Every flood season, underground garages are among the first areas hit by urban waterlogging. Many so-called “flood doors” on the market today require tedious assembly for openings wider than 4 meters — involving center panels, external bracing, and often a bit of luck. This multi-piece construction leads to complicated installations, high error rates, and increased safety risks: if one connection point fails, the entire system is compromised. Moreover, center panels double the number of components, increase structural complexity, and create major challenges for storage, maintenance, and emergency deployment.
Project Highlights
FH-01 Quick-Fit Buckled Flood Barrier
Engineered as a single-piece structure. Withstands storms without compromise. Specifically developed for large-span underground garages and industrial openings, the FH 01 by Shanghai Weiwang Technology features a patented top compression-column system that allows a center-post-free, bracing-free design for openings up to 6 meters wide. The result is a flood barrier that is simpler, faster, and more reliable — especially in emergency scenarios.
Technical Advantages
One-piece design: Minimizes connection points, enhances sealing performance, and significantly reduces leakage risk.
Center-post-free structure: Eliminates intermediate panels, improves deployment speed, and reduces operational errors.
Large single-unit coverage: Up to 6 meters in width and 1.2 meters in height — ideal for underground garages and wide factory entrances.
Lightweight and modular: Enables fast installation and removal, perfect for repeated use and urgent deployment.
This structural innovation not only boosts efficiency but more importantly, strengthens system integrity under real-world flood conditions.
Case Study – Suzhou Takasago Construction (June 2025)
We delivered two sets of 5-meter-wide FH-01 flood barriers for the entrance of Takasago’s underground garage in Suzhou. The project adopted a full-length, one-piece structure with top compression column technology, eliminating center panels and allowing rapid, secure deployment.
Despite site constraints — including decorative metal cladding and cantilevered steel awnings — our team completed wall leveling, rail alignment, installation, and commissioning in just 3 working days, giving the client ample time to prepare for the upcoming flood season.
Why Choose FH-01
We don’t rely on “assembly” — we rely on precision.
Patented Compression Locking System: No bolts or tools required. Fast, safe, and intuitive installation.
Large-span Coverage Without Center Posts: Up to 6 meters wide per unit. Stable, seamless, and visually clean.
Easy to Store and Transport: Fewer parts, fewer panels, less logistics hassle.
Certified Performance: Passed BSI spray water pressure test with leakage under 40 L/h/m.
Multi-scenario Application: Ideal for underground garages, clean rooms, industrial entrances, equipment rooms, and more.
Conclusion
Flood protection is not optional — it’s a critical foundation for urban resilience.
When the storm hits, you shouldn’t have to scramble to assemble panels and hope the system works. Choose the FH-01: an all-in-one, high-performance, professionally tested f lood barrier solution.
