Fabric door is an essential equipment of dust-proof sealing and explosion proof for large sand blasting and painting workshop. Its qualities in sealing, explosion-proof, anti-typhoon, anti-earthquake and operational safety protection etc. are directly affecting the customer’s production safety and cost-effectiveness. Our fabric doors have the following unique characteristics in design and manufacturing:
● The truss structure of the vertical lift fabric door’s upper and lower cross beams and horizontal frame are optimized by design with all nodes mechanically calculated and analysed.
● The door is equipped with advance safety braking device.
● Sealing of the junction between the door and column trails is by rubber fender type structure.
● Lifting of the door is by hoist mechanism.
● Safety side door is by manual open and close structure.
● Bottom sealing of the door is by U-shaped rubber fender type structure and durable.
● The Multi-stage Protection for Safety of Lifting.
● Door: It is comprised of PVC fabric material, bottom cross beam, middle frame. The door has two layers of high strength PVC flame resistance fabrics which can bear shots hit and flame resistance.
● Drive system: it is made of reducing motor, steel rope drum, steel rope, guiding wheel and so on.
● Wind resistance: 68~75kg/m2

◆ Advantages
● High-Efficiency Sealing:The vertical lifting fabric door uses high-quality fabric material, providing excellent sealing performance to effectively prevent external air, dust, pollutants, and harmful gases from entering the sandblasting and coating workshop. This ensures a clean and safe environment within the workshop, preventing harmful substances from spreading to the outside.
● Fast Lifting Operation:This fabric door is equipped with an electric lifting system, allowing for rapid opening and closing to meet the needs of frequent entry and exit within the workshop. Compared to traditional rolling or sliding doors, the lifting door is more efficient and convenient to operate, improving workshop productivity.
● High Durability:The high-strength materials used in the fabric door can withstand friction and impact during long-term use, exhibiting excellent wear resistance and tensile strength. Even in high-frequency use environments, it maintains good performance, extending its service life.
● Energy Saving and Environmental Protection:Because the fabric door effectively isolates the effects of external climate, it reduces energy loss from internal air conditioning or heating systems, achieving energy savings. Its sealing design also reduces equipment and environmental pollution, meeting environmental protection requirements.
● Energy Saving and Environmental Protection:The fabric door effectively isolates the workshop from the influence of external climate, reducing energy loss from internal air conditioning or heating systems, achieving energy savings. Its sealing design also reduces equipment and environmental pollution, meeting environmental protection requirements.
● High Flexibility
Vertical lifting fabric doors not only adapt to the needs of various sandblasting and coating workshops but can also be customized according to different sized entrances and exits, ensuring smooth entry and exit for different types of workpieces, increasing operational flexibility and convenience.
● Easy Maintenance
Compared to traditional metal doors, fabric doors have lower maintenance costs. Only periodic inspection and cleaning of the door body and lifting system are required to ensure normal operation; frequent repairs or replacement of parts are unnecessary, reducing maintenance costs.
● Wind and Pollution Resistance
These fabric doors possess strong wind resistance, adapting to various environmental conditions, making them particularly suitable for use in windy or unpredictable climate areas. Simultaneously, their design effectively prevents pollutants from leaking out of the workshop, protecting the surrounding environment.
