Large access openings in civil defence shelters, protected industrial facilities, ammunition storage sites and other critical infrastructure require specialized protective systems capable of maintaining the structural integrity of the facility during extreme events. Sliding Blast Resistant Gates developed by Atmas Group are engineered specifically for these demanding applications.

According to the manufacturer, these gates combine a reinforced sliding leaf, multipoint locking system and heavy-duty rail mechanism to provide protection against blast loads while allowing efficient operation for large openings.


Purpose and Applications

Sliding Blast Resistant Gates are designed for installation in:

  • Civil defence shelters

  • Bunkers

  • Safe rooms

  • Industrial protected facilities

  • Ammunition storage facilities

  • Other protected infrastructure

According to Atmas Group, these gates are engineered to withstand:

  • High dynamic blast pressure

  • Static blast pressure

  • Ground shock pressure

The manufacturer also states that the design can provide additional protection against:

  • Ballistic threats

  • Forced entry

  • Fire


Sliding Mechanism

Unlike traditional hinged blast doors, these protective gates operate using a sliding rail mechanism that moves the reinforced leaf horizontally.

The system consists of:

  • Reinforced gate leaf

  • Sliding rail mechanism

  • Multipoint locking mechanism

  • Heavy-duty support structure

This design allows very large openings to be protected while reducing the space required for operation, making sliding gates suitable for industrial entrances and oversized shelter access points.


Construction Materials

According to Atmas Group, Sliding Blast Resistant Gates can be manufactured using:

  • Structural steel

  • Stainless steel

  • Composite materials

The manufacturer also notes that additional protection may be achieved through the use of:

  • Concrete inserts

  • Other engineered material inserts

This flexibility allows the gate configuration to be adapted to specific project requirements.


Main Specifications

The official product page lists the following features:

  • Multi-point locking system

  • Standard or customized dimensions

  • Single-leaf or double-leaf configurations

  • Structural steel, stainless steel or composite construction

  • Optional gas-tight sealing

  • Optional fire resistance

  • Available in manual or motorized versions

These specifications are provided directly by Atmas Group.


Custom Engineering

Atmas Group states that Sliding Blast Resistant Gates are available in both standard and fully customized configurations.

Projects can be tailored according to:

  • Opening dimensions

  • Required protection level

  • Installation conditions

  • Structural design requirements

  • Customer-specific engineering needs

The company also develops integrated protection systems for doors, gates and critical openings in protective structures.


Typical Applications

According to the manufacturer, Sliding Blast Resistant Gates are suitable for:

  • Civil defence infrastructure

  • Protective shelters

  • Military and security facilities

  • Industrial plants

  • Energy facilities

  • Critical infrastructure

  • Ammunition storage facilities

  • Secure storage buildings

  • Safe rooms

Their sliding design makes them particularly suitable for protecting large openings where conventional swing doors are impractical.


Conclusion

Sliding Blast Resistant Gates by Atmas Group are engineered protective systems intended for large protected openings in shelters, bunkers and industrial facilities. According to the manufacturer, the gates combine reinforced construction, sliding rail technology and multipoint locking while offering optional gas-tight sealing, fire resistance and manual or motorized operation. They can also be manufactured in customized sizes and configurations to meet project-specific requirements.
