FE/BR hollow metal construction provides the architect with a great deal of freedom in the design of hollow metal products. The architect can also take advantage of the expertise acquired by those hollow metal manufacturers experienced in FE/BR security work. Over the years NAAMM/HMMA manufacturers have developed advanced methods and equipment enabling them to efficiently manufacture hollow metal assemblies, which address today’s difficult FE/BR security applications. These applications include working with the latest in burglary and bullet resisting hardware and security glazing. A number of these manufacturers offer proven economical and functional designs of FE/BR security hollow metal systems.

EMLA conducted testing on common metal lath and stucco assemblies to provide baseline data to designers, end-users, and standards organizations. The objective of this report is to analyze this data and provide allowable loads for the tested assemblies.

Transverse load tests were performed on 18 stucco wall assemblies with 2.5 (see Report Number L-11-1869a R1) and 3.4 (see Report Number L-11-1869b R1) self-furring expanded metal lath in general accordance with ICC-ES AC191, Acceptance Criteria for Metal Plaster Bases (Lath), effective June, 2009. Both reports present the description of the tests performed, the results of the testing, and the findings. The following EMLA companies participated in the test: Alabama Metal Industries Corp. (AMICO), California Expanded Metal Company (CEMCO) and Clark-Dietrich Building Systems, LLC.
