Sliding Flood Door Gate
The Madoors USA Sliding Flood Door Gate is a hydraulically operated automatic sliding flood gate system providing complete leak-proof flood protection at garage entrances, shopping center entrances, factory access points, apartment buildings, institutions, and organizations — with an air seal that inflates when the door closes to seal all leak points, solid mechanical hydraulic construction that keeps floodwater completely in front of the gate with zero passage to the protected side, ship-type Jotun paint or hot-dip galvanization for rust protection, stainless steel construction option, 380V/220V AC and 24V DC operation, solar-charged battery backup for power-failure operation, and remote phone-button closure for operation from any location during flood emergencies. All Madoors USA sliding flood door gate systems carry a 2-year guarantee, are manufactured to customer-specific dimensions and structural requirements, and are available in standard sliding, telescopic, and circular inclined wing configurations.
TECHNICAL SPECIFICATIONS
The Madoors USA Sliding Flood Door Gate operates hydraulically — the hydraulic drive system provides the high force required to move the gate against the wind loading, debris impact, and initial water pressure encountered during flood deployment while maintaining reliable operation throughout the full gate travel. The mechanical system is manufactured to the highest structural standards — the gate body, rail system, sealing frame, and hydraulic mechanism are all engineered for the extreme loading conditions of active flood events where the gate must hold against continuous hydrostatic pressure without mechanical failure or seal deterioration.
The air seal inflates automatically when the door reaches the closed position — the pneumatic inflation of the perimeter seal compresses it against the gate and frame contact surfaces to close all potential leak paths. The inflated air seal provides complete leak-proof isolation — floodwater cannot pass through any point of the gate perimeter when the seal is inflated and the door is in the closed and locked position. This active inflation sealing provides more reliable zero-leak performance than passive compression seals that depend on door closing force alone.
The gate is manufactured to customer-specific dimensions — width, height, and structural configuration are designed for the specific entrance geometry of each installation. The structural condition of the entrance — wall material, threshold construction, floor level, and approach geometry — is assessed for each project and the gate design is adapted accordingly.
For entrances where the opening travel distance is insufficient for a standard single-panel sliding gate, the telescopic configuration provides multiple overlapping panels that retract into a shorter stacked open position — enabling sliding flood gate installation at entrances where a single panel would require more open travel space than is available. The circular inclined wing configuration provides an alternative gate geometry for special entrance conditions.
Power supply is available at 380V and 220V AC and 24V DC. Solar-charged battery systems provide uninterrupted operation during power failure — the solar panels charge the battery continuously during normal conditions, and the battery provides gate operation power during the power outages that frequently accompany flood disaster events. Remote phone-button control allows the gate to be closed from any remote location even during power failure and disaster conditions — the gate operator activates the solar battery-powered gate closure from their mobile phone while away from the facility.
Rust protection options include Jotun ship paint for standard corrosion protection, hot-dip galvanization for the maximum available corrosion resistance where dimensions permit, and stainless steel construction for permanently wet, coastal, or chemically aggressive installation environments.
KEY FEATURES
Hydraulic Drive — High Force Reliable Operation
The hydraulic drive system provides the consistent high force required for reliable gate operation under the loading conditions of real flood events — wind-driven debris impact, rising water pressure against a partially closed gate, and the static gate weight over the full gate travel are all managed by the hydraulic drive without the speed reduction, stall risk, and force inadequacy that electromechanical drives experience under flood loading. Hydraulic force reliability directly ensures that the gate always reaches the fully closed and sealed position when flood deployment is initiated.
Inflating Air Seal — Complete Leak-Proof Isolation
The automatically inflating air seal that closes all leak points when the door reaches the closed position provides active, verifiable leak-proof isolation — the inflated seal conforms to the contact surface geometry at every point of the gate perimeter, closing gaps that would allow water infiltration under hydrostatic pressure. The inflation seal directly provides the most reliable zero-leak performance available for sliding flood gates, confirmed by the operational principle that floodwater definitely cannot pass to the other side when the seal is inflated and the gate is closed.
Remote Phone-Button Closure — Disaster Scenario Operation
The remote mobile phone button closure capability addresses the most critical practical challenge of flood gate operation — the flood event may develop rapidly while the facility operator or owner is away from the premises. Remote phone closure allows the gate to be deployed from any location with mobile phone coverage, directly enabling flood protection activation without requiring physical presence at the gate. This remote operation capability is particularly valuable for the flood scenarios that develop rapidly during overnight hours, during periods when the facility is unoccupied, or when access to the facility is blocked by the flood itself.
Solar Battery Backup — Power-Failure Flood Operation
The solar-charged battery backup provides uninterrupted gate operation during the power failures that commonly accompany flood disaster events — the solar panels charge the battery during normal conditions, and the battery provides the gate drive power when the mains supply fails. This solar battery independence directly ensures that the flood gate remains operable throughout the flood event regardless of the power supply status — flood gates that cannot operate during power failures provide no protection in the most severe flood events where power infrastructure is the first casualty.
Telescopic Configuration — Short Opening Constraint Solution
The telescopic flood gate option resolves the installation constraint of entrances without sufficient open travel space for a standard single-panel sliding gate — multiple overlapping panels slide and stack into a compact open position that fits within the limited available travel space. This telescopic capability directly extends flood gate installation to entrances that standard sliding gates cannot serve, expanding the protected facility types to include constrained urban ground floor entrances, underground parking access points, and any entrance where the opening travel distance is limited by adjacent walls, columns, or infrastructure.
Jotun Ship Paint & Hot-Dip Galvanization — Long-Term Corrosion Protection
The Jotun ship paint coating — the same corrosion protection standard used on marine vessel hull structures continuously exposed to seawater — provides the highest available paint-based corrosion protection for flood gate steel in outdoor and flood-exposed environments. Hot-dip galvanization provides even greater corrosion resistance for gates where the dimensions permit the galvanization process. These premium corrosion protection options directly extend the service life of the flood gate in the wet, salt-contaminated, and chemically aggressive environments of coastal flood risk zones.
Custom Design to Structural Entrance Conditions
The project-specific design adaptation to the structural condition of each entrance — wall material, threshold level, floor construction, and approach geometry — ensures that the flood gate system integrates with the actual construction of the protected entrance rather than requiring the entrance to be modified to fit a standard gate. This custom adaptation directly enables flood gate installation at any existing entrance without major structural modification.
2-Year Guarantee — Confidence in Quality
The 2-year guarantee on all Madoors USA sliding flood door gate systems provides the installation confidence and procurement assurance required for commercial and institutional flood protection investment — confirming Madoors USA's quality and reliability commitment throughout the full post-installation warranty period.
