Leading Blast Resistant Barriers Manufacturer

A blast wall/ blast resistant barrier is a protective barrier designed to mold weakened buildings, equipment or personnel from the influence of especially explosions. These walls help to set fire to blast pressure, flying debris and industrial accidents, terrorist attacks or military functions. They act as the first row of defense, reducing the risk of structural damage and injury in high -risk areas.

Typically, Explosion Resistant Barriers are installed after the construction of the primary structure, especially when a threat is later identified. They are often retrofitted for existing buildings that were not originally designed with blast resistance in mind. The purpose of an explosion resistant barrier is to protect specific aspects or edges of a structure instead of the entire building.

Explosion Walls Applications

Blast walls are versatile and widely used in many areas, including:

  • Industrial Area (Chemical Plant, Oil and Gas Facilities).

  • Military establishment and struggle area.

  • Airport for protecting aircraft and fuel storage.

  • Mining operations, especially during controlled explosions.

  • Construction sites, where planned explosive activity occurs

  • Underground and underwater structures require local protection.

They can also be deployed as temporary safety measures in areas with short -term or changing danger levels.

Choosing to install blast proof barriers for buildings depends on a thorough assessment of the environment and potential hazards. In areas where temporary or localized threats exist, such as explosive materials or short-term operations near potential attack zones, these modular blast barriers may be sufficient. These protective barriers can be combined or deployed strategically to provide multi-directional security when necessary.

OUR PRACTICES

MANUFACTURING OF DOORS

Blast Doors are constructed using steel box section and steel sheet which is fully welded as per the design specification.
The frame is designed for casting into the door opening.
It is recommended that blast door frames are cast into the building fabric. This provides a stronger mounting and
means no drilling, or unnecessary penetrations through the host building wall around the opening.

INSTALLATION OF DOORS

SomNandi Industries products offer a complete or supervised installation service for all of our doors.

STANDARD SPECIFICATION OF DOOR

Blast Resistant Doors are to be designed to resist the effects of a cased 500lb
