STEEL HOUSES
Official Irish Distributor of Unic Rotarex® Steel Houses
Pyramid Business Express Ltd is the official Irish distributor of Unic Rotarex® galvanised steel-frame houses, direct from the manufacturer’s factory in Romania. From compact starter homes to multi-bedroom family houses and duplexes, each structure is factory pre-cut, CE marked and engineered for Ireland’s climate and building standards.
Each house is built on a galvanised steel frame, making it fast to erect, durable and low-maintenance. Steel houses like these suit a full-time family residence, a self-build project, or a rental/investment property.

Durable Steel Frame
Galvanised steel structures resist corrosion, are low-maintenance, and are built to last for decades.

Technology
Engineered for Irish Weather
Every Pyramid steel house is built on Unic Rotarex® engineering, refined over hundreds of completed projects across Europe. Ireland’s climate brings its own demands — driving rain, strong coastal winds, damp winters — and the galvanised steel frame is designed to handle all of it without warping, rotting, or losing structural integrity over time.
Each wall, roof and floor assembly is engineered as a tested system — insulation, fire protection, soundproofing and corrosion resistance are all built in from the start. Tap a category below for details.

Thermal Resistance›
Wall buildups range from a standard 22.5 cm assembly (U = 0.27 W/m²K) up to a high-performance 32.5 cm option (U = 0.13 W/m²K), so you can choose the insulation level that suits your budget and Irish building regulations.
Fire Resistance›
Walls are clad with fire-rated plasterboard systems offering 30 to 180 minutes of fire resistance, giving flexibility to meet building control requirements for any room or party wall.
Acoustic Resistance›
Sound insulation is achieved with acoustic plasterboard, cork cladding, or fully decoupled double-stud walls between bedrooms, party walls, or duplex units — for quiet, private living spaces.
Structural & Seismic Resistance›
The light weight of a steel frame means far lower forces act on the structure during ground movement or storm loading, giving a structural safety margin that heavier masonry builds don’t have.
Wind Resistance›
Every structure is designed to withstand winds up to 150 km/h as standard — well suited to Ireland’s exposed coastal and rural sites — with higher ratings available on request.
Corrosion Resistance›
The steel frame is hot-dip galvanised with a 150–275 g/m² zinc coating, engineered for a structural lifespan of up to 98 years. Zinc is self-healing, so minor surface marks from transport or storage resolve on their own once assembled.
