Material & Manufacturing Process
- Panel & Frame Material: The door leaf is made of 1.5-3mm thick high-strength carbon steel / galvanized steel plate, and the door frame is made of 1.5-3mm thick reinforced steel plate. The door body is equipped with multiple sets of reinforced steel ribs, with 5mm thick steel plate reinforcement at the hinge, lock and stress points, to ensure structural stability under high blast impact.
- Anti-Blast Structure: The interior of the door body is equipped with a multi-layer anti-blast reinforced skeleton, combined with high-strength filling materials, which can effectively absorb and disperse explosion shock waves, preventing the door from being deformed or broken under high pressure.
- Sealing System: The door leaf and frame are equipped with high-temperature, high-pressure resistant sealing strips, which can maintain tight sealing under explosion impact, effectively blocking the spread of flames, smoke and toxic gases.
- Welding & Processing Technology: The door body adopts full penetration welding technology, with 100% non-destructive testing (NDT) for all welds to ensure no welding defects. The surface is treated with hot-dip galvanizing + high-temperature powder spraying, with excellent anti-corrosion, anti-rust and anti-salt spray performance, adapting to harsh industrial environments in the Middle East.
- Hardware Configuration: Equipped with dedicated anti-blast heavy-duty hinges (rated for over 100,000 opening/closing cycles) and explosion-proof safety locks, which can withstand high impact without deformation or failure.
- Quality Testing: Each door undergoes strict pressure resistance testing, impact testing and sealing testing before leaving the factory, ensuring that the product meets the specified anti-blast pressure requirements.
Product Advantages
- Reliable Anti-Blast Performance: The heavy-duty reinforced structure and multi-layer anti-blast design can effectively withstand the impact of explosion shock waves, providing reliable protection for personnel and equipment in hazardous environments.
- High Durability & Strength: Thickened high-strength steel plate and full penetration welding process ensure excellent structural strength, impact resistance and deformation resistance, suitable for long-term use in high-risk industrial scenarios.
- Excellent Corrosion Resistance: The hot-dip galvanizing + powder spraying surface treatment provides strong anti-corrosion, anti-rust and anti-salt spray performance, adapting to the high-temperature, dry and corrosive climate of the Middle East, with a service life of more than 10 years.
