When designing fire protection systems for projects with suspended ceilings (commercial centers, office buildings, apartments), in addition to ensuring the correct design and safety for the whole system, ensuring that sprinkler heads are installed at the correct position is extremely important. This is to ensure the fire protection system works effectively in the event of an incident.
Although commonly used in many different projects, hard pipes bring many difficulties and obstacles for the contractor to ensure that the installation process is carried out correctly and synchronously. With many outstanding advantages compared to hard pipes, the introduction of flexible sprinkler hose is an alternative solution to solve many problems that hard pipes are still facing. With great flexibility, rigorously tested and meet quality standards, quick construction time, flexible sprinkler hose has been used in many countries around the world, including Vietnam.
