Deansteel is a family-owned company that has roots in the sheet metal industry as far back as 1879 when Joseph Dean, Sr. emigrated from Manchester England and settled in San Antonio, Texas. The Deansteel Manufacturing Company as it is known today was founded by Albert Dean, Jr. , grandson of Joseph Dean. After Albert Dean returned from serving in the Navy during World War II, he eventually acquired the machine shop that is a part of their present location on South Flores Street. Deansteel started out making doors and frames, and in 1948, their first job was to make all the doors and frames for the Laredo, Texas hospital.
Since 1948, Deansteel’s product lines have expanded to include doors and windows for commercial, marine, self-service storage, and security applications, as well as marine furniture and interior wall systems. Deansteel today has some of the most modern equipment for precision sheet metal fabrication in their production facility that covers over 100,000 square feet. Deansteel has grown to have customers world-wide, yet retains that family-owned, “small business” way of working with their customers. A personal commitment to quality throughout the company, plus keen financial planning, and continually looking for ways to innovate in current operations and new product lines, ensures Deansteel’s continued growth. Deansteel is taking the steps to make sure they will be there in the future to stand behind the products you buy today.
Deansteel started serving the marine and offshore industry in 1969 building joiner doors. The product line has expanded to include a full line of USCG CFR-46 and IMO-FTP Code marine fire resistant doors, frames, and windows; as well as all steel berths and marine furniture. This line of joiner door units and windows is certified by the USCG and Lloyd’s Registry. Since all of these items are made in the United States, they fully comply with the Jones Act. Deansteel is the only manufacturer in the United States of marine fire-rated doors, frames, windows, steel berths, and marine furniture with current testing and certification for all of their products.
Deansteel has long been known in the marine and offshore industry for top quality construction, durable products, and dependable delivery, all at competitive pricing.

For more than 50 years Deansteel Manufacturing has been a leading supplier of high quality commercial hollow metal doors and frames for all commercial applications. These products conform to the industry standards set forth by the Steel Door Institute. Deansteel carries an extensive inventory of standard sizes and configurations of their hollow metal doors, getting you the door you need as soon as you need it.
Deansteel standard hollow metal doors are made of 16, 18 or 20 gauge cold-rolled stretcher level quality steel, and are 1-3/8” or 1-3/4” thick with a polystyrene slab core. Door skins are welded to 16 gauge perimeter channels. Hinge reinforcements, closer reinforcements, and internal lock reinforcements come standard on all hollow metal doors. All Deansteel doors have square edges, and are non-handed. Handing is accomplished with hinge filler plates. Each door is finished by thoroughly cleaning and phosphatizing to inhibit corrosion and increase paint adherence, with a single coat of primer for further protection from corrosion and a base for painting. Doors are available in all popular standard widths and heights.
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.They 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.
Deansteel 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.
DEANSTEEL SECURITY DOOR PRODUCTS AND WINDOWS UNDERGO EXTENSIVE TESTING
Deansteel blast-resistant door, frame and window designs are tested and analyzed by independent, internationally recognized engineering laboratories to assess their performance. 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.
