One-stop for hollow metal door and frame solutions

Architects, specifiers and other building professionals have a valuable source
of experience and technical information about hollow metal doors and frames.
Since 1969, the Hollow Metal Manufacturers Association, or HMMA, a division of
the Glen Ellyn, Ill.-based National Association of Architectural Metal
Manufacturers, has been a leader in developing performance standards and
specifications, creating and testing hollow metal products, and getting
valuable technical information into the hands of building professionals. HMMA
offers architects and specifiers a one-stop source for technical information.

HMMA members manufacture products designed for varying performance levels up to and including detention security, as well as fire-rated and specialty doors (sound-rated, blast resistant, etc.). Technical data on these products is available in the Hollow Metal Manual, containing 17 standards and specifications, many of which are ANSI accredited. NAAMM is an ANSI-recognized standards development organization.

HMMA recently initiated a series of Technical Notes to address often confusing or problematic aspects of hollow metal doors and frames. These documents have been included in the Hollow Metal Manual and are available as separate documents. Technical publications are being reviewed and updated on a continuing basis, through the efforts of the HMMA Technical Committee.

The complete Hollow Metal Manual includes:

Distribution of Technical Information

Recognizing the importance of getting information into the hands of building professionals, HMMA uses a variety of distribution channels in addition to making the documents available in hard copy and at HMMA's Education and Promotion Committee develops PowerPoint educational modules for use in presentations by the committee or HMMA members at a local level. Currently there are three modules, the Hollow Metal Manual, Fire-Rated Doors and Frames, and Installation and Storage. Local presentations are coordinated as requested. The latter two modules have been accredited by AIA for online CEU credit and may be found through links on the continuing education page of the NAAMM/HMMA Web site.

In September, for the third year in a row, theEducation Committee will conduct educational seminars at the Door and Hardware Institute Show. HMMA uses trade-show appearances to distribute technical information. In addition to DHI, HMMA was present at the AIA Expo in San Francisco and Construct 2009 in Indianapolis.

Leaders in Fire-Rated Assemblies

With roots dating back to the early 1900s, HMMA member firms have been on the leading edge of designing and testing fire-rated doors and frames. HMMA 850 provides a wealth of information about fire-rated assemblies, the testing required, and the labeling of doors and frames. Each specific door and frame construction must be tested and rated to be labeled and used in openings requiring fire-rated assemblies.

In the mid-1980s, HMMA initiated a Joint Test program through which members cooperatively test new and advanced fire-rated assemblies. Testing is conducted through Intertek Testing Services and Underwriters Laboratories, and participating members are able to add successfully rated assemblies to their laboratory follow-up service file.

The Joint Test program is expanding beyond testing of fire doors and frames; HMMA is currently preparing to do windstorm testing in accordance with ANSI A250.13-Windstorm-Resistant Components.
