Expert Steel Beams Rsj in Brading, Isle of Wight

RSJ stands for Rolled Steel Joist, though you might hear people call them steel beams or "I-beams." They are the heavy-duty supports that keep your building safe when you make structural changes. If you are planning an open-plan living area or a kitchen extension in Southampton, an RSJ is usually what holds up the floor or roof above once a wall is taken out. We cut these to your exact measurements in our workshop so they fit perfectly the first time.

It comes down to safety and the law. All structural steel used in the UK must be CE-marked and fabricated by a company with BS EN 1090-1 accreditation. RA Steelworks holds this certification, which means our materials and our welding processes are checked by independent auditors. Your local building control officer in Southampton will likely ask for these certificates. Using a certified supplier means your project meets building regulations and your home stays structurally sound.

While they both look like steel girders, they do different jobs. A Universal Beam (UB) has a tall, narrow profile that makes it great for horizontal spans, like across a wide doorway. A Universal Column (UC) is wider and more square, designed to carry heavy vertical loads in a smaller space. You don't need to guess which one you need—your structural engineer will specify the exact type and size on your plans, and we will fabricate it to those details in our Southampton workshop.

We offer a full service that goes beyond just being an RSJ supplier. Our team can manage the fabrication, including any drilling or plate welding required, and then help with the on-site work. Because we have coded welders on hand, we can handle complex connections on-site that a standard builder might not be equipped for. We work across Southampton and the wider Hampshire area to make the process as smooth as possible for your construction team.

Not every project fits a standard mould. If your Southampton build requires bespoke brackets, cranked beams, or intricate steel frames, we can help. We work with mild steel, stainless steel, and aluminium to create custom solutions that standard suppliers often cannot offer. From decorative metalwork to complex structural frames, we have the tools and the expertise to build exactly what your design requires.

We are fully equipped for larger projects. While we do a lot of residential steelwork, we also provide structural steel for warehouses, mezzanine floors, and industrial units across Southampton and the South Coast. Our Execution Class 2 (EXC2) rating means we are certified to work on a wide range of commercial structures, giving you the same high standards of safety and compliance that we bring to our home extension projects.

Based right here in Southampton, RA Steelworks Services LTD is ideally placed to serve the local area. We cover the city centre, the New Forest, Winchester, and all across Hampshire and Dorset. Being local means we can often offer better delivery times and a more personal service than national suppliers. You can speak directly to the people fabricating your steel if you have questions about the technical details of your order.
