The Blast resistant doors Doors or Blast proof door is designed in order to protect the nearby areas in case of fire / Blast in Compressor/transformer/Boiler/Explosion and for Military use. Doors are single or double-winged to stop the advance of blast waves into the protected area. Blast resistant doors protect people and property from explosions and shrapnel.

Blast resistant doors are designed to support the overpressure caused by an explosion of equipment. Also, the Explosion resistance doors can be designed for a lifelong. Blast load resistance of up to 40 bar peak reflected overpressure and up to 180 minutes( 3 Hours) fire rating confirming to BS 476 part 20 and 22. The sizes of the door can be up to 4m x 6m (WxH) or as per requirement and the same can be either manually or automatically operated with the help of Pneumatic/ Hydraulic/ Electric mechanisms.

The door plate or frame assembly has an optimized pattern for the transfer of the blast forces into the surrounding wall. The blast doors are provided with suitable single/multiple gaskets for airtightness as per specifications.

Due to the unique nature of some projects, a pre-engineered model is not always the best selection. Often, a custom design is required. That is where we come in. Our engineering and sales staff can help custom design a product to meet your most demanding applications.

Blast Proof Doors/Blast Resistant Doors are designed to protect human life from any accidental explosion that may occur at petrochemical plants or industrial manufacturing facilities. They offer disaster prevention and protection for main facilities and effectively manage and control explosions resulting from experiments at military facilities or at laboratories where this risk exists. As the largest steel doors manufacturers in India, we are unsurpassed on both the quality and effectiveness of our blast proof doors.

ESEW provides blast proof doors used in high-security areas such as strong rooms, battery rooms, and transformer rooms, Military control rooms, Aircraft hanger and many more.

ESEW is the only company that provides contemporary blast doors.


  • Military Bunkers
  • Ammunition Bunkers
  • Missile Test and Launch Sites
  • Chemical and Hazardous Material Storage Rooms
  • Nuclear Power Stations
  • Petrochemical and Industrial Complexes

  • Pharmaceutical Facilities and University Laboratories

Due to the unique nature of some projects, our design team can create a specific blast door to suit the requirements of each situation. These doors can be made to offer electromagnetic pulse protection (EMP), ionizing radiation shielding, and to shield against conventional explosives and gas infiltration.

Our products assure the highest level of blast protection under critical conditions for both exterior and interior environments. In addition to Blast Resistant Doors, ESEW also design and manufacture a wide range of pre-engineered or tailor made Blast Resistant Valves.



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.


ESEW Products offer a complete or supervised installation service for all of our doors.
