Bullet & Blast - About Us
Deansteel Manufacturing fabricates a complete line of independently tested bullet and blast resistant doors, frames, & windows to suit your security needs. Our bullet resistant products have been tested to all threat levels set forth by UL-752, NIJ 0108.01, and ASTM F-1233. While most of the time we custom manufacture these products to meet project requirements, we also offer a number of ballistic and blast resistant door assemblies as “stock” items, allowing us to ship directly from our warehouse to you immediately.
This innovative product line 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.
Our BRP line now includes all of our standard products, such as:

Each product is certified and labeled to withstand the specified threat level by Deansteel based on the testing performed by SwRI©.
Deansteel does not rely on "in-house" calculations to substantiate the design performance of our blast resistant products. All of our Blast Resistant products have been tested and/or analyzed by independent, internationally recognized engineering laboratories to withstand specific levels of blast events. Our blast door assembly designs vary from our DSLB-1 (Deansteel Level Blast 1) providing low-level blast resistance for peak over-pressures in the range of 1 psi up to our DSLB-5 products that provides blast resistance to a peak pressure of up to 50 psi and a moderate duration event. These door assemblies provide blast resistance to meet the requirements specified in ASTM F 2247-11 Standard Test Method for Metal Doors Used in Blast Resistant Applications, UFC 4-010-01 (2012) Dod Minimum Antiterrorism Standards for Buildings, GSA-TS01-2003, or ASCE Design of Blast-Resistant Buildings in Petrochemical Facilities.
Deansteel Manufacturing Company first ventured into the sheet metal business
in 1856 when Joseph
Dean, the great-great uncle of Company owner, John Dean, learned the
craft of sheet metal working as an Indentured Apprentice issued by the
Crown of England. After completing his apprenticeship, Joseph and his
wife immigrated to Texas and set up shop in San Antonio. His primary
business consisted of fabricating common steel household items like pots
and pans, rain gutters, and stove pipes to name a few. The Dean name
quickly earned a reputation throughout South Central Texas as a mark
of quality workmanship.
In the past 55 years, Deansteel has matured from a small sheet metal
shop to a production facility that encompasses more than 138,000 square
feet, and is equipped with some of the most modern fabricating equipment
available. Deansteel maintains a stock inventory of 4,000 doors and more
than 20,000 frame components to supply to our distributors.
