Proven in heavy typhoon surges and torrential flash floods across urban centers, our automatic hydrodynamic flood gates deploy without electric power, offering unmatched resilience for Milan's subterranean entrances.
The Metropolitan City of Milan (Città Metropolitana di Milano), as northern Italy’s dominant financial and industrial powerhouse, faces severe structural exposure to pluvial and fluvial flood disasters. Nestled in the upper Po Valley basin, the city’s dense urban texture, combined with complex hydrological interactions between the Seveso, Olona, and Lambro rivers, creates an operational landscape where traditional flood defence measures frequently fail.
Over the past three decades, torrential rainfall events in the Alpine foothills rapidly drain into the narrow channels of the Seveso river. As the river reaches northern Milan urban boundaries (Niguarda, Isola, and Porta Nuova districts), subterranean culverts hit dynamic capacity limits. Overflow occurs within minutes, sending millions of cubic meters of mud-laden floodwater into residential basements, commercial car parks, and critical metro transport nodes.
Milan's push toward eco-mobility and urban density has led to multi-tier subterranean development. From multi-story underground garages beneath major commercial centers (CityLife, Porta Nuova) to the rapid expansion of the ATM Metro network (specifically lines M1, M2, M3, M5, and the new M4 connection to Linate Airport), subterranean portals act as natural sumps during cloudburst events. A single breach can cause tens of millions of Euros in structural and electrical damage.
Our proprietary Actual Water Retaining Flood Barrier system operates on fundamental fluid dynamics and buoyancy physics. By eliminating sensors, electric motors, standby UPS batteries, and manual labor, our barriers provide guaranteed, fail-safe water containment during extreme municipal blackouts.
The flood barrier panel rests completely flush with the driveable road surface inside a recessed stainless-steel/aluminum foundation frame. As flash surface water flows down ramps or approaches openings, it drains into the barrier’s inlet basin. No human monitors or water sensors are required.
As water accumulates within the bottom basin, hydrostatic pressure combined with high-density engineered internal buoyancy modules exerts an upward vertical thrust. The main barrier panel pivots automatically around its bottom hinge axis, rising proportionally to the rising flood level.
Once fully erect, the barrier locks into position against side frame pillars. External water pressure forces the perimeter triple-ridge EPDM continuous rubber gaskets against high-precision sealing faces, creating an impenetrable water seal with zero zero-tolerance leakage performance.

Different facilities in the Metropolitan Area of Milan present unique structural interface requirements. Our engineering team custom-fabricates barrier geometry to integrate seamlessly into existing civil works.
Primary Districts: Porta Nuova, CityLife, Corso Buenos Aires, Piazza Duomo Commercial Garages.
Commercial car parks feature steep ramp slopes where surface water cascades down violently during cloudbursts. Our underground garage flood barriers are embedded directly at the threshold of the ramp. Designed with heavy-duty structural A6063-T6 aluminum extrusion panels, they withstand heavy vehicle loads (EU Eurocode 1 axle loadings) during normal traffic hours and rise instantly when water arrives.
Primary Application: Subterranean station portals, ventilation shafts, pedestrian connection channels (M1 Red, M2 Green, M3 Yellow, M4 Blue, M5 Purple lines).
Metropolitan transport tunnels demand maximum reliability. A flood entering an underground station line can paralyze public transport across Lombardy. Our station connection channel barriers install flush into surface entrances, triggering automatically to block water ingress while retaining high structural rigidity against lateral dynamic wave impacts.
Primary Sectors: Enel / A2A Power distribution hubs, telecom exchanges, hyperscale data centers in Rho, Sesto San Giovanni, and San Donato Milanese.
High-voltage transformer rooms and subterranean cable vaults require zero water ingress. Water contact with electrical equipment causes immediate arc flash failures and widespread grid outages. Our substation gate barriers provide continuous perimeter protection, securing critical power assets against extreme pluvial accumulation.
Primary Hubs: Freight terminals around Malpensa Airport corridor, logistics parks in Arese, Segrate, and Monza Brianza.
Large clear-span warehouse gates require wide-leaf modular barriers. Our modular hydrodynamic automatic flood gates can span across driveways exceeding 20 meters without intermediate removable mullions, guaranteeing unobstructed truck access during business operations.
As a premier Chinese flood barrier manufacturer, our direct-from-factory production model empowers Milanese engineering firms, civil contractors, and municipal authorities with high-spec flood defense equipment at highly competitive direct manufacturing costs.
Our manufacturing facility utilizes heavy-duty aluminum extrusion presses capable of producing high-wall-thickness A6063-T6 marine grade aluminum profiles. Stainless steel structural elements use SUS304/SUS316 grade alloys, offering superior resistance against de-icing salts used during Northern Italian winters.
Every barrier leaf is machined on 5-axis CNC routing beds to exact architectural drawings provided by project consultants. Tolerances are held within ±0.5 mm, ensuring perfect field alignment with embedded concrete trenches without structural shimming.
We operate an in-house full-scale hydraulic test basin. Before packing and dispatching orders to Italy, every batch of barriers undergoes static and dynamic water retention testing up to 2.0m head of water, with certified video documentation provided for project sign-offs.
Navigating Italian building codes (NTC 2018 - Norme Tecniche per le Costruzioni) and European civil engineering specifications requires meticulous documentation. Our engineering support desk assists Italian consultants from design phase through field installation verification.
