Seppes E-type Oversized Fast Rolling Door

Product Name:E-type oversized fast rolling door

Product introduction: E-type super large speed roller shutter door, specification of 25 square meters, all-round safety protection system and maintaining the characteristics of fast opening and closing, is one of the basic fast door products of Xilang door industry.

Door Curtain Structure
The curtain adopts a cold splicing process to reduce deformation when heated, ensuring a flatter surface.

Limit Structure
The planetary pointer limit is one of SERANG’s core technologies, offering the smallest steering difference and highest accuracy among traditional mechanical limits.

HMI System
SERANG’s unique human-machine dialogue window maximizes the convenience of industrial door operation and maintenance.

Variable Frequency Control System
Each speed gate is equipped with a high-quality frequency converter, improving overall performance.
