Introduction to Flood-Proof Doors & Swing-Hinged Flood Gates
Unlike single-panel or modular barriers that need manual assembly before a storm, swing-hinged flood gates work like standard doors. No daily setup. No manual handling. They integrate into building designs, are made of stainless steel, and resist high winds and water pressure. Perfect for high‑traffic areas, these flood‑proof doors save significant manpower and provide rapid, reliable defense before typhoons or black rainstorms hit.
Applications of Swing-Hinged Flood Gates
Heavy‑duty swing‑hinged flood gates are widely used in large underground car parks, basement malls, and wide entrances (10 meters or wider). Because they are permanently installed, there’s no need for lifting, storage, or temporary assembly during dry season. Closing the door instantly activates full flood protection.
Due to their large dimensions, these flood‑proof doors require custom engineering to match the building’s original architectural design. Permanent installation is more complex, so the initial cost is typically higher than that of demountable barriers and single‑panel flood barriers, both of which require manual installation.
- Responding to Flash Floods: Robust hinged design, secure and reliable. When a storm warning sounds, simply push the gate shut and lock it. Flood defense activates in seconds , no assembly, no road closures, no disruption to busy entrances.
- Access Point Protection: Commonly installed at building main entrances, garage gates, basements, loading docks, and switch rooms. In Hong Kong, these flood-proof doors are extensively used to protect underground car parks and switch rooms.
International Material Specifications: Engineering Durable Flood-Proof Doors
Tachibana flood‑proof doors feature precision‑machined, self‑lubricating hinges, allowing a single person to easily open or close the swing‑hinged flood gates without effort. Other core industrial material specifications include:
- Embedded U‑Channel (316 SS, 5mm) : Maximum compression resistance and anti‑seepage when cast into concrete.
- Side Mullions (316 SS) : Provides a rigid, wind‑resistant frame for wide‑span gates.
- Panel Structure (316 SS) : Square‑tube core with faceplates for resilience against wave impact.
- Hardware (Hilti anchors + 316 SS screws) : Rust‑proof and jam‑proof in humid environments.
- Sealing Gaskets (EPDM) : Weatherproof, high‑rebound, anti‑aging for long‑term sealing.
- Quick‑Action Lock : Instant locking for emergencies. Panels include clear labels and tags.
