The UBM cold roll forming machine is a self-contained, trailer mounted mobile factory used for the production of steel buildings directly at a construction site. The building material is a steel coil stock. The roll forming machine is towed to the construction site where it is set up by a small crew adjacent to the building location. One set of the machines works in an entire production line, for forming, curving and cutting purposes.
The curved panels come in a traditional gable shape (straight side walls and a pitched roof), rounded double radius shape (straight side wall and broad curved roof section) or in the form of a circle arc with a fixed radius.
Finished panels are carried to an assembly area where they are connected together in groups of three using a fully patented and electrically powered seaming machine. The seamed connections are waterproof and require no bolts or other fasteners. After the three panels are assembled, they are lifted using a crane, and furnished by the builder. The panel section is then placed onto a foundation that has been prepared in advance. This process is repeated until the desired building length is achieved, of which there is no limit.
The interior building is finished as any other pre-engineered building is, and insulation, electricity, plumbing, lights, ventilators, heating and cooling systems, and partitions can be added.
