Blast Rated Swing Door

NAFFCO blast doors are designed to block the advance of air blasts waves through passageways into protected areas in blast-hardened civil defense, military shelters & Petrochemicals areas. Doors are made of structural steel with solid homogeneous steel plates and can open and close manually or motorized. Customized flush design of frames allows for easy installation into reinforced concrete walls, and the door plate/frame assembly is formed from an optimized pattern that transfers any blast force to surrounding walls.

NAFFCO Doors are designed to withstand long duration blast loads having a reflected loading pressure of 1.0PSI to 20Bar especially for commercial, Government, industrial & military applications to protect human life and proprieties from explosions.
