AISC certified manufacturing
New Millennium manufactures FreeSpan
™
castellated and cellular beams right
here in the USA at our production facility in Continental, Ohio.
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.

Castellated and Cellular Beams
Freedom of design
FreeSpan
™
castellated and cellular beams bring you
more options for greater structural design freedom and the
means to increase project performance, while reducing
project costs.
In addition, the beam is more space-efficient and cost-efficient
than concrete, making it possible to design wider bays with
refreshingly creative form and function at lower costs.
For parking garages, hospitals and most any project where
space is at a premium, the beam offers a structurally lean
and low profile with an open, airy, and aesthetic appeal.
Freedom of choice
The versatility of FreeSpan
™
beams is demonstrated by its
use across an extremely wide spectrum of building types,
sizes and specialized functions.
In addition to the aesthetic appeal, the strength of the
beam can be precisely matched to the load for greater
cost efficiency. FreeSpan
™
is readily available with either
hexagonal or round openings, and their varying lengths
can be erected to create arches, columns, and other artful
yet structural elements.
Freedom for all
Architects now have the means to create better-designed
spaces. Structural engineers now have the means to reduce
or eliminate traditionally accepted project costs. Erectors
find that FreeSpan
™
beams erect faster than concrete and
more easily. And there are far fewer impediments to the
trade professionals who integrate the mechanical, electrical,
plumbing and fire suppression systems.
Project owners benefit from buildings that perform with
greater space efficiency, unfettered by cost and perfor-
mance limitations imposed by other construction methods.

How to Specify
How to Specify
When a wide-flange beam is castellated with a standard
hole pattern, the section depth increases by approximately
50%. For example a W12x14 beam at 12 inch nominal
depth expands to 18 inch nominal depth when castellated.
The resulting castellated beam section is designated a
CB18x14, where:
CB = Castellated Beam (LB for Cellular Beam)
18 = Nominal Depth in inches (1.5 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. Beams
with hexagonal web openings are called castellated
beams and designated with a CB, whereas beams with
round web openings are called cellular beams and
designated with an LB. The difference in web opening
shape is primarily for architectural purposes. However,
for projects using a galvanized finish, New Millennium
recommends the use of cellular beams in order to minimize
stress risers in the galvanizing process.
The web opening pattern may vary depending on span,
end connections, load requirements, or hole alignment to
adjacent beams. So, it is important that New Millennium
be informed of the loading condition under which the
beam is intended to be used. Unless otherwise noted
on the contract structural drawings, New Millennium will
assume the beam to have a uniformly distributed design
loading. Beam design loads other than uniformly distributed
must be specified either on the framing plan or in a
loading diagram.
Any other special requirements, such as duct passage
or special castellation geometry, must also be clearly
noted on the drawings.
Hybrid FreeSpan
™
beams may be constructed of two
different beam sizes, combining a lighter upper half beam
with a heavier lower half beam, provided that both beams
are the same nominal depth, and the web thicknesses do
not differ by more than 3/16”. Hybrid FreeSpan
™
beams
are commonly used in composite construction, where the
concrete slab acts as a large top flange. CB18x14/26
is an example of an asymmetric FreeSpan
™
beam
designation, where:
CB = Castellated Beam (LB for Cellular Beam)
18 = Nominal Depth in inches (1.5 times the nominal
wide flange depth)
14 = Nominal weight per foot of top beam half (plf)
26 = Nominal weight per foot of bottom beam half (plf)

How to Specify
Finish
FreeSpan
™
castellated and cellular beams can be
furnished with a shop provisional coating. The shop
coating is intended to provide temporary protection to the
steel beams during delivery, storage on site, and erection
in an atmosphere comparable with SSPC Environmental
Zone 1, normally dry. The primer conforms to both SSPC
15, Type 1 (gray) and Federal Specification TT-P-31 (gray),
with minimum 1.0 mils dry film thickness.
FreeSpan
™
beams can be furnished with a galvanized
finish. When using a galvanized finish, it is important to
minimize stress risers such as abrupt changes in cross
section. For this reason, we recommend the use of
cellular beams rather than castellated for use with
galvanized finishes.
Welding
All welding procedures and welders are certified in
accordance with AWSD1.1.
Deflection and Camber
FreeSpan
™
castellated and cellular beam deflection is
calculated using simple beam theory, with I
effective
= 0.9 I
x_net
.
If camber is required, it is the responsibility of the designer
to indicate the camber requirements on the contract framing
plan. FreeSpan
™
beams have the advantage of inexpensive
cambering during the manufacturing process.
Floor Vibration
Floor vibration characteristics may be checked following
the same procedure used for wide-flange beams, as
discussed in the American Institute of Steel Construction
Design Guide 11, Floor Vibrations Due to Human Activity.
Due to their high stiffness-to-weight ratio, FreeSpan
™
castellated and cellular beams are often preferred for
use in vibration sensitive applications.
Materials
Steel used to manufacture FreeSpan
™
castellated and
cellular beams conforms to ASTM A572/A572M,
A529-50, or A992-50. For other material specifications,
contact New Millennium for availability.

Design
FreeSpan
™
castellated and cellular beams are designed
in accordance with the American Institute of Steel
Construction (AISC) Specification for Structural Steel
Buildings, 14th Edition, ANSI/AISC 360-10.
FreeSpan
™
castellated and cellular beams are designed
similar to Vierendeel trusses. The design approach is based
on the procedure outlined in Book of Welded Structures, by
Omar Blodgett, and includes the following checks:
Overall Bending
Appropriate checks are made for the overall beam stability
and flexural strength, as a function of lateral bracing and
effective unbraced length.
Shear
Three potential shear limit states are checked
for FreeSpan
™
beams:
1. Vertical shear thru the gross section at a web post
2. Vertical shear through top and bottom T-sections at
a web opening
3. Horizontal shear at the web post and weld
T-Section Flexural Stresses
Similar to a Vierendeel truss, the transfer of vertical shear
across the web openings results in local bending stresses
within the top and bottom T-sections. This local bending
stress must be considered in combination with the tension
and compression resulting from the overall beam flexural
stresses, as well as the shear stresses.
Web Post Buckling
The FreeSpan
™
web posts are subjected to a variety of
stresses. Just as with the T-Sections at web openings, the
web posts are subjected to flexural stresses resulting from
shear transfer, in addition to vertical and horizontal shear,
as well as compression due to loads applied to the top
flange. Web post buckling strength is checked based
on research performed by Dr. Richard Redwood of
McGill University.
7
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. Care
should be taken to avoid damaging beams during
handling and erection.
For FreeSpan
™
beams shown with bridging requirements,
the center row of bridging must be in place prior to re-
leasing hoisting cables. After the center bridging row is
in place, only one person is permitted on the FreeSpan
™
beam, until all other required bridging rows are installed.
Bridging requirements for common FreeSpan
™
beam sizes
and spans are shown in the FreeSpan
™
Castellated and
Cellular Beam Section Property Tables. The bridging
requirements shown are based on a maximum construction
load of a 4000 lb deck bundle equally supported across
a minimum of three FreeSpan
™
beams, plus two employees.
The deck bundle is assumed to be either spread along a
3 foot portion of the beam no more than one foot from the
support at one end, or uniformly distributed along the
beam span. Bridging requirements were calculated based
on beam spans up to a maximum of 90 feet in length.
The instructions and the tabulated bridging requirements
are based on typical conditions and common construction
loading. If unusual conditions or loads are present or
anticipated, or for spans in excess of 90 feet, please
contact New Millennium Building Systems, LLC.

BIM Design Collaboration
We participate in BIM-based projects using our industry-leading
Dynamic Joist
®
digital design component. The component is
available as a free, downloadable add-on for Tekla Structures.
Additional components are in development at New Millennium
to support our many product lines and for use with other digital
software provider formats.
Standard Steel Joists
Joist products include K, LH and DLH Series joists and joist
girders, and CJ Series joists (Composite Joist). Joists can be
furnished as a single-piece up to 15 feet deep and 125 feet
long. All are produced in accordance with the specifications
of the Steel Joist Institute.
Flex-Joist
™
Gravity Overload Safety System
New Millennium’s Flex-Joist
™
is uniquely designed to flex prior
to collapse under extreme gravity overload conditions. The slow
stretching of steel in tension leads to large inelastic deflections
and results in a slower collapse, adding crucial time for
emergency response. We achieve this ductile behavior by
limiting component relative strength ratios such that a primary
tension member is the weakest steel joist component. The
Flex-Joist
™
design improves steel joist reliability and increases
the probability of safe evacuations while generally decreasing
the probability of a collapse.
Special Profile Steel Joists
Unique roofline designs are now practical and economical
using special profile steel joists, due to our development of
engineering specifications enabling over 40,000 special profile
steel joist design possibilities. We manufacture a complete
range of special profile steel joist products, including bowstring,
arched, scissor, double-pitched, and single-pitched joists.
Steel Roof and Floor Decking
Metal deck options include roof deck, form deck and composite
deck. Engineered to the application, our steel decking systems
are certified to address performance requirements related to
such factors as wind uplift, fire resistance and noise reduction.
Assure the winning success of your project, with our full range
of structural steel roofing and flooring systems:
