Product Advantages
Four-Layer Composite Safety Structure

Structural Composition:
100mm all-steel main framework
5mm high-strength steel plate layer
Professional waterproofing layer
Fire-resistant and thermal insulation layer

The synergistic effect of these multiple layers ensures a high level of safety protection.
Impact Resistance
The high-strength steel framework effectively absorbs and disperses external impact loads, enhancing overall structural stability.

Explosion Protection
Utilizing a specialized explosion-proof design combined with an overpressure relief valve system, it effectively mitigates the impact of explosive shockwaves.

Fire Resistance
The fire-resistant layer effectively delays the intrusion of high heat and enhances the structure's fire endurance, buying valuable time for personnel evacuation and sheltering.

Waterproofing and Sealing
The integrated structure offers excellent watertightness and airtightness, preventing the ingress of groundwater, hazardous gases, and dust.

NBC Protection
An independent NBC filtration system filters and purifies nuclear, biological, and chemical contaminants, ensuring safe indoor air quality.

Emergency Escape System
Equipped with an independent escape route and ladder to ensure rapid evacuation during emergencies.
