What is an RSJ?
Non-load bearing and load bearing walls are built when a house is built. The distinction is that load-bearing walls support the whole building’s structural weight, while walls that are not load-bearing serve to create a separation between rooms.
If you’re planning to build an open-plan living space by taking out or modifying a wall bearing load it is necessary to install a steel RSJ beam to support the load, or else your home could fall due to the fact that it’s not equipped with the proper support.
Installing correctly an RSJ requires meticulous calculations, time and expertise. A skilled builder or structural engineer should examine the site and conduct steel beam calculations to figure out the type of wall they’ll be dealing with as well as the length of beam that they’ll require as well as the weight that the beam can handle.
The correct installation of the correct RSJ requires precise calculations, patience, and expertise. An experienced structural engineer must examine the site and conduct steel beam calculations to figure out what kind of wall that they’ll need to construct as well as the length of the beam that they’ll require and how much weight the beam will support.
This affects the cost you pay for an RSJ installed at home.
Breakdown of The Costs
Steel supports, like universal beams, are frequently employed in construction. They’re strong, easy to construct and affordable to set up. They’re available in various standard lengths that can be used for almost every need.
But, length isn’t all the thing to take into consideration. When the length grows,
RSJ calculations are also utilized by mechanical engineers to expand the dimensions of the cross-sectional profiles. That means that as the RSJ gets in length, it will not be bent more than limits of safety allow.
This means that the cost of steel “I Beam” increases when its length and profile increase. Additionally, the higher the amount of steel that is used for the production of an universal beam, the heavier it gets.
If it’s a heavy object, it’ll be harder to lift, and may require the use of lifting machines. This means that labour costs will increase, as does the price associated with an RSJ installation also increases.
The price of installing an RSJ is contingent on the size of the beam, the size of your location, the need for utilities to be relocated and the location you reside in within the United Kingdom. A RSJ installation is typically priced between £1500 to £2500.
This covers the cost of hiring an engineer to design the structure as well as skip hire, plastering Building Control approval fees, construction materials and labour for installation.

Because of this, we will go over the procedure and the timelines of putting in an RSJ.
If a wall has to be removed prior to the installation of an RSJ It is best done by a professional. It is not something that can be done by hand. The process of removal is easy when done with care and steadily; however, safety must always be the first priority, and preparation is essential to avoid injury or damage.
A structural engineer must be consulted personally by the engineer, who will come to the site of work to assess the structure and offer relevant calculations and recommendations. This is a crucial step and you should schedule a time to complete it and then review the data provided.
A load-bearing wall could be removed in one day by a group consisting of two or three people in accordance with how big the building is. The removal process must be carried out in a safe and sensible manner by collecting rubble when it has been formed from the wall being destroyed.
This helps reduce the amount of waste to manage and makes the workplace more secure and evident.
If there are enough people available to do it securely and safely, putting up the RSJ beam will take about one or two hours. Padstones are put into the holes in which the RSJ will be placed to support it and elevate it up to the right level to support the ceiling the joists the weight.
The steel RSJ must be guided to its place by a team consisting of two to four people. It’s crucial to move the beam as close to its final position as you can before putting in the prop supports made of steel below the ceiling as they can block access to the site of installation once they’re erected.
This issue may be an expensive error, not just in terms of labour costs however also time. It can help finish the job efficiently, in a practical and safe way when everyone in the group understands the procedure to set up the RSJ and discusses things prior to lifting any object.
There must be either an electrician or plumber to take down and secure the pipes and wires which are being taken off the wall.
If the existence of any live service was not previously detected and there was no arrangement for the necessary tradesperson to be present to handle it, this could cause delays in the installation. Then you may have to be patient for the tradesperson to be available.
So, taking down the wall and putting up the RSJ will take between one and two days, based on the dimensions of the wall. Plan for four to eight hours for the plastering process depending on how large the space which requires plastering, and one day for painting or decorating, based on what size the space that requires painting or decorating.
This means that after waiting for the engineers and other tradespeople installing an RSJ and completing the work could take as long as an entire week.
|Installing RSJ||1-2 Hours|
|Removing a Wall||1-2 Days|
|Re-Decorating||Half a Day|
Types of RSJ
To be used in construction of steel, RSJs come in a range of sizes and shapes.

- It could be more expensive.
Benefits of RSJ Installation
The advantages from RSJ (rolled steel joint) beams are not fading away. These beams have been utilized for a number of purposes over the decades due to their tremendous strength and support as well as their quality.
They are commonly used in commercial and industrial construction, and are increasing in popularity for home-based projects such as new floors, patios and decks. Since the material can be easily bent and handled it’s a versatile choice.
Steel is widely known for its eco-friendly qualities. Steel is used in many construction projects due to the fact that the building sector has improved its environmental reputation in recent years.
The amount of instances RSJ beams could be recycled is limitless, which means less waste will be sent to landfills.
Steel is also thought of as an environmentally friendly option since it doesn’t emit greenhouse gases. When compared to alternatives such as wood or concrete, RSJ steel beams are very cost-effective.
Steel has the strongest strength-to-weight ratio out of all building materials, and is able to withstand massive amounts of strain and weight. It is able to withstand almost anything the weather throws at it, and that is why it is often utilized in regions in which the weather is especially difficult.
Create, shape, bend or bend RSJ beams to a range of lengths and dimensions. They’re also fire-resistant, and don’t require any chemical treatments. Steel that’s been galvanised is not likely to be rusty. It is able to prevent structures from falling in earthquakes or hurricanes.
The steel beams, as stated, are custom-designed according to your requirements. Due to the material’s versatility it is possible to design. Steel can be cut and measured to any size and shape.
The best part is that moulding does not alter the quality of the material. Additionally, because of its flexibility, it’s more secure to use as it can be reused easily.
Gives a Sleek Finish
Although the appearance of knotty, unfinished wood might be appealing in certain designs that are rustic, steel is a sleek alternative. It is different from other materials like wood, and is constructed therefore it will be smooth and free from the imperfections and knots that are characteristic of wood.
How Much Does It Cost to Remove an RSJ?
If you’re building a new support wall or tearing down the wall that is above the beam made of steel it is possible to get rid of an RSJ. Another reason for removing one RSJ can be replacing it with a different kind of support beam or substituting it with another RSJ.
Removal of the RSJ is a challenging job that must be performed with care and correctly. If you’re unsure of the requirements for removal of an RSJ You should speak with an engineer in structural engineering for guidance on the most effective method of taking off the joists that roll.
