SFS Contractor, Installation & Complete SFS Packages
Steel Framed Systems (SFS) are transforming modern construction across London, offering a faster, more efficient, and highly precise alternative to traditional building methods. From high-rise residential developments to commercial structures, SFS is now a preferred solution for developers seeking performance, speed, and sustainability.
As an experienced SFS contractor in London, BAS Frames delivers complete solutions—from design and supply to full SFS installation and project delivery. This guide explains everything you need to know about Steel Framed Systems, including how SFS packages work, the installation process, and why choosing the right steel framing specialist is critical.
What Are Steel Framed Systems (SFS)?
Steel Framed Systems (SFS) are lightweight, cold-formed steel structures used to create non-load-bearing external wall infill systems. These systems are fixed to a primary structure (steel or concrete frame) and provide support for insulation, sheathing, and external cladding.
Typical SFS components include:
- Galvanised steel studs and tracks
- Insulation layers for thermal performance
- Vapour control and breather membranes
- Sheathing boards and cladding support systems
SFS is widely used across London due to its adaptability, precision manufacturing, and ability to meet strict building regulations.
What Is Included in an SFS Package?
A complete SFS package ensures that every stage of the system is handled efficiently and professionally, reducing risk and improving coordination on site.
At BAS Frames, an SFS package typically includes:
- Design & Engineering – Detailed drawings and structural coordination
- Material Supply – High-quality steel components from trusted manufacturers
- SFS Installation – Full on-site assembly by experienced teams
- Project Management – Coordination with main contractors and other trades
- Quality Assurance – Compliance with UK standards and project specifications
By choosing a full-package solution, developers benefit from a streamlined process with fewer delays and better cost control.
The SFS Installation Process
Professional SFS installation plays a crucial role in ensuring structural performance, programme efficiency, and long-term durability.
The installation process typically involves:
- Site Preparation & Setting Out
Ensuring alignment with the primary structure and verifying tolerances - Installation of Steel Framework
Fixing vertical studs and horizontal tracks to form the structural grid - Integration of Insulation & Membranes
Enhancing thermal efficiency and moisture control - Sheathing & Cladding Support
Preparing the structure for external finishes - Inspection & Quality Control
Ensuring compliance with design and safety standards
Because SFS components are prefabricated, installation is significantly faster than traditional construction methods—making it ideal for fast-paced London developments.

Frequently asked questions
What are Steel Framed Systems (SFS) and where are they used in London?
Steel Framed Systems (SFS) are non-load-bearing infill walls built from cold-formed steel studs and tracks, fixed between the floors of a concrete or steel primary frame. In London they are widely used on mid- and high-rise residential, commercial and mixed-use buildings, where their light weight and fast installation suit constrained city-centre sites.
Why hire a specialist SFS contractor in London?
London projects bring restricted access, tight programmes and strict fire-safety requirements, especially on buildings over 18 m. A specialist SFS contractor manages design, supply, installation and compliance documentation as one package, reducing coordination risk for the main contractor.
What is included in a London SFS installation package?
A full package covers structural design and calculations, supply of cold-formed sections and sheathing, on-site installation, deflection-head and cavity-barrier detailing, and quality and handover documentation. Confirm at tender stage whether design and firestopping are included.
How fast can SFS be installed on a London project?
Installation rates depend on access and wall height, but SFS is typically far quicker than blockwork and can be installed in parallel with other trades, helping protect tight London programmes. BAS Frames provides project-specific programme estimates from drawings.
