Fire Resistance Bulletin #1
This Bulletin provides a detailed discussion on fire endurance of welded built-up steel columns, cold formed channel columns and steel pipe columns. These columns have been UL tested and certified for 1, 1.5 and 2 hour fire protection.
Fire Resistance Bulletin #2
This Bulletin provides a detailed discussion on the results of an engineering analysis and testing program, which sought to establish fire resistant rated exterior walls. These walls are listed by UL, Inc. In the 1996 Fire Resistance Directory as UL Design No. U489. Design configurations and detailed material characteristic data are presented in this highly informative Bulletin.
Fire Resistance Bulletin #3
An MBMA building, equipped with a fire rated roof assembly with a suspended ceiling places the metal building in a totally new class of construction. Find out more about the extensive testing conducted in conjunction with UL, which resulted in a new roof classification for several different types of suspended ceilings.
Fire Resistance Bulletin #4
This bulletin details a new assembly that reduces the extra cost of labor and materials required to build a fire resistant rated exterior wall that is tested by UL and classified for 1-and 2-Hours.
Fire Resistance Bulletin #5
Two new fire resistance rated wall assemblies were successfully developed and tested at Underwriters Laboratories, Inc. (UL) by MBMA. These two assemblies, known as UL W404 and UL W413, contain several prominent attributes. Both designs preserve the most common and efficient metal building system construction practices of the industry and provide for 1-hour and 2-hour non-loadbearing wall systems.
