Who It's For

Who Benefits from RSJ Installation

Homeowners Seeking Improvement

Choosing RSJ installation is ideal for homeowners who desire a more open ground floor, creating a spacious and inviting living area. By installing a structural steel beam, we can safely remove walls that previously separated rooms, preserving the building's integrity. Our installations are executed precisely according to structural engineer specifications, which guarantees the result is both secure and aesthetically pleasing.

Clients Planning Extensions

When adding a new extension to an existing building, the structural challenges require a high level of skill that surpasses ordinary construction tasks. RSJ installation plays a crucial role in effectively joining the two structures, with the steel beam designed to support the load in both a technically effective and visually clean manner. We handle every aspect of this process, from individual propping that supports existing structures to the necessary building control notifications, and we ensure all surfaces are returned to their original state afterwards.

Landlords and Property Investors

For landlords developing HMO properties or investors looking to enhance layouts for increased rental income, RSJ installation provides a dependable and enduring structural option. Incorporating rolled steel joists into a building at strategic locations enables significant spatial adjustments without compromising structural performance. After managing complex projects for over 20 years, we execute each RSJ installation with the precision and responsibility that serious property investors expect.

Clearing Work Zones

Dust travels fast during demolition. Clear out every piece of furniture, curtain, and wall decoration from the adjoining ground rooms. When installing an RSJ in Corsham, we need an entirely clear path right from your front driveway through the hallways. Heavy steel beams cannot navigate tight corners if storage boxes block doorways or if bikes lean against the walls. Roll up carpets completely to save them from coarse grit. Cover remaining fixed woodwork with thick protective timber sheets.

Managing Hidden Pipework Runs

Walls hide live services. You should isolate any central heating pipes, radiator runs, and electrical cables running inside the partition before any masonry gets broken away. If an unexpected copper water line sits right where the bearing padstone must rest, the whole job halts while a plumber drains down the system. Turn off the main stopcock early in the morning so everyone stays safe on site. Check where your gas run travels under the subfloorboards near the knock-through zone.

Structural Challenges We Tackle Precisely

Opening Up Living Areas

When a wall is removed, preserving the structural integrity of the whole building must be done with utmost precision. RSJ installation is our method for achieving this perfection by adding rolled steel joists designed to carry the loads that the removed structure used to support. Each RSJ we install is tailored according to a structural engineer's calculations, confirming that the methods employed are safe, accurately sized, and positioned for long-term durability. We maintain temporary supports throughout to shield the property during steps of the work.

Connecting Extensions Seamlessly

Merging a new extension with an existing residence involves its unique structural requirements, making RSJ installation crucial for establishing a polished, enduring union between the old and the new. We oversee the entire process, handling the notifications to building control and completing all necessary finishing works once the steel is positioned. With more than 20 years of experience managing structural and finishing tasks as a single contractor, we ensure the transitions remain as visually harmonious as they are structurally sound. The outcome is a home that feels cohesive and thoughtfully constructed.

Step-by-Step RSJ Installation Process

  1. Structural Assessment

    We start by examining the structural engineer's calculations to identify the precise RSJ specification needed for your assignment, making sure every detail is carefully reviewed before we start.

  2. Temporary Propping Installation

    Before any load-bearing wall is altered, we install temporary supports to safely uphold the existing structure during the RSJ installation.

  3. Building Control Notification

    We manage all essential notifications to building control for you, ensuring that the RSJ installation adheres to current regulations and is properly documented from the beginning.

  4. Steel Supply and Installation

    Our skilled team supplies and installs the RSJ according to the exact specifications provided by the structural engineer, whether we are opening the ground floor or merging a new extension with the property.

  5. Making Good and Final Finish

    After the RSJ is firmly in place and all supportive props are removed, we restore all impacted areas to a clean and finished state, preparing the space for the next stage of your project.

Handling Domestic Pipework

Plumbing cannot pass through solid flanges. You must plan alternate drops for heating lines and soil stacks because drilling holes through structural webs often weakens the beam. Fitting an RSJ in Corsham requires rerouting old waste feeds into adjacent stud cavities or under timber joists before packing mortar sets hard beneath the metal plates.

Wiring Drops and Fireboards

Cables require strict separation from hot metal surfaces. Electricians should pull cables away from masonry pockets, keeping ring mains completely clear of points where the steel beam presses directly into bearing walls. Wrap the profile with specialist gypsum layers to maintain proper thermal resistance and fire deflection. Clip conduit tightly against timber noggins rather than resting loose wires across raw flanges.

Structural Steel, Done Right

RSJ installation is one of the most consequential decisions in any structural project, and at Mucha Construction Ltd it is approached with the precision that two decades of experience demands. Every RSJ is supplied and installed in strict accordance with a structural engineer's calculations, ensuring that load transfer is handled correctly from the outset. Temporary propping is maintained throughout the process, and building control notification is managed on your behalf as a matter of course.

Opening Up Your Space

When a ground floor needs to be opened up or an extension connected to the existing structure, an RSJ forms the backbone of that transformation. Mucha Construction Ltd has carried out this work across a wide range of residential projects, each one requiring a considered approach to sequencing, propping, and structural integrity. The result is a clean, confident opening that performs exactly as the engineer intended, finished and made good to the highest standard.

One Contractor, Full Accountability

What sets Mucha Construction Ltd apart is the ability to deliver RSJ installation as part of a fully coordinated project rather than an isolated trade visit. From the initial structural assessment through to plastering, decoration, and final handover, every stage is managed under a single contractor. This continuity eliminates the coordination gaps that so often compromise quality, ensuring that the RSJ and every element surrounding it is completed with the same level of care and craftsmanship.
