After years of research and investigation into lightweight bolt and nut structures, a design was presented to the Patent Office at the beginning of 1396. After three months of scrutiny in the specialized structure department of the Center for Road, Housing, and Urban Studies, this innovation was registered as a new invention under the name DSF structure, and the Diako Space Structure company was established with registration in the Companies Registration Office.
In 1356, the Development of Coating Company, under the management of Engineer Hassanzadeh, the first specialized sandwich panel installer, started its journey and has accumulated over 40 years of experience in designing and manufacturing various prefabricated buildings.
In 1396, the innovation and patent registration of DSF technology, with registration number 91797, was accomplished by Engineer Hassanzadeh. The exclusive operating rights were then handed over to the Clean Technology Ambassador Company.
DSF spatial structures, during the past seven years, have evolved from the idea stage, involving the design and construction of molds and the establishment of production lines. It has transformed into a technology with an experience of designing and building over 45,000 square meters of structures (all of which have engineering organization approvals) to its credit up to the present day.
