Introduction to the characteristics of super-grade inorganic fabric fire-proof rolling shutter doors. Among fire-proof rolling shutter doors, special-grade inorganic cloth fire-proof rolling shutter doors have won the market because of their light curtain body and long fire resistance. They have been widely used in shopping malls and underground garages.
1. Features of special-grade inorganic fabric fire-proof rolling shutter doors:
The curtain surface is made of non-metallic materials and is sewn after special treatment. The texture is flexible and has high tensile strength. Its corrosion resistance and moisture resistance are the same as those of steel. The special fireproof roller blinds (with sprinkler device) are more unique and have better fireproof performance.
Since the curtain surface is made of non-metallic materials, the thickness of the curtain surface is small and it takes up little space. It can improve the effective use of space in the same building and also reduce the requirements for building height.
The weight of the curtain surface per square meter is no more than one-fifth of that of steel curtains, which reduces the effective load requirements of the building.
, no water curtain protection is required, water supply pipelines and control equipment are eliminated, fire water consumption is reduced, and the project cost can be greatly reduced.
, flexible start-up and low noise.
