Steel framing system (SFS) accessories work alongside SFS studs to form strong, efficient building envelopes. From connectors to thermal bridging solutions, SFS accessories address critical construction challenges.
They enhance insulation, enable flexible connections, and ensure proper load distribution across the framework.
What Are the Different SFS Accessories?
SFS accessories cover a wide range of essential components in steel frame construction:
- Bracing straps: Provide lateral support and enhance structural stability
- Brick tie channels: Connect external masonry to steel framing
- Deflection head brackets: Allow vertical movement between floors
- SFS screws: Designed for specific connections within SFS builds
- Zed bars: Act as thermal breaks to reduce heat transfer
- Tek screws: Self-drilling fasteners for metal-to-metal SFS connections
Is a Deflection Head Bracket Recommended Over Other SFS Connections?
Deflection head brackets are ideal for multi-storey SFS buildings where vertical displacement may occur due to settling or live load deflection.
They maintain non-load-bearing wall integrity, preventing damage such as drywall cracking. These brackets are especially beneficial in tall partitions and structures exposed to thermal expansion from temperature changes.
4 Benefits of Tek Screws for Metal Connections in SFS Framing
- Holding power: Tek screws deliver a strong grip for secure metal joins
- Quick installation: Self-drilling tips eliminate the need for pre-drilling, saving time
- Versatility: Available in various sizes and thread patterns for different SFS stud types
- Corrosion resistance: Protective coatings make them suitable for internal and external use
How Do Zed Bars Contribute to Thermal Performance in SFS Exterior Wall System?
Zed bars enhance the thermal efficiency of exterior SFS wall systems by acting as thermal breaks. They separate inner and outer layers, reducing heat loss through conductive materials like steel.
They also offer a structure for extra insulation outside the main stud layer and help with moisture control when installed properly, adapting insulation thickness to meet energy codes.
How Does the Gauge of Brick Tie Channels Affect Their Load-Bearing Capacity?
The gauge of brick tie channels significantly impacts their structural strength in SFS applications:
- Thicker gauge = higher capacity: Lower gauge numbers (thicker metal) support greater loads
- Material strength: Higher gauge improves resistance to bending and twisting
- Wind load resistance: Thicker channels are ideal for high-wind environments
- Span capability: Heavy-gauge channels allow wider stud spacing, reducing material use
- Durability: Increased corrosion resistance and extended lifespan
