LSGF is fabricated using cold rolled steel and assembled offsite as per design specifications to provide a complete framework solution for buildings. As a modern method of construction, light gauge steel framing provides a valuable alternative to traditional construction methods, and is often preferred for its efficiency during installation.
Birkbeck Structures provides LGSF for all types of construction projects, working with light gauge section to form frameworks that are designed, assembled and installed strictly to unique project requirements.

Strength & Durability
Why Is Steel Faster to Build With?
Steel doesn’t need to sit around waiting to dry. Unlike concrete, which requires curing, steel frames can be assembled immediately. Birkbeck Structures fabricates every frame off-site in controlled conditions, so once it hits site, it’s ready to go. No weather delays. No curing time. Just fast, clean installation.
This parallel workflow — site prep happening while the frame is being made — means projects move forward faster. In some cases, it can cut the programme by half. That’s less labour time, tighter schedules, and quicker occupation. Especially on high-rise residential or commercial builds, speed is a serious edge.
Is Steel the Safer Option in a Fire?
Absolutely. Steel won’t burn, and it doesn’t feed fire. Unlike timber, which can ignite, or concrete, which can crack under high heat, steel holds its form. Birkbeck Structures uses light gauge steel frames with fire-resistant coatings to keep structural integrity intact even at extreme temperatures.
This makes it an ideal option for buildings where fire safety can’t be compromised — whether it's commercial units, flats, or warehouses. Combined with our ISO9001:2015 and CHAS Elite accreditations, our steel systems meet the high bar of compliance, giving you peace of mind from design to delivery.
How Does Steel Support Sustainable Construction?
Steel is endlessly recyclable — literally. At Birkbeck Structures, we use light gauge and hybrid steel frames that can be reused, repurposed, and recycled without losing performance. That means less waste and a lighter footprint over a building’s life cycle.
Plus, thanks to our off-site manufacturing, there's less site disturbance and cleaner construction. When paired with high-performance insulation, steel frames offer excellent thermal performance too. It’s a smart choice for energy-conscious developers aiming to meet modern sustainability targets — without sacrificing strength or design flexibility.
Why Is Steel Ideal for Complex Design Work?
With steel, you’re not limited by straight lines and basic shapes. Birkbeck Structures leverages precision CAD software and in-house manufacturing to create steel components that fit together without fuss. That means fewer surprises on-site, and more room to get creative with form and layout.
Whether it’s curved façades or open-plan spans, our hybrid steel systems make ambitious architecture practical. And because everything is fabricated off-site, changes don’t slow you down. From bold designs to tight footprints, steel makes it simpler to realise your vision — fast and accurately.
How Strong Is a Steel Frame, Really?
Steel doesn’t rot. It doesn’t warp. And pests won’t touch it. That’s why more developers are switching to light gauge steel for structures that last. Compared to timber or even concrete, steel stands up better to extreme weather, impact, and time.
Even better, it’s lightweight — meaning foundations can be simpler and support structures leaner. At Birkbeck Structures, we engineer frames to carry serious loads without the bulk. It’s long-lasting performance, made efficient. Whether you're building housing, offices, or light industrial units, this strength means fewer maintenance headaches down the line.

As one of the most popular modern methods of construction, LGSF holds many advantages for construction projects.
Capabilities
Applications
As a part of our expertise, Birkbeck Structures can advise on whether LGSF is suitable for your project.
Generally, this method of construction is advisable for buildings of 2 to 7+ storeys. Applications include: residential buildings, such as student accommodation, build to rent properties, as well as hotels, care homes and more.
Construction above 6 storeys can incorporate hot rolled steel components as necessary, which enhances stability and strength to achieve greater flexibility and build height. Birkbeck Structures can provide hybrid framing solutions that combine HRS and LGSF – take a look at our Hybrid Steel Frame for more information on this type of solution.
Capabilities
Our Experience
With vast experience working alongside residential and commercial sectors to provide LGSF solutions, Birkbeck Structures is able to provide an attentive service when working with contractors, architects and industry bodies.
We are able to participate in projects from as early as tendering stage, and can be involved in all stages from design to delivery and installation. We have a highly developed in-house design department for the provision of structural designs, alongside in-house fabrication departments. We deliver framework assembled, ready for installation on site.

Light Gauge Steel Framing - FAQ
LGSF is a construction method that uses cold‑formed (thin gauge) steel sections, fabricated offsite to form the building’s structural frame. The components arrive ready to assemble and are installed on site with speed and precision.
