Lightweight Steel Frame Infill Systems
Lightweight Steel Frame Infill Systems
Our Lightweight Steel Frame Infill Systems deliver fast, efficient weatherproofing solutions—achieving up to 50% quicker enclosure than traditional building methods, helping you meet tight project deadlines and reduce overall construction time.
Precision, Flexibility, and Structural Integration
Designed to seamlessly integrate with both concrete and structural steel frameworks, our infill system uses precision-cut studs assembled through a stick-build method, enabling rapid installation and swift weather-tightness. The system’s flexibility accommodates structural movement and varying degrees of deflection, ensuring durability and stability throughout the building’s lifecycle.
Cost-Effective Solutions for Mid-Rise Buildings
Paired with a broad range of sheathing boards, our infill solutions are suitable for mid-rise buildings up to and beyond 18 metres in height. This lightweight steel approach not only accelerates build progress but also offers significant cost savings—making it the smart choice for modern developments seeking quality, speed, and efficiency.
Common Applications of SFS Infill Systems
SFS Infill Systems are widely used across many building types due to their lightweight strength, precision, and speed of installation. They are commonly applied in apartment buildings, retail units, hotels, blocks of flats, leisure centres, schools, and a wide range of commercial steel frame buildings. As the construction industry increasingly adopts faster and more efficient building methods, the popularity of SFS infill has grown rapidly. With advantages including structural strength, design flexibility, rapid enclosure, and long-term durability, it’s clear why light gauge steel framing and steel frame infill systems have become the preferred choice for modern developments.
Benefits of SFS
Strength steel is extremely robust and can withstand massive loads compared to timber frame frameworks. Its greater density implies that steel frames, although heavier than timber or concrete, can support heavier loads on beams of similar dimensions.
Time-saving steel frames are prefabricated, which means they can be assembled (via welding or bolting) on-site.
SFS allows for a quick and easy installation when time is of the essence.
Flexible steel can be cut and adjusted to the exact specifications you want. It is therefore adaptable and suitable for a wide range of diverse designs. Using a steel frame allows you to build an extremely solid structure and bring a unique design to the world. Steel frames made of structural steel are easily adaptable or modifiable if any remodelling or expansion work is planned.
Durable SFS lasts much longer than concrete or timber. Steel is not prone to splitting or cracking as it ages. If the Steel is properly primed or finished, it will not be inclined to corrosion and will also not become warped or rot when exposed to humidity.
Cost-effective because SFS are manufactured off-site, you will be able to reduce your on-site costs. As we mentioned in the fourth point, Steel is extremely durable, so the costs for maintenance or repairs will be substantially smaller.
Sustainable Steel is completely recyclable, which will significantly reduce your carbon footprint.
Safe steel is a non-combustible substance that does not cause a fire. An SFS structure framing method can help protect the structural integrity of a structure when faced with extreme weather conditions.

FAQ
What is SFS infill?
SFS infill is a lightweight steel frame system used to create internal and external wall structures between concrete floors or steel frameworks. It provides rapid installation, excellent strength, and efficient weatherproofing for mid-rise and high-rise buildings.
Why is SFS used in modern construction?
SFS is chosen for its speed, precision, and durability. It offers faster enclosure compared to traditional methods, reduces on-site labour, and delivers a strong, fire-resistant structure suitable for residential, commercial, and industrial buildings.
Is SFS suitable for rooftop extensions?
Yes. Lightweight steel frame systems are ideal for rooftop extensions due to their low weight, high strength, and minimal impact on existing structural load. This makes SFS a preferred option for adding new floors to existing buildings.
How does lightweight steel framing compare to timber or concrete?
Steel framing is stronger, more durable, and more resistant to fire, moisture, and deformation. It offers greater design flexibility and requires less maintenance over time than timber or concrete systems.
What types of buildings use SFS systems?
SFS is commonly used in apartments, hotels, retail units, schools, leisure centres, commercial buildings, rooftop extensions, and steel frame homes. It is suitable for both new builds and refurbishment projects.
What are the main benefits of SFS construction?
Key benefits include rapid installation, high structural strength, design flexibility, excellent durability, sustainability through recyclability, and strong fire performance.
