Spiral door Special Application

Spiral Special Application is a roller door developed with the specific characteristic of maintaining a high insulation. It ensures good acoustic insulation. Suitable for special applications.

The winding patented circular spiral is made of high density polyethylene and the curtain is composed of aluminum panels or double wall steel with high thermal-acoustic

insulation. The winding space is very low. It does not require anchoring to the ceiling.

Insulated industrial rolling shutters are a technological evolution in the field of doors, with the goal of dividing operational areas marked by different acoustic and thermal intensities or intended for different uses.

Hongfa Spiral Door industrial doors are part of the range of insulated shutters, which have been committed for years to providing products capable of supporting and managing every business logistics problem.

Spiral Special Application insulated door is the top of our company`s products, designed to guarantee an unrivalled level in terms of speed, safety and isolation between environments.

The thickness of the panels and their shape are the essential elements for operating in very rigid climatic conditions. In fact, the model differs because of its specific resistance to harsh temperatures and therefore to refrigerated environments.

The patented circular spiral winding is made of high-density polyethylene and the covering is composed of double-walled aluminium or steel panels with high thermal and acoustic insulation and the possibility of inserting polycarbonate windows.

Thanks to extreme response speed, minimum displacement noise, absolute safety, superior winding with reduced space requirements, due to the special processing of the curved insulated profile, Spiral 80 Special Application insulated doors are a cutting-edge product in the speed-doors sector. In addition, ceiling anchors are not required, unlike traditional speed doors. The ground impression is completely absent when the damper is open. Last but not least, it is the very attractive aesthetics, able to provide the customer with an excellent business card of its activity.

These and other innovations make Hongfa the leading company for industrial shutters in design, research and development.
