During the castellated beam production process, a solid steel beam forged from recycled steel is cut in half lengthways, using automated plasma torch cutting. The split halves are then offset and welded back together to create a beam that is the same weight, but is now deeper, stronger, and ideally suited for long span applications. Our highly efficient manufacturing facilities can produce 90-foot castellated beam sections. Customized beams are engineered to address unique project needs, including welded infill sections for special connection points.

Structural engineers now have the means to reduce or eliminate traditionally accepted project costs. Architects now have the means to create better-designed spaces. For parking garages. electrical.Castellated and Cellular Beams Freedom of design Freedom for all FreeSpan™ castellated and cellular beams bring you more options for greater structural design freedom and the means to increase project performance. sizes and specialized functions. hospitals and most any project where space is at a premium. Freedom of choice • 50% deeper with depths up to 66 inches The versatility of FreeSpan™ beams is demonstrated by its use across an extremely wide spectrum of building types. columns. And there are far fewer impediments to the trade professionals who integrate the mechanical. the beam offers a structurally lean and low profile with an open. and other artful yet structural elements. making it possible to design wider bays with refreshingly creative form and function at lower costs. and their varying lengths can be erected to create arches. recycled steel • Lower floor-to-floor height with integrated MEP runs • Beams erect faster due to fewer columns • Low floor vibration is characteristic of the beam • Open access for future owner maintenance 3 . Erectors find that FreeSpan™ beams erect faster than concrete and more easily. FreeSpan™ is readily available with either hexagonal or round openings. the strength of the beam can be precisely matched to the load for greater cost efficiency. while reducing project costs. unfettered by cost and performance limitations imposed by other construction methods.S. In addition. plumbing and fire suppression systems. the beam is more space-efficient and cost-efficient than concrete. Beams with hexagonal web openings are called castellated beams and designated with a CB. plf Z = 26 lbs. such as duct passage or special castellation geometry. For example a W12x14 beam at 12 inch nominal depth expands to 18 inch nominal depth when castellated. The web opening pattern may vary depending on span. Unless otherwise noted on the contract structural drawings. New Millennium will assume the beam to have a uniformly distributed design loading. end connections. plf X = 18” beam depth CB18x14 Y = 14 lbs. whereas beams with round web openings are called cellular beams and designated with an LB. Beam design loads other than uniformly distributed must be specified either on the framing plan or in a loading diagram.5 times the nominal wide-flange depth) 14 = Nominal weight per foot (plf) FreeSpan™ beams may be manufactured with either hexagonal web openings or round web openings. it is important that New Millennium be informed of the loading condition under which the Hybrid FreeSpan™ beams may be constructed of two different beam sizes. or hole alignment to adjacent beams. where: CB = Castellated Beam (LB for Cellular Beam) 18 = Nominal Depth in inches (1. for projects using a galvanized finish. where: beam is intended to be used.

Just as with the T-Sections at web openings. as a function of lateral bracing and effective unbraced length. 14th Edition. the transfer of vertical shear across the web openings results in local bending stresses within the top and bottom T-sections.

Vertical shear thru the gross section at a web post 2. the web posts are subjected to flexural stresses resulting from shear transfer. and includes the following checks: Overall Bending Appropriate checks are made for the overall beam stability and flexural strength. Shear Three potential shear limit states are checked for FreeSpan™ beams: 1. in addition to vertical and horizontal shear. If unusual conditions or loads are present or anticipated. Bridging requirements were calculated based on beam spans up to a maximum of 90 feet in length. or uniformly distributed along the beam span. After the center bridging row is in place. Bridging requirements for common FreeSpan™ beam sizes and spans are shown in the FreeSpan™ Castellated and Cellular Beam Section Property Tables. please contact New Millennium Building Systems. Care should be taken to avoid damaging beams during handling and erection. plus two employees. the center row of bridging must be in place prior to releasing hoisting cables. LLC.Handling and Erection FreeSpan™ castellated and cellular beams are to be handled by attaching cables through the web holes at approximately 1/3 points of the beam span. until all other required bridging rows are installed. support at one end.

For FreeSpan™ beams shown with bridging requirements. The instructions and the tabulated bridging requirements are based on typical conditions and common construction loading.
