It is a metallic modular construction system created by architect José Rafael Oraá in the 80's, during his years of study. The structure consists of a triangular porticoed frame, made up of profiles no longer than three meters in length and nodes joined with bolts, using materials such as galvanized steel.[1]​ The system allows the development of earthquake-resistant housing solutions on irregular terrain with a reduced environmental impact, minimizing intrusive foundations with the possibility of making extensions or reductions after construction.[2]​[3]​.

The system is designed to create structures of optimal quality, allowing speed of construction, adaptability to different topographies, and reduction of seismic risk. Construction with this system allows the reduction of humidity, due to the little contact of the building with the ground and maximum use of natural light, thanks to the use of windows and skylights on the roofs. It also reduces the construction costs used for the foundations, because it uses few support points, which also reduces construction times.[4]​.

Best construction system, awarded by the Venezuelan Chamber of Construction.

Best construction stand design at the Build Housing event awarded by the College of Architects of Venezuela.[5]​.

Malaussena salon award as a multi-family housing solution, awarded by the College of Architects of Carabobo.

National award of merit to the construction industry, awarded by the Venezuelan Quality Corporation.[6]​.

The Oraaflex structural solution has spread as a commercial franchise in Latin American countries such as Costa Rica, Colombia and Panama with industrial registration and registration of an invention patent carried out by lawyer César García Urbano Taylor as an architectural solution for the construction of real estate.[7][8]​.
