High Range Armor Steel Plate Doors
LB Steel’s in-house division – Protective Door Industries (PDI) high range armor steel plate doors are custom engineered for blast or tornado produced missiles or extreme pressure resistance that require high dynamic factors and rebound loading design. The units can be concrete filled for improved radiation shielding, sound reduction or temperature insulating capacity. Our computer generated designs afford maximum protection to withstand forces up to 1000 PSI or even higher. Construction is solid steel plate or composite structural steel and plate combination depending upon design load and size. Careful attention to the design of the hinging, latching and operating hardware assure ease of operation, minimum maintenance and maximum security. The units are fabricated per procedures outlined in the American Welding Society AWS Structural Welding Code for Steel and designs comply with AISC specifications and UFC 3-340-02, “Structures to Resist the Effects of Accidental Explosions”.
