Structure
The hose is manufactured from stainless steel (commonly SS304) with corrugated design for flexibility, and an additional braided stainless-steel outer layer for reinforcement. This outer braid enhances resistance against bursting, cracking, and external impacts.
Manufacturers also supply a full range of installation accessories such as ceiling brackets, support bars, couplings, threaded outlets, and clamps to ensure quick installation and compatibility with different sprinkler systems.
