Practice Specifications Weight Tables Weight TablesJoist ASDLoad TablesJoist LRFDLoad TablesFlex-Joist tension controlled steel joist design results in a joist thatcharacteristically displays both higher strength levels and largeinelastic deformations prior to collapse. The result is a roof or floorframing system with improved strength, an improved reliability index,and improved sensory alert to overload prior to collapse.Flex-Joist tension-controlled steel joist design is ideally suited toelectronic monitoring of deflection and/or strain for early warningof high loads, if desired. This can allow time for building evacuation,load removal, and/or shoring to prevent collapse. Although electronic monitoring is not provided by NMBS, we can help coordinaterequirements with your electronic monitoring supplier.SPECIAL PROFILE STEEL JOISTSUnique roofline designs are now practical and economical usingspecial profile steel joists, due to our development of engineeringspecifications enabling over 40,000 special profile steel joist designpossibilities. We manufacture a complete range of special profilesteel joist products, including bowstring, arched, scissor, doublepitched, and single-pitched steel joists.METAL DECKINGRoof and floor metal deck options include B deck, N deck,form deck and composite deck. Engineered to the application,our decking systems are certified to address performancerequirements related to such factors as wind uplift, fire resistanceand noise reduction.4Discover the easiest way to specify steel joists and Joist Girders:www.newmill.com/digital-tools
