Creating Outdoor Space Without External Columns
Cantilevered balconies extend beyond the building façade, providing usable outdoor space without requiring supporting columns beneath the projecting structure.
By transferring loads back into the building, cantilevered balconies create an open appearance while offering flexibility in size, shape and architectural detailing. They can incorporate glass balustrades, decorative metalwork and a variety of finishes. Alloy Fabweld manufactures and installs cantilevered balcony structures for residential developments, working with project teams to accommodate complex designs and building requirements.

How Are Cantilevered Balconies Supported by Buildings?
Cantilevered balconies transfer substantial forces into the supporting structure, making connection design and structural coordination essential. Engineers must consider loading, deflection, fixing arrangements and the capacity of the building to resist these forces. Where connections pass through the insulated building envelope, thermal bridging and weatherproofing also require attention. Alloy Fabweld works with project engineers and contractors to develop buildable fabrication details, coordinate structural interfaces and plan installation around the approved design.
