The door is made by steel door frame and door leaf filled with rock wool insulation materials, which has the function of flame retardant and heat insulation.

The explosion pressure value of the explosion venting door can be controlled by the bolt.

Once the explosion pressure reaches the design value, the venting door will open on its own, so as to achieve the effect of pressure relief when blast happen. After the explosion, the door can be used again after simple treatment.

Good thermal insulation,good tightness, good wind resistance,good sound insulation and good anti-theft performance.
