The Cost Of Installing An RSJ Support Beam

Find out the costing involved with installing an RSJ support beam. We’ll discuss and cover the cost for different steel beam prices, along with the different sizes and the costs for hiring a builder for installation. See the different types of RSJ’s and when it’s time to use one.

What is an RSJ and what are they used for?

RSJ stands for Rolled Steel Joist. The purpose of an RSJ support beam is used for structural steelwork. They’re shaped like I or H letters. Which can also be their names as some people refer them by. The “I beam” is the most common type. Learn below the many types of RSJ support beams.

Ultimately, an RSJ is the support beam for supporting the weight of a ceiling. In most cases, they’re used for taking out a supporting wall and replacing with an RSJ in its place to hold. However they’re used as structural support for many different constructions. The most common use is for a load-bearing wall.

Load-bearing wall

Supports the weight of a roof structure or floor. It’s called a load-bearing wall because they bear a load. A non load-bearing wall, which is sometimes called a partition wall, is dependent only on holding up itself.

Check with a structural engineer to determine whether a wall is load-bearing or not. You can do some simple checks and tap the wall to see if you can hear a hollow sound. Though, this may not be the final answer in finding out if it’s load-bearing or not. If the wall runs at a 90-degree angle to the joists, then it’s said to be a good chance that it is load-bearing.

Situations when needing an RSJ

An RSJ is useful for those projects that need a wall replacing or for general support for structural steelwork. You could help save the house in the long run by upping the home value by adding in extensions or alternating a room for the good.

For example, if you’re trying to do an extension in the home or you’re trying to make one room bigger than it originally was, an RSJ installation will be worth it. You can then add in decorating trends or display features for the extra space.

The most common feature of including an RSJ is by extending the kitchen through to the dining room. It provides a much bigger space to roam around in the room and provides a relaxing dining experience.

Of course all homes are different in layout so you may be limited to what you can do. But be creative and get yourself an extension for your home. It may be the turning point in increasing the home’s value.

Installing an RSJ – The only way would be to go through a structural engineer or a building company to ensure everything is done right and pay for the installation.

For DIY devotees wanting to limit down on spend. Unfortunately this isn’t achievable to do so on your own. There’s a lot of things to consider when installing an RSJ.

You will need the calculation required from a skilled structural engineer before proceeding and approval from the building control. Plus, you will need a building approval certificate which is essential.

A structural engineer will calculate the correct load which is needed for the support, and will then pass this information onto a skilled builder, who will then liaise closely with a steel fabricator to manufacture the RSJ to suit the correct fit. This will all then be signed off, delivered, and made ready for project structural work.

General sizing of the RSJ and the type of beam can be correctly measured by a structural engineer using the length of the beam, and the details of the load it has to bear.

This type of work without professional help can risk the element of the house.

Planning permission to install an RSJ – Rules and regulations change from time to time, so it’s important to check with the planning department before any RSJ installations are taking place.
