Strength and Durability of Fan

RTFANS are made from durable material that can ensure the strength of the fan. The chassis of the fan is made of imported aeronautic aluminum alloy (AA7075). It is forged by a 1000T machine with 570MPa extension strength to provide good strength. The blades are also made of high strength aircraft aluminum alloy. So, we do not compromise on the strength of our huge industrial ceiling fans.
