Smoke Curtains

Automatic Smoke Curtains are advanced smoke control curtain systems designed to limit, contain and channel smoke movement inside buildings during a fire emergency.
Unlike fire curtains, whose primary purpose is to provide fire compartmentation against direct fire exposure, an automatic smoke curtain primarily supports smoke management. When activated by a fire alarm or smoke detection signal, the curtain automatically descends from a concealed headbox to a predetermined design position, helping form smoke reservoirs, control smoke migration and direct smoke toward designated extraction areas.
Manufactured by Huadun Door Industry, a professional Automatic Smoke Curtain manufacturer, smoke curtain manufacturer and OEM supplier, the system combines heat-resistant flexible curtain fabric, roller assembly, compact headbox, motorized drive and intelligent fire alarm interface into a project-specific smoke control solution.
Automatic deployment allows the curtain to remain concealed during normal building operation while becoming part of the building's smoke management strategy during an emergency. This makes automatic smoke curtains particularly suitable for atriums, escalators, stair openings, shopping malls, airports and other large open spaces where permanent smoke barriers would interfere with architectural design or daily circulation.
Huadun provides customized Automatic Smoke Curtains, Active Smoke Curtains, Smoke Control Curtain Systems and OEM manufacturing for international projects.

Fixed Smoke Curtain is a permanently installed passive smoke barrier designed to restrict the horizontal movement of smoke beneath ceilings and support effective smoke control during a fire emergency. Unlike an automatic smoke curtain, a Fixed Smoke Curtain remains in its operating position at all times and requires no motor, roller, control panel or automatic deployment system.
Manufactured by Huadun Door Industry, a professional Fixed Smoke Curtain manufacturer and OEM supplier, the system combines heat-resistant flexible smoke barrier fabric, durable mounting profiles and a reinforced bottom rail to provide a reliable and low-maintenance smoke containment solution. The Static Smoke Curtain is primarily used to create smoke reservoirs, divide large ceiling spaces into controlled smoke zones and guide smoke toward natural or mechanical smoke extraction systems. Its lightweight design allows easy integration into commercial, industrial and public buildings without affecting the building's architectural appearance.
As an experienced Smoke Curtain manufacturer, Huadun provides customized Fixed Smoke Curtains, Static Smoke Curtains and Passive Smoke Barrier solutions based on project dimensions, ceiling layouts and smoke-control requirements, with OEM manufacturing and engineering support for global construction projects.
