Blast Resistant Doors

PP-PRODUCT PRESENTATION

Pressures above 20 psi are considered High Range Blast (HRB). Overly HRB Doors are custom designed on a job-specific basis and are generally made from varying thickness of monolithic steel plate. These doors are capable of withstanding high momentary explosions and other forces such as explosion-generated fragments and remain operable after the incident. The design of all HRBs are verified by calculations based on Tri-Services Manual TM5-1300, "Structures to Resist the Effects of Accidental Explosions."

Details, performance specifications and FAQ for the HRB line can be obtained from Overly or downloaded from our web site on the Internet.
