Performance characteristics of tunnel protective doors: The protective doors are lightweight, easy to open and close, and can meet the lightweight load requirements of the project, while also having a good fire prevention effect;

The design concept of tunnel protective doors is to resist the air pressure brought by trains traveling in the tunnel, so that the internal equipment is intact and not affected by air pressure shock waves.

Tunnel protective door:

A metal door that can resist gas shock waves generated when an explosion occurs under certain conditions;

Tunnel protection door protection level:

Under the specified testing conditions, classify the levels based on the release of gas shock waves from tunnel protection doors;

Design capability of tunnel protection door: The tunnel protection door system has superior explosion-proof performance, with a blast resistance of 0.11Mpa (110Kpa); Through multiple internationally recognized certifications and tests; The system is designed to operate flexibly and reliably, with both fire resistance and explosion resistance.
