Weiwang Technology Builds FM-Grade Flood Protection for C&D Trojan (Shanghai) Energy Technologies Co., Ltd.
Introduction：With extreme weather events becoming more frequent, high-tech manufacturing facilities must ensure uninterrupted operations.
The raw-material warehouse of C&D Trojan (Shanghai) Energy Technologies Co., Ltd. included a 9.8-meter ultra-wide opening. Once floodwater enters, raw materials and equipment would face significant risks.
Shanghai Weiwang Technology Co., Ltd., following FM 2510 standards, delivered a truly reliable flood-protection system for the facility.
01｜Challenge: 9.8-Meter Ultra-Wide Opening with High Exposure Risk
Site inspection revealed that the warehouse’s lift platform created a massive 9.8-meter ingress channel for floodwater.
Traditional bolt-fixed flood panels cannot maintain structural integrity and sealing performance at this span, nor can they be deployed quickly enough for sudden flood events.
02｜Solution: FD-02 Quick-Fit Buckled Flood Door
For the ultra-wide opening, we adopted the FD-02 Quick-fit Buckled Flood Door, fully compliant with FM Approvals 2510.
Key Technical Highlights：
① Tool-Free Quick Installation — Eliminates Bolt-Related Risks
The buckled quick-fit structure avoids issues such as bolt corrosion, thread stripping, or loss. The tensioning lever ensures consistent sealing pressure with every lock.
② Ultra-Wide Stabilized Design: Center Post + Diagonal Bracing
A removable center post and diagonal bracing distribute hydrostatic loads, ensuring the 9.8-meter span maintains zero deformation and zero leakage.
③ Modular Rapid Assembly
Two operators can complete the installation and locking of the entire door within 3 minutes, significantly improving emergency response speed.
03｜Testing: Passed FM’s “Dynamic Spray Test”
To verify sealing performance, we conducted a dynamic spray test rather than a simple static water-seal test:
- Method: Use a 1.5 m³/h high-pressure pump to repeatedly spray along the joints at a distance of 2–3 meters.
- Requirement: No leakage or water marks on the dry side.
Result: 0 leakage｜100% pass rate.
The dry-side wall, floor, and door panel remained completely dry throughout the entire test and after completion.
04｜Delivery: More Than a Product — A Complete Flood-Protection Capability
We provided on-site operator training to ensure the client can complete the full deployment process — from retrieval to assembly — in the shortest time possible.
We also developed a maintenance program for them:
- Monthly inspection: Check EPDM seals and track cleanliness
- Annual maintenance: Conduct simulated testing to ensure the system remains ready for use at all times
Conclusion
From risk assessment and structural design to strict testing and operator training, Weiwang Technology delivered not just a flood door for C&D Trojan (Shanghai) Energy Technologies Co., Ltd. — but a verifiable, auditable, and truly flood-resistant protection system.
