The hard fast rolling shutter door is indeed a good choice, but the cost is high, and it is impossible to do so large. The warehouse door of the steel plant is mainly dust-proof, and there is no anti-theft and thermal insulation requirements. It is also a good choice to choose a large-scale fast stacking door. , Jiyuan Iron and Steel and Zhangjiagang Shagang in the industry all use large-scale fast accumulation doors, also known as strap-type fast rolling shutter doors, to block the leakage of internal dust and meet the production requirements of environmental protection, hygiene and dust-free.

    1. Wind pressure resistance: When choosing a suitable gate for a 10*10m hole, first of all, ensure good wind resistance. Because the larger the size of the door opening, the greater the pressure it needs to bear. The accumulation structure means that there are multiple straps in the ascending method. Quickly lift it up, and in the middle is a large steel pipe as a wind-resistant rib, and the wind and compressive performance can reach grade 8-10.

    2. Dust blocking: The stacked fast rolling shutter door is an upgraded version of the fast door. The airtightness is to retain the original high-quality brush seal to resist internal dust, run into the atmosphere, and produce pollution to the environment.

    3. Fast lifting: The lifting speed of the fast stacking door is faster than that of the steel roll door and the swing door. The automatic induction method is installed, which is suitable for the frequent entry and exit of warehouse forklifts, which is convenient and dustproof and easy to use.
