Fire Protection Network News: Fireproof rolling shutters are no different from ordinary rolling shutters. By consulting the national standards for fireproofing, it is understood that there are clear regulations in the national standards regarding the thickness of raw materials for fireproof rolling shutters: The thickness of ordinary curtain panels must not be less than 1.0; the thickness of any single panel in composite curtain panels must not be less than 0.8, and the fire resistance limit must not be less than two hours. Therefore, steel plates can all be used for fireproofing.

Compared to fire doors, fire extinguishers, and other fire-related products closely related to the home, fire curtains are mainly used in densely populated areas such as commercial buildings. They have special functions such as fire resistance, smoke isolation, suppression of fire spread, and maintenance of personnel evacuation.

Reporters visited the building materials market and the Building Materials City. When reporters entered the sales hall of the building materials market and asked which store could customize fireproof rolling shutter doors, many enterprises producing anti-theft doors and fireproof doors indicated that they could customize or purchase the product on behalf of customers.

A store that claims to be a sales agency for fireproof curtains stated that it can customize various types and materials of fireproof roller shutters. When the reporter expressed interest in installing a fireproof curtain only for their own small shop, they indicated that they could order single or double-panel, automatic or manual, and any style of fireproof roller shutter according to needs. However, there would be a difference in price per square meter due to the thickness of the steel plate material used.

Another store also strongly recommended steel fireproof rolling shutters to reporters. When the reporter asked about the differences between this type of fireproof roller shutter and ordinary roller shutters, as well as whether it could actually prevent fires, the salesperson from that store only responded by saying that they are all made of steel and can all be fireproof, but there are differences in fire resistance performance depending on the thickness of the steel plate.

After visiting several stores in the building materials market, the reporter found that many merchants have a vague concept of fireproof rolling shutters and cannot distinguish them from ordinary roller shutter doors. There is no division into Class A, B, and C as stipulated by regulations, but they are simply divided into high, medium, and low grades based on the thickness of the steel plate.

Journalists inquired about the national standards for fireproof rolling shutters and learned that there are clear regulations regarding the thickness of the raw materials for fireproof rolling shutters in the national standards: the thickness of ordinary curtain panels should not be less than 1.0mm; the thickness of any single curtain panel in composite curtain panels should not be less than 0.8mm, and the fire resistance limit should not be lower than two hours. In the market, there are many merchants who claim to be able to produce single-panel fireproof rolling shutters with thicknesses of 0.4mm and 0.8mm. This thin material is hard to believe can truly withstand a fire.
