Fire Damper Roll Forming Machine
The Fire damper forming machine produced fire damper frame, usually it is open, once fire occurs, the gas temperature of duct arrives at 70 degrees, and then the fuse protector will be fused and the damper will close under the pull of spring.It can insulate smog and fire outside.

The fishtail terminal end, as the name implies, is a type of guardrail end shape like a fishtail, that provides a shallow termination for a steel roadway guardrail fences along low speed traffic flow. The fishtail terminal is available for both W-beam and thrie beam guardrail systems and is ideal for double rail and walkways. Fishtail end terminal (end treatment) are easy to install, and can be modified for custom installations.
Fire dampers are passive fire protection products used in heating, ventilation, and air conditioning (HVAC) ducts to prevent the spread of fire inside the ductwork through fire-resistance rated walls and floors. Fire/smoke dampers are similar to fire dampers in fire resistance rating, and also prevent the spread of smoke inside the ducts. When a rise in temperature occurs, the fire damper closes, usually activated by a thermal element which melts at temperatures higher than ambient but low enough to indicate the presence of a fire, allowing springs to close the damper blades.
