In 1983, Isfahan province’s Khooneh Engineering Company (Private Joint Stock Company) was founded. This company’s primary operations include designing, manufacturing, and installing all prefabricated and prestressed concrete and metal structures.

Along with prefabricated structural components, the company has equipped and launched pre-tensioned part manufacturing equipment from Italy to expand its design and execution capabilities. Hollow-core roof slabs, walls, columns, and beams are now in production, with the following benefits:

• The elegance of prestressed constructions in comparison to prefabricated and situ structures under the same circumstances
• Reduce the ceiling height to enhance the usable height of the floors
• Acoustic ceilings. Sound absorption and reduction caused by ceiling holes
• Production of high openings to increase the distance between columns and expand the architectural application of spaces
• Use of hollow-core slabs to pass electrical and mechanical installations
• Increase bearing capacity at different openings and deflection control
• Other benefits of concrete constructions include fire resistance and quickness of construction
