Nucor Corporation Expands North American
Headquarters with ADC TrueNet
®
Products
SITUATION
Nucor Corporation, the nation’s largest recycler and manufacturer of
steel products, recently expanded its North American Headquarters by
retrofitting an existing 5-story building. With an aggressive short-term
construction schedule, Nucor selects ADC Value Added Reseller (VAR),
Network Cabling Systems for all installation activities and ADC TrueNet
®

copper and fiber products.
SOLUTION
A complete turn-key installation of ADC’s TrueNet copper and fiber
products to each floors Intermediate Distribution Facility (IDF) in Nucor’s
expanded North American headquarters. Also, ADC’S indoor/outdoor
rated fiber products were used to support a remote building and 10
gigabit CopperTen
®
cabling and patch panels within Nucor’s data center
to support active network equipment and servers.
RESULTS
No one understands quality and workmanship of products better
than Nucor Steel. As a leading manufacturer of carbon and alloy steel
products, Nucor wanted a quality and robust technology to serve their
current and future voice and data requirements. “We sought a vendor
that we could work with to do a good and professional installation job,”
explained Dave Dunlap, IT Project lead. “We selected Network Cabling
Systems (NCS) for this project as we already had good past project

experiences with them including our MAC’s (moves, add, changes)
work. We knew their workmanship was quality and their commitment
to Nucor’s standards was on-target with our expectations.” By NCS
introducing us to ADC, we knew we would be getting quality products
and a solid installation. “
CASE STUDY
SITUATION
As a Fortune 500 company, Nucor operates in
nineteen states with its’ corporate headquarters
located in Charlotte, NC. Products produced
are carbon and alloy steel for commercial and
residential use.
Nucor’s success can be attributed to the hard
work and dedication of its employees. Dating
back to 1905, Nucor has always been an
innovator, producing the first commercial cars
with electric lights and electric starters. Known
then as an auto manufacturer, Ransom E.
Olds, founded Oldsmobile and then in 1905,
REO Motor Car Company. Through a series of
acquisitions, the company evolved into the nuclear
instruments and electronics business and later
purchased a company that made steel joists and
joist girders. The company‘s remarkable evolution
led to major innovations in steel manufacturing.
Not long thereafter, in 1972, the company
officially adopted the Nucor Corporation name.
Nucor has expanded its’ operations over the
years and in the summer of 2006, retrofitted
a 5-story building for expansion of its North

American headquarters in Charlotte, NC. It was
an aggressive 6-month construction effort to
completely renovate the existing building. During
this time, Nucor’s IT department led a project to
select a vendor that could deliver professional
results with the installation of the building’s
horizontal and riser cabling infrastructure.
Through a very detailed evaluation, including
presentations from Network Cabling Systems,
all parties agreed that ADC was the solution
that would best fill the requirements Nucor had
determined were essential.
SOLUTION
ADC’s TrueNet Category 6 AirES
®
cable and
modular Category 6 jacks were installed to
each floors’ workstation outlets. Two Category
6 plenum cables were installed to each work
location with each floors’ IDF rooms being
equipped with ADC’s TrueNet patch panels.
For connectivity between each floor’s IDF, ADC
provided a “bundled” Category 6 solution. The
two 6-cable bundled solution contained speed-
wrap and Kevlar for additional strength and
durability and was terminated in each closet on
ADC’s TrueNet patch panels. In each IDF, two
equipment racks were each equipped with ADC
vertical managers, three 8-inch managers for each
rack. Each 8-inch vertical manager was equipped

with removable metal doors. This provided not
only the right aesthetics but also ensured proper
cable management within each IDF.
For vertical riser connectivity between the floors’
IDFs, a 50 micron multi-mode laser optimized
12-fiber ADC cable was installed. The cable with
inter-locking armored sheathing was terminated
on ADC’s TrueNet 2-RU RMG series rack mount
enclosures in each of the floors’ IDFs. “We used
ADC’s RMG’s fiber panels not only in the IDFs but
also in our Data Center and two other additional
locations,” explained Dave Dunlap, Nucor IT
project lead, “as it is a low-profile design that is
modular and flexible for our needs. We chose to
direct terminate in each panel using SC couplers.”
In addition to providing horizontal and vertical
cabling in the new retrofitted building, Nucor also
expanded their network to a remote Generator
building as well as a carrier/rquipment room using
ADC fiber cable. Two 12-fiber multi-mode (MM)
indoor/outdoor plenum rated fibers were installed
in conduit between the Nucor data center
and the generator building and another two
12-stranded MM fiber cable was installed in the
carrier/equipment room. “We needed to provide
connectivity to the generator room for some time
now and additional fiber was needed to expand
carrier services into our data center equipment
distribution area,” explained Dunlap. In both the
ADC's Copper and Fiber cabling running from

the Main Distribution Facility to the Intermediate
Distribution Facilities.
CASE STUDY
carrier room and generator building, a 2-RU ADC
RMG fiber panel was installed originating from
the data center on a 4-RU RMG fiber panel. The
fiber panels contain sliding and removable front
and rear panels which provide convenient access
inside the panel. Up to 72 terminations can be
made in one RU enclosure.
Inside the data center, ADC’s TrueNet 10-gigabit
cabling and 24-port CopperTen 1-RU patch panels
were installed to server cabinets. Each server
cabinet, approximately 15 cabinets total, were
equipped with ADC’s CopperTen 24-port patch
panels. From each server cabinet, ADC CopperTen
cables were extended to a centralized cabinet.
The centralized cabinet, also equipped with
ADC’s CopperTen panels, allows a single point for
moves, add, changes without ever making any
patch changes in the individual server cabinets.
“We wanted an inter-connection between our
switches and servers that would provide us a
single access point for any network changes
required. Now, if we need to make a network
change to any of our servers, we only do it in the
centralized cabinet,” said Dunlap. ADC’s TrueNet
high-performance patch cords were used in the
cabinets as well as the industries only laser-tuned
modular jacks in the patch panels. This ensures

that each jack manufactured is individually
optimized for 10-gigabit performance.
The project also included voice and data
expansion to another floor of the newly
renovated building. Nucor’s affiliate, Castrip,
currently occupies a portion of another floor.
Both fiber and Category 6 “bundled” cables were
extended to this floors IDF originating from the
data center. There were six total bundled cables
each with six Category 6 cables. All cables were
terminated on TrueNet patch panels. The fiber
was a 12-strand MM 50 micron cable with an
armored cable design using an all dielectric central
strength member (CSM).
RESULTS
Nucor Corporation emphasizes one goal, “Take
Care of our Customers.” They are committed to
being the best in their industry by providing the
highest quality products and having the most
productive work-force possible. Their key to being
such a profitable company today is attributed to
working together as a team committed to this
one goal.
Their recent North American headquarters
expansion, allowed ADC and our partner,
Network Cabling Systems, to be a part of their
exciting growth and to work with many talented
Nucor professionals. The challenges were
many and at times, not everything during the
installation went as planned, however, the end

result was a very clean installation and a reliable
network infrastructure that will provide many
years of high-quality and consistent network
performance. “We knew we could count on NCS
to provide a quality installation,” concluded Scott
Messenger, “and we are very happy with all ADC
products that are in our network today.”
