Advanced, light gauge steel panel systems

British Offsite is the creator of UNisystemLB (loadbearing) and UNisystem (non-loadbearing), the most technically advanced, light gauge steel panel systems in the marketplace.

Adaptable to any design vision, our solutions are suitable for housebuilding, mid-rise and high-rise developments, and for the construction of commercial and public buildings.

We manufacture our panels at our flagship factory Horizon, in the heart of Essex, using state-of-the-art robotics, designed with Randek UK. We have the capabity to produce 110,000 lm – the equivalent of 4,000 homes per year. A complete set of panels for one aparatment can be manufactured every 60 minutes.

Low to mid-rise developments

UNisystemLB (loadbearing) is designed for use in low to mid-rise developments – buildings of up to six storeys, with a maximum finished floor height of 18 metres.

Every component of UNisystemLB will be familiar. The only difference is we're bringing them together on our automated assembly line, to produce consistent quality panels and to deliver dry building envelopes faster.

Mid to high-rise structures

UNisystem non-loadbearing is designed for use in mid to high-rise developments of over six storeys and up to any finished height.

The non-loadbearing components, UNipanel (external walls) and UNiwall (internal walls) operate as infill panels, working in conjunction with a loadbearing steel or reinforced concrete structure that delivers vertical load transmission and flooring.

Once panels are lifted into place and secured, you have dry building envelopes. Internal fit out can begin on lower floors, while panels are still being lifted into place on floors above.
