Clients are welcome to visit our Caerphilly workshop to see the stunning creations we manufacture and discuss future projects, including custom railings, metal fire escapes, and building-compliant structural steels.


Designed with Durability and Detail in Mind
Steel is the material of choice for modern balcony structures due to its strength, versatility, and durability. Our steel balconies are designed to support regular use and withstand weather exposure without compromising safety or style. Depending on the building design and load requirements, we offer both cantilevered and supported systems.
We produce detailed fabrication drawings using CAD design software to ensure a perfect fit and smooth installation. Every balcony is fabricated in-house using high-grade materials and coded welding techniques, then treated with powder coating or galvanising to protect against corrosion and surface degradation.
We fabricate and install:
- Cantilevered Balconies – Minimalist, floating designs fixed directly to structural steelwork or concrete frames.
- Bolt-On Steel Balconies – Modular balcony units that can be fixed post-construction, ideal for flats and multi-storey buildings.
- Juliet Balconies – Balustrade-only installations offering safety and ventilation for upper-floor French doors or windows.
- Balcony Railings & Balustrades – Custom-designed safety railings, including glass-panelled or decorative steelwork.
- Balcony Floors – Grated or solid flooring options with drainage considerations and anti-slip finishes.
All components are made to order, ensuring architectural harmony, load-bearing integrity and long-term performance.

We provide end-to-end project management for all balcony installations across Cardiff, Newport, and the surrounding areas. From concept through to final handover, our team ensures the process runs smoothly and integrates efficiently with your build schedule.
- Consultation & Site Assessment – We assess the building structure and client goals, ensuring balcony type and placement are viable.
- CAD Design & Engineering Input – Working to precise drawings with structural support details and drainage considerations.

FAQs: Steel Frame Balconies
Planning permission depends on the type of property, the size of the balcony, and where it’s being installed. While some projects may fall under permitted development rights, many require planning approval, particularly for flats, listed buildings, or properties in conservation areas. It’s always worth checking with your local planning authority before work begins.
We offer galvanised, powder-coated, and painted finishes in a wide range of colours. These protective finishes help prevent corrosion, extend the lifespan of the balcony, and allow the finished design to complement the surrounding building.
A professionally manufactured steel balcony can last for several decades when fabricated from quality structural steel and protected with suitable finishes such as galvanising or powder coating. Regular inspections and routine maintenance will help maximise its lifespan.
A Juliet balcony consists of a safety balustrade fitted across doors or windows without a usable platform, allowing more light and ventilation. A steel frame balcony projects from the building to create a functional outdoor space that can be used for seating, planting, or recreation.
Yes. Steel balconies are commonly installed on apartment developments, private homes, offices, hotels, student accommodation, and mixed-use developments. Their strength, versatility, and design flexibility make them suitable for a wide range of building types.
