What is a Hollow Section?
A hollow structural section (HSS) is a type of metal profile with a hollow cross-section. The term is used predominantly in the United States, or other countries which follow US construction or engineering terminology.
While solid steel beams have their place in construction projects, you can also use hollow section products. These beams can be circular, square, or rectangular. They look like any other beam from the outside; however, as compared to other solid beams, the inside is hollow. Learn more at hollow section malaysia.
What are the Key Benefits of Hollow Section Structural Steel Beams?
1. Get to Know Lightweight Strength
While standard steel beams might seem stronger than hollow beams because they are solid, this isn’t always the case. Hollow sectional beams sometimes can outperform solid products. For instance, you usually get better protection against the crooked movement in a hollow section beam. The materials in the beam are more equally distributed around its axis. So, the probability of the beam moving, bending, or deforming is less likely if it is subjected to movement on the ground or from high winds.
Furthermore, fully solid beams are also heavy. Their weight might restrict certain design plans. When this happens, you might have to spend more time and money creating the right supporting foundation and structure for your planned structure to build. This isn’t a problem if you use hollow products. They aren’t solid, so they don’t weigh as much or put as much pressure on the ground. This way, you can get a better strength-to-weight ratio.
2. Lower Your Project Costs
You are likely to see cost savings if you use some hollow structural steel beams in your project. To illustrate, your initial purchasing costs could be lower. Hollow beams use less steel when they are manufactured than solid products because they have an unfilled core. Your beam costs could be lower if you use less steel.
The lightweight strength of these beams also has cost benefits. Hollow beams are often light and strong enough to span greater distances than solid products. You might be able to reduce the number of beams used to build supports and structures. Hence, it proves that the fewer beams you have to buy, the lower your costs will be.
3. Take Advantage of the Interior Space
Some might not think that the inside of a hollow section beam is of any use. But, this space can actually improve a build. There are times when parts of a ventilation or heating system inside beams can be placed. Or, the beams can be filled with concrete to ensure their usability. For example, if you fill the hollows of a beam, then you boost its bearing capabilities. This is useful if you want to use narrow beams but need to give them extra support. Or, you can use internal concrete to make beams more fire-resistant.
