Nowadays, fast rolling shutter doors run fast,have good sealing and thermal insulation performance, which is favored by factories.
But although the PVC fast door is fast, but the heat insulation and wind resistance performance is it's short board.
Although the aluminum alloy spiral high speed door can take into account all kinds of performance, but its high price makes many factories prohibitive.
Therefore, our company launched the new product of hard roller fast shutter door. Although its running speed is not as high as other fast doors, the fast running of 50cm/s basically meets the requirements of most factories. And the aluminum alloy door panel filled with polyurethane foam also ensures its good wind resistance and insulation performance.
The most important thing is affordable. Contact us for consultation.
