Ordinary metal KD flood doors are suitable for installation in buildings where there is a possibility of flooding. The doors can ensure a perfect water seal up to a height of 2.5 m as long as they are installed in a watertight wall. The doors are completely flood-proof.

Installation

The installation of the frame of a KD flood door must be performed in conjunction with the construction, i.e. the concreting of the wall. The frame of the door must be covered in watertight concrete.

Special feature

Ordinary KD flood doors have a minimum height threshold of 30 mm from the finished floor, in order to ensure sealing. When a risk of flooding has been announced, the doors must be closed manually.

The door and the frame are manufactured from a solid steel construction. The door can also be manufactured from stainless steel.

The door is fitted with an EPDM foam seal, which ensures long-term reliable sealing.

Seal properties

• exceptional sealing properties in extreme weather conditions and an excellent temperature stability (from −40 °C to +150 °C) in cold climatic conditions;
• compared with seals from other materials, it is very resistant to wear, ageing, weather, ozone, and UV.

Protection

The doors are double powder-coated, which ensures a total coating of 120 microns. The colour can be selected from the RAL colour chart.

The doors have class C3 corrosion protection in accordance with DIN55633 and EN ISO 12944 standards.

Door dimensions

The doors are opened and closed manually.
