EFF type halogen-free coated steel spiral pipe is a halogen-free polyethylene, waterproof, sun-resistant material on the outside and galvanized steel spiral material on the inside. It is used in external, damp and liquid-tight applications with approved accessories. Although it is suitable for humid and external environments, it is ideal for use in closed areas such as subways, tunnels, hospitals and schools, where there should be no toxic smoke leaking into the environment.
