Typically used for connecting steel balconies to structural steel frames.

Thermally-insulated connectors used for anchoring steel balconies to concrete floor slabs, which have been proven through thermal modelling to reduce heat loss compared to direct connections.

The two-part assembly consists of a cast-in anchorage and a post-fixed bracket with thermal pad located at the interface, allows for phased construction. Unlike one-piece systems which are left exposed on-site, the STC bracket component is not fixed until required reducing the risk of damage.

The bracket depth can be designed to suit the exact requirements of the application and avoid conflicts with the external cladding. The fabricated brackets are manufactured from grade 304 (1.4301) stainless steel (SSTC). Stainless steel offers the greater thermal efficiency and is essential for applications requiring enhanced corrosion protection such as coastal areas. The brackets are designed to EN 1993 (Eurocode 3) and UKCA and CE-marked to EN 1090-1.

Serrated pads and slots provide adjustability in the final bracket position without the need for stop butts or levelling shims. The thermal plate has an independently verified European reaction-to fire classification of A2-s1,d0. Anchor bars are Grade B500B and are supplied fixed to duplex stainless steel couplers. Anchorage design conforms to BS EN 1992. A stainless steel nail plate completes the assembly and features notches indicating the centreline, normally located on the centreline of the slab, to ease accurate installation.

Features and benefits:

• Proven through thermal modelling to reduce heat loss.
• Two-part assembly allows phased installation and avoids damage by other trades.
• Simple nail-plate design avoids cutting of formwork around the connector.
• Variable bracket projection to suit wall construction and avoid conflict with cladding.
• Serrated slots provide adjustability on-site for fine tuning of balcony without levelling shims.
• Bracket fabrication UKCA and CE marked to BS EN 1090-1.
• Anchorage design conforms to BS EN 1992.
• Fully stainless steel option offers the ultimate corrosion protection/ thermal efficiency benefits.
• Projection: Insert distance, consult manufacturer for available range.
