Project: Deqing Imerys Flood Barrier Project | FM 2510 Field Test Record
When the flood comes again, the line of fate is only a door away.
Heavy rain gives no warning. Three days of continuous downpour, drainage channels boiling, water rising in the night.
Outside the Deqing Imerys (Zhejiang) Zirconia Co., Ltd. plant, the flood approached—1.5 meters high, chest-deep, enough to overwhelm equipment, control cabinets, and storage facilities.
At the entrance, an FM-certified flood door had been pre-secured. The locking rods were tightened in less than three minutes.
Water levels rose: one meter, 1.2 meters, up to 1.5 meters. Outside, waves crashed; behind the door, it remained dry.
The data from that test now serves as a footnote to this reality:
Under 1.5 meters of water pressure for 120 minutes, only 560 mL of leakage occurred—less than half a cup, performance 12 times stricter than the international limit. What it ensured was uninterrupted production, equipment safety, and data integrity.
In increasingly frequent extreme weather, a flood door is not just “disaster equipment,” it is what allows a company to choose which side of the flood and order to stand on.
When the waters rise again, some come to a halt, others keep running.
The difference lies in—who secured that half-cup distance in advance.
