Product Q&A

Q:Is the flood door permanent?

This heavy-duty watertight door is engineered for permanent installation with a design life of 20-40 years. Unlike demountable barriers, it is fixed to the wall and does not require removal after floods.

Q:What materials are used for the door?

The main structure is made of Mild Steel or Stainless Steel sheets, powder coated in fluorocarbon anti-weathering paint. The frame uses T5*100*100 Square Tube, and the gaskets are EPDM.

Q:What are the maximum dimensions?

The height is customized to fit the specific door opening. The width is limited to a maximum of 2000mm for each leaf. Panel thickness is T8mm.

Q:How is the door sealed and operated?
