Unlock hidden space without moving premises

Running out of room in your Portsmouth warehouse or unit? It's a common headache we hear about all the time. Before you start looking at the eye-watering costs of relocating or signing a new lease, take a look up. Most industrial units in the Portsmouth area have metres of unused vertical space just sitting there. At RA Steelworks Services LTD, we help you reclaim that 'dead air' by installing custom mezzanine floors that practically double your usable square footage. Whether you're a growing logistics firm near the International Port or a retail business needing more showroom floor, building up is almost always cheaper and less disruptive than moving out.

Bespoke steel mezzanine floor installation by RA Steelworks Services LTD
Why Choose RA Steelworks

Expert Mezzanine Floor Design & Fabrication

Maximise your industrial or commercial space with RA Steelworks. We provide fully certified, BS EN 1090-1 compliant mezzanine floors across Southampton, Berkshire, Surrey, and West Sussex. Our coded welders and expert fabricators ensure every structural platform is engineered for safety, durability, and seamless installation.

Structural safety that keeps you compliant

When you're putting a massive steel platform over your staff and stock, 'near enough' isn't good enough. That’s why we take compliance so seriously. We aren't just guys with a welder; we're UKAS-accredited to BS EN 1090-1 and approved for Execution Class 2 (EXC2) structural steelwork. This means every beam and column we fabricate in our workshop is CE-marked and meets the strict safety standards required by UK Building Regulations (Part A). When the building control officer comes to visit your Portsmouth site, you'll have all the paperwork ready to show that your new floor is as safe as the ground it stands on.

Floors designed for your specific loads

Not all mezzanine floors are created equal. Are you planning on setting up a lightweight office space, or do you need to store heavy engine parts for marine repairs? We'll sit down with you to figure out the exact load-bearing capacity you need, measured in kilonewtons per square metre (kN/m²). For a standard office, 3.5kN/m² usually does the trick, but for heavy industrial storage, we can engineer structures to handle 10kN/m² or more. We consider everything from Uniformly Distributed Loads (UDL) to how the point loads from the columns will affect your existing concrete slab. It’s this attention to detail that ensures your floor doesn't just look the part, but performs under pressure.

Professional installation with minimal downtime

We know you've got a business to run. The last thing you need is a construction crew turning your warehouse into a no-go zone for weeks. Because we handle everything from the initial CAD design to the final on-site welding, we keep the process tight and efficient. Our coded welders are experts at working in live environments, ensuring that the installation of your steel frame, moisture-resistant P6 chipboard decking, or steel chequer plate is done with as little fuss as possible. We can even integrate essential extras like pallet gates, cat ladders, and fire-rated column casings to make sure your new floor is fully functional from day one.

Local experts serving the Portsmouth area

Being based just down the road means we’re never far away when you need a site survey or a quick progress update. We serve the whole of Portsmouth, from the bustling industrial estates in Hilsea and Copnor down to the docklands. Because we're local, we understand the logistics of getting steel into tight city-centre sites or busy maritime environments. You won't be dealing with a faceless national firm; you'll be talking to a dedicated team of fabricators and welders who take pride in helping Portsmouth businesses grow.

FAQ

Frequently Asked Questions

Answers to common questions about our bespoke mezzanine floor design and structural steelwork services in Southampton, Berkshire, Surrey and West Sussex , Berkshire, Surrey, and West Sussex.

Why Work With RA Steelworks Services LTD?

+

Choosing a fabricator is about more than just finding the lowest price. It’s about making sure your building is safe and your paperwork is in order. We take pride in our reputation for precision and reliability.
We hold UKAS accreditation to BS EN 1090-1 and are approved for Execution Class 2 (EXC2) structural steelwork. This isn't just a badge; it means every beam we cut and every joint we weld has been through a strict quality process. It gives your architect and building control officer the confidence they need to sign off on your project. Our welders are fully coded, meaning they have the certified skills to handle even the most critical load-bearing tasks. We are local, fully insured, and we understand the demands of the South Coast construction and marine industries.

How can a structural steel mezzanine help my Southampton business grow?

+

A mezzanine floor is one of the fastest ways to achieve commercial space expansion without the cost of moving premises. By building upwards, you can double your floor space for extra storage, office cubicles, or retail displays. Our industrial mezzanine floors are built using high-grade structural steel, creating a permanent, load-bearing platform that fits perfectly into your existing warehouse or unit.

What are the regulations for installing warehouse flooring and mezzanines?

+

Because a mezzanine is a significant structural addition, it must comply with BS EN 1090-1 standards. As UKAS-accredited fabricators, we make sure that the steelwork is CE-marked and safe for its intended use. You will usually need building regulations approval to make sure the floor meets fire safety and weight-loading requirements. We can help guide you through this process during the design and installation phase.

How much weight can a retail or office mezzanine floor actually hold?

+

The capacity of your mezzanine depends on what you plan to use it for. An office mezzanine floor usually requires a lower load rating than a heavy-duty industrial mezzanine used for pallet storage or machinery. During the design stage, we calculate the necessary beam sizes and column placements to make sure your platform is rock solid and fits your specific needs.

How long does the installation of a structural steel mezzanine take?

+

We aim to keep disruption to your business at a minimum. Because we fabricate the steel in our Southampton workshop first, the actual on-site installation is often very quick. Depending on the size and complexity, many mezzanine floors can be erected in just a few days. We’ll give you a clear timeline before we start so you can plan your operations around the work.
