It has been 5 years since the completion of Madinah Haram Piazza Shading Project, a national project by the Kingdom of Saudi Arabia. Taiyo Kogyo Corporation of MakMax Group participate in the fabrication of the 250 retractable umbrellas for the "Prophet's Holy Mosque" in Islam's Second Holy City of Al-Madinah Al-Munawwarah.
These large scale umbrellas were planned by the Saudi Arabia government to provide sunshades for the Islamic pilgrims who visit the Holy Mosque of Madinah. The large-scale umbrellas, ranging 25.5m on each side consisting mainly of equal squares, are bell-shaped suspension-tensioned membranes, which open and close automatically like folding umbrellas. The total membrane area is 162,000 square meters, and the excellent fabricating skills are required for the complex design. Taiyo began the production in April 2008 and completed the delivery of the 250th umbrella in May 2010.
The membrane material is made from 100% PTFE (Polytetrafluoroethylene) weaving material, which was developed and produced specifically for this project, ensuring the fire resistance for the safety of the pilgrims, long-term durability against the harsh Middle East weather conditions, and flexibility for everyday use. In addition, as the facility itself is a core religious site of the Islamic faith around the world, the splendorous ornamentation far exceeds the norms of any architectural concept in Japan, such as the elaborate designs coloring the membrane and the metal attachments using lavishly gilded gold.
