Hinged Flood Barrier Systems
The High Floodwater Door BL/HHS — a horizontal swivel system for permanent, architectural flood protection.
PERMANENT FLOOD DOOR SYSTEMS
The BL/HHS flood door is designed for both new buildings and existing facilities and is suitable for retrofitting. The system comprises a very robust and durable door leaf supported by a heavy-duty frame, and a peripheral stainless steel frame construction with a durable, adaptable UV-protected seal.
The door leaf is mounted on hinges and easily closes and locks through a 3-point lever mounted on the door. Operation — opening and closing — is similar to a standard door.
Regardless of side mounted, the systems can accommodate water pressure from both sides.
Easy Operation
Opens and closes like a standard door. A 3-point lever mounted on the door provides quick locking by hand.
Bidirectional Protection
Designed to accommodate water pressure from both sides — fully reliable regardless of flood direction.
Premium Materials
Aluminum door leaf and stainless steel frame. Special powder-coated designs available in any RAL spec.
