatile your products for building are the better off your project is going to go.
What kind of projects is hot rolled steel used for and what kind of projects is cold rolled steel used for?
To put it simply, the larger a building is, the more likely it is to be built with hot steel. This is especially true when the building is being used to store large materials or when cranes or other forms of heavy equipment need to be attached to the growing framework. The main reason behind this process is that hot-rolled steel is actually thicker and more robust than the cold rolling counterpart. Hot rolled steel is also being used to construct portal frame steel buildings.
In today’s world of construction, lighter materials are preferred because it makes the building process much easier and requires less heavy machinery to get the project done. This gives the cold rolled steel an advantage as we continue to learn more about what steel created in this method is capable of. Cold rolled steel has a much better strength to weight ratio and is much easier to handle for construction staff. The cold rolled steel is much more suited for smaller buildings, often in the size span of 22 meters and a height of six and a half meters. These buildings are often shallower and much more cost effective.
The larger a building is and the more storage you need you should seek out the hot rolled steel. It’s heavier and can withstand heavy machinery helping to put it all together. If your building is smaller and you are looking for a much more cost-effective way to build a sturdier building on a budget, you should seek out the cold rolled steel.
