Type B Blast Door

The Type B Blast Door is an enhanced blast-resistant door for high-risk facilities. It offers stronger blast protection than the Type A. This door is designed for large petrochemical plants, fine chemical workshops, high-explosive warehouses, and military ammunition depots. The door uses thicker, high-strength steel. The frame is made from heavy rolled steel. The door body has reinforced multi-layers. These include thicker blast-resistant steel, enhanced impact-resistant, and reinforced fire layers. The door stops stronger blasts, fire, impacts, and flying debris. The gap between the door and frame is less than 1mm. The Type B Blast Door can handle higher level explosion shock waves.

This Type B Blast Door is built for the highest risk environments. Large petrochemical plants use it for their main facilities. Fine chemical workshops use it for their production areas. High-explosive warehouses use it for their storage. Military ammunition depots use it for their bunkers. High-risk laboratories use it for their test areas. The door has heavy hinges and reinforced bolts. These keep the door in place during an explosion. The door structure is specially designed to spread and absorb blast energy. The door comes with heavy mechanical locks and emergency escape devices as standard. You can add fire locks, electronic locks, and fingerprint systems. The door works with both concrete and steel frame buildings. We can customize the size to fit your opening.
