Freestanding Steel Frames for Complex Installations
Freestanding steel sub frames are particularly useful where an existing building cannot provide suitable structural support, or where an independent framework offers a more practical solution.
Our bespoke systems can be designed to:
Support balconies, roof terraces and elevated platforms.
Reduce reliance on existing load-bearing structures.
Accommodate challenging building layouts and site conditions.
Integrate with glass balustrades and architectural glazing.
Incorporate suitable foundations and structural connections.
Provide durable support for residential and commercial projects.
Every installation is assessed individually, with loading requirements, ground conditions and structural stability considered during the design process.
For projects requiring additional foundation support, we can also coordinate specialist piling solutions and structural steel fabrication.
