If you are in charge of selecting building materials for a new building, you have a decision to make when it comes to selecting steel poles and support beams. You can select beams and poles that are made from hot rolled steel or cold rolled steel. There are pros and cons to both types of materials and learning about these pros and cons can help you make a decision that makes the most sense for the building you are in charge of constructing. Here are some of the pros and cons to cold rolled steel.
Cons of Cold Rolled Steel
If you are looking into using cold rolled steel on your project, you will have to take the price of the steel into consideration. One of the downsides to using cold rolled steel over hot rolled steel is the higher price of steel that is cold rolled.
Hot rolled steel is easier to work with and manipulate. This is because the steel is heated up to such a level that it easily bends, rolls and can be cut. This makes the process faster and thus, helps to keep expenses low. On the other hand, cold rolled steel is harder to work with and manipulate. This means it takes more time to shape and form, which in turn, drives the cost up.
If you have a tight budget you are working with, cold rolled steel may not fit into the budget. However, if you have a healthy building budget, cold rolled steel may be something that you want to consider.
- Inability to Change the Width of the Steel
Due to the high temperatures, you can easily shave down a metal sheet when using a hot rolling technique. This allows a metal fabricator to change the width of the steel sheet, beam or pole they are working with as they fabricate the metal. However, this can't be done when cold rolling because the temperatures aren't hot enough to liquefy the metal and shave it down.
A disadvantage to cold rolled steel is that you don't have the ability to change the width of the steel that you are working with. As such, when the cold rolling technique is being utilized, it is important to use the appropriate width of steel sheets. Unfortunately, if a warehouse doesn't have those in stock, they have to wait to get them in, which can delay the construction of your building. Or, if you need a unique or abnormal steel thickness, you may not be able to go with cold rolling.
Pros of Cold Rolled Steel
One of the major advantages to cold rolling steel is that the steel is up to 20 percent stronger when compared to heat rolled steel. This is because using heat to roll steel weakens the steel. When you don't subject the steel to hot temperatures, it keeps its structural integrity, which can make it stronger.
While cold rolled steel may cost a little bit more, you get a building that is stronger, which can help your beams and structural supports last longer and support more weight. This peace of mind may be well worth the additional cost.
- Has a More Desirable Surface Finish
The other benefit to cold rolled steel is that it has a more desirable surface finish. Cold rolled steel looks better than heat rolled steel. This is one of the main reasons why cold rolled steel is the preferred technique for steel that is used in furniture, cars and exterior home finishes.
While the finish of your steel poles and beams may not make a huge difference to you if you are hiding the beams and support posts, it should be a consideration if you are leaving any beams or posts exposed. Cold rolled steel has a clean, modern look, whereas hot rolled steel can look unfinished, jagged and worn.
Deciding between cold rolled and hot rolled steel is a big decision. However, taking the time to learn about these two building materials can help you decide which is the better product for your construction project.
