Deansteel Manufacturing Compnay
60 Years - 1958 to 2018

Deansteel Manufacturing fabricates a complete line of independently tested and analyzed door, frame and fixed window products to withstand a wide variety of ballistic and blast threats.  We also offer a wide variety of custom fabricated ballistic resistant products such as transaction windows with deal trays, package passers, and return fire, opening windows.

Our various ballistic resistant door and window designs have been tested to withstand all ballistic threat levels set forth by Underwriters Laboratory UL-752 Ballistic Standards, U.S. Department of Justice, National Institute of Justice NIJ 0108.01 Standard for Ballistic Resistant Protective Materials, and the American Society for Testing and Materials ASTM F-1233 Standard Test Method for Security Glazing Materials and Systems.

Our blast resistant door, frame and window designs are tested and analyzed by independent, internationally recognized engineering laboratories to assess their performance against a wide range of blast events.  A large number of full sized door assemblies of different designs have been tested in the shock tube test facilities at Baker Engineering and Risk Consultants (BakerRisk).  The resulting blast exposure and performance data have been analytically modeled to develop blast performance diagrams for different door designs.  This information permits us to provide a spectrum of door assembly designs that can withstand peak blast pressures from very low levels of less than 1, up to a maximum of 50 pounds per square inch (psi) and very long duration blast events.

While most of the time we custom manufacture our ballistic and blast resistant products to meet project requirements and specifications, we also offer a selection of bullet and blast resistant door units as “stock” items in standard sizes.  This inventory allows us to ship directly from our warehouse to you immediately.

Our innovative product line of bullet and blast resistant doors is backed up by Deansteel’s commitment to the highest quality products, attentive customer service, and “small business-style” relationships that have served as the building blocks for this family owned business for over 50 years.
