How large, long and high can a fireproof rolling shutter be made?

It is said that the fireproof rollingshutter was invented by the Japanese in 1903, but some also claim that it was invented by the Germans much earlier. The earliest fireproof rolling shutter was the steel fireproof rolling shutter.

China didn't start using fireproof rolling shutters until 1987. At that time, it was carried out as a major scientific research project. Four hardware factories were selected nationwide for trial production. Later, these four hardware factories became the "alma mater" of the fireproof rolling shutter industry, and gradually spawned many, many fireproof rolling shutter manufacturers.

From 1987 to 1994, the fireproof rolling shutters mainly used in the Chinese mainland were still steel fireproof rolling shutters, and they could only move up and down. Later, when there were more types of fireproof rolling shutters, this type was called the vertical rolling shutter.

In order to enhance the fireproof ability of the fireproof rolling shutter, people developed the composite fireproof rolling shutter. That is, on the basis of the original single-layer steel plate rolling forming of the fireproof rolling shutter, it was made into a double-layer steel plate rolling forming, and the formed fireproof rolling shutter slat was hollow, and high-temperature resistant and heat-insulating materials such as rock wool and ceramic fiber were filled in the hollow part.

History always moves forward. Around 1994, various forms of fireproof rolling shutters emerged. Of course, this is mainly in the context of the Chinese mainland. Some forms of fireproof rolling shutters had already appeared abroad or in other regions of China, but some were indeed first created in the Chinese mainland. The fireproof rolling shutters that emerged during this period included: the fireproof rolling shutter made of fireproof fabric, which was a revolutionary change in material and a very significant breakthrough, but it was not widely promoted at that time. There were also lateral fireproof rolling shutters, horizontal fireproof rolling shutters, etc. These two types of fireproof rolling shutters changed the movement form of the fireproof rolling shutter, and there were no longer only fireproof rolling shutters that moved up and down. The engineers of Fupufu began to enter the fireproof rolling shutter industry at this stage and participated in the research and development of many fireproof rolling shutters.

In 1998, some requirements were put forward for the fireproof rolling shutter, such as the fusible release function, and the standard accessory of the current fireproof rolling shutter, the fusible release device, appeared. At first, the fusible release device made of fusible metal appeared, and later the fusible release device with a glass bulb emerged. Regarding the escape function of the fireproof rolling shutter, it was proposed to open an escape door on the fireproof rolling shutter to facilitate escape. Thus, various fireproof rolling shutters with escape doors appeared, including those that opened in a flat way and those that opened by pushing and pulling. All these types of fireproof rolling shutters were first launched by the engineers of Fupufu at this stage. Of course, at this time, the engineers of Fupufu were still serving other companies.

In 1999, due to the revision of the "Code for Fire Protection Design of High-Rise Civil Buildings", the requirement of testing the temperature rise of the back fire surface of the fireproof rolling shutter was put forward. Therefore, the fireproof rolling shutter made of fireproof fabric that emerged in 1994 came to the fore. At that time, people also tried many methods to meet this requirement, but because they were all metal structures, their thermal conductivity could not be solved at that time, and all attempts failed in the end. Only the fireproof rolling shutter made of fireproof fabric finally prevailed, and thus the inorganic fabric-based fireproof rolling shutter and the inorganic super-grade fireproof rolling shutter appeared, commonly known as the single-track single-curtain fireproof rolling shutter and the double-track double-curtain fireproof rolling shutter. It was time for the engineers of Fupufu to show their talents.

Around 2002, in response to the extremely large separation width and strange shapes in buildings, the engineers of Fupufu designed the folding lifting fireproof rolling shutter, also known as the curved fireproof rolling shutter, the extra-large fireproof rolling shutter, etc. The fireproof rolling shutters are getting larger and larger. There have been extra-large fireproof rolling shutters with a length of more than 200 meters and those with a height of 16 meters, and the area has also exceeded 1,200 square meters. Such a large number of extra-large fireproof rolling shutters have greatly promoted the development of the construction industry.
