Double-Leaf Blast-Resistant Door—Industrial door

Product Features

Our double-leaf explosion-proof door is engineered for maximum protection in hazardous environments. The 70mm-thick door leaf consists of 1.5mm galvanized steel panels on both sides, reinforced with a steel skeleton and honeycomb paper/insulation cotton filling for optimal strength-to-weight ratio. The 180mm-wide door frame is constructed from 2.0mm galvanized cold-rolled steel, featuring an integrated single-seal gasket to prevent gas/dust infiltration.

Key structural elements include:

• Over 50% thick steel pipe reinforcement inside the door leaf.

• 1.0mm galvanized steel outer panels for corrosion resistance.

• Explosion-proof lock system for enhanced security.

Key Advantages

✔ Unmatched Blast Resistance – Withstands ≥69Kpa shockwave pressure, making it ideal for chemical plants, military bunkers, and oil refineries.
✔ Precision Manufacturing – Flatness ≤4mm/m² and tight dimensional tolerances ensure seamless installation.
✔ Durable & Lightweight – Honeycomb paper & insulation cotton filling reduces weight while maintaining structural integrity.
✔ Airtight Protection – Single-seal gasket in the frame prevents hazardous gas leaks.

Applications

These double-leaf blast doors are essential for:

• Oil & Gas Facilities – Secure control rooms & hazardous storage.

• Military & Defense – Protect ammunition depots & command centers.

• Chemical Plants – Isolate explosion-prone zones.

• Power Stations – Shield critical infrastructure.
