Blast Doors
Blast-Resistant Doors for Shelters, Bunkers & Protected Facilities
Blast doors protect critical entrances and exits against the destructive effects of blast pressure while helping maintain the integrity of shelters and other hardened spaces. Philadelphia Safety Devices offers a range of blast-resistant door systems for civil defense shelters, bunkers, safe rooms, critical infrastructure, and other protected facilities.
Available configurations include single- and double-leaf doors manufactured from steel, concrete, composite, and combined materials. Depending on project requirements, doors can provide blast, fragmentation, ballistic, fire, and gas-tight protection, with options for new construction, retrofit applications, and custom-engineered installations.
