The Bunker Blast Doors are made of a steel alloy that is very resistant to corrosion. The doors have a thick insulation layer to prevent heat loss and keep the bunker warm in winter. The doors also have a special coating that prevents them from getting damaged by water or any other liquid substances. The Bunker Blast Doors are available in different sizes, shapes and dimensions to suit your requirements. These blast doors can be used for residential and commercial purpose as well.

Blast doors are the main entrance to a bunker. They are designed to withstand the force of an explosion, and keep out the blast wave and flying debris.

The doors may be either hinged or sliding, and may be opened by hand, with a crank handle, or by hydraulic power. They are generally built to resist an explosion of up to overpressure.

The blast door is often a part of a larger system which includes an airlock or an external elevator that allows access to lower levels without exposing the occupants to the outside air. In some cases these doors can be used as an escape route from upper floors in case of fire or other emergencies.

The design is based on the need to prevent gas seepage into a bunker during a chemical or biological attack. The blast door is intended to contain this gas until it disperses on its own or can be removed using ventilation systems within the bunker.[1] The purpose of this design is not only for protection against chemical warfare agents (CWA) but also for protection against toxic industrial materials (TIM).

What is a blast door

A blast door is a type of door that is used in the event of an explosion or other disaster. The purpose of these doors is to protect people from the effects of a blast and to help contain fires, smoke and other contaminants. In some cases, a blast door may be part of an entrance to a bunker or other structure that must remain airtight even when there are explosions outside.

Blast doors can be made from several different materials, including steel and concrete. Steel doors are generally stronger than concrete ones but less likely than those made from reinforced concrete. They also tend to be more fireproof than concrete ones because they don’t get as hot when exposed to flame. In addition, steel doors can be stacked on top of each other so that they don’t take up as much space as concrete ones do when installed in large numbers or in tight spaces such as bunkers or underground shelters.
