The company's original research and development of new materials - CTS. CTS Slab (Core Tubular Steel) is the technical term for the prefabricated panels made out of BCORE. The parts of a CTS Slab are prefabricated in the factory and installed on site, which greatly reduces assembly time unlike concrete constructions, thus freeing the construction site from dust, noise and waste. The structures made out of CTS slabs have the advantage of energy conservation, earthquake resistance, long service life and can be completely recycled. A CTS Slab is made out of thin-walled core tubes, sandwiched between two steel plates. The flanged edge of the core tubes increases the area of connection to the steel plates. The core tubes are integrated onto the steel plates by the use of a thin layer of copper coil foil placed between them and then melted together in 1100°C hot air ovens in order to create a very firm joint. A standard CTS Slab is 12m long, 2m wide and 0.15m thick. They can be used as load-bearing columns, beams or floors. They can be also cut into smaller pieces depending on the design. The building process from CTS slabs consist of three phases; First phase: CTS slabs are manufactured in factory. The core tubes and plates are welded into slabs and then processed into specific shapes like beams or columns, according to the design requirements. Second phase: CTS slabs are transported and assembled on site, forming main structure with sheer walls, columns, beams etc. Third phase: Elements such as doors, windows, balconies, handrails and stairs are installed along with interior finishes and electromechanical installations.
