Screen Doors

Paras Defence is the undisputed market leader in Shielded Doors, where we produce a large number of doors every year for various Electromagnetic Shielding applications. Shielded Door(s) becomes the most critical Point-Of-Entry (PoE) in any installation, as the door is opened multiple times & each time it is closed, it is required to offer the same Shielding Performance.

Applications :

Offer exceptional Shielding performance along with ease of operation & high durability.
Special Engineering focus is made during the design and manufacturing of Shielded doors, as they are the most critical Point-of-Entry due to their frequent usage.
The heavy-duty cam latch strikes for two-point latching.
The rugged construction of the door is suitable for Naval & Heavy Industry applications.
Fire classification can be offered as an optional requirement.
Single finger strip door (finger strip door with soldered or clamped fingers)
Offer heavy-duty cam latch strikes for two-point latching & clip-in-place Beryllium Copper finger stock.
