Professional evaluation data interpretation: High density PVC curtain fabric for fast rolling shutter doors

This product is specially developed for industrial rapid rolling shutter doors, using a composite process of high-density polyester fiber base fabric and wear-resistant PVC coating. Professional testing data shows that its tensile strength can reach 5700/5100N/5cm in the warp/weft direction, and its tear strength can reach 900/80N in the warp/weft direction. It can withstand the mechanical stress of hundreds of high-speed starts and stops per day. The material has passed 100000 cycles of opening/closing testing (EN 12604) and the structure is intact without fatigue damage. Excellent peel strength ensures that the coating does not separate during high-frequency winding. The flame retardant performance meets the Level 2 self extinguishing standard and has passed the temperature resistance test from -30 ℃ to+70 ℃. The surface has undergone wear-resistant treatment, with a wear loss of ≤ 0.1mm after 100 rotations under a pressure of 4.9N, providing a durable and reliable fast isolation solution for industrial logistics channels.

Guide to Choosing High Density PVC Door Curtain Fabric for Fast Rolling Shutter Doors

1. Core indicators of dynamic durability
It is necessary to verify the tensile strength (longitudinal stress ≥ 5500N/5cm) and tear strength (longitudinal stress ≥ 900N) to ensure that they can withstand the mechanical stress of hundreds of high-speed starts and stops per day. At the same time, a 100000 cycle test report (EN 12604) is required to verify the material's fatigue resistance.
2. Wear resistance and flame retardant verification
Confirm wear test data: The wear amount after 100 rotations under 4.9N pressure is ≤ 0.1mm. The flame retardant performance needs to meet the level 2 self extinguishing standard (DIN 4102 B2 or equivalent) and meet the safety requirements of industrial sites.
3. Environmental adaptability indicators
Verify the temperature resistance range (-30 ℃ to+70 ℃) and peel strength data to ensure that the coating does not become brittle at low temperatures, does not deform at high temperatures, and does not separate during high-frequency winding. Select the weight according to the usage scenario (recommended 600-800g/㎡), and confirm the edge strengthening process to extend the service life of the door curtain.

Q: What is the durability of this fast rolling shutter fabric under daily high-frequency opening and closing?
Answer: The performance was very outstanding. Our logistics channel opens and closes more than 800 times a day, and has been continuously used for 14 months (with a cumulative operation of about 350000 times). The door curtain has no cracks or deformations, and its 100000 cycle test standard has been verified to be reliable.
Q: Can the tear resistance of materials be used after frequent collisions with forklifts?
Answer: Durable enough. After experiencing multiple forklift accidents and scratches, the measured tear strength of the door curtain still reached 870N (initial value of 900N), with no tear propagation. Its high-density base fabric and wear-resistant coating effectively resist mechanical damage.
Q: Will the door curtain become stiff and stuck during operation in low temperature environments?
Answer: Maintain good flexibility. After experiencing the winter season in the north (with a minimum temperature of -25 ℃), the fast door opened and closed smoothly without any abnormalities, and the material's performance was verified through a -30 ℃ temperature resistance test. The peel strength remains stable, and there is no coating separation phenomenon during high-frequency winding.
