Construction Details

Guaranteed Highest Quality...Guaranteed Lowest Price™

Free-standing signs are engineered to survive a 140 mph wind.

Broadway Displays aluminum sign frameAll face-plates, the part of the sign that the display's external LED boards are mounted to, are CAD/CNC (Computer Aided Design/Computer Numerical Controlled) routed from solid aluminum plate, to prevent rusting and increase heat dissipation.

An extensive lattice-formed 3-dimensional aluminum frame is welded to the face-plate to insure rigidity and further aid in heat dissipation.

Aluminum is also used for all exterior surfaces of the sign cabinet, again to prevent future rusting.

Water Exclusion TestAlmost all Chinese-manufactured signs, among others, have steel cabinets and face-plates.

With some manufacturers, incredibly, the face-plate is merely many individual pieces bolted together.  Hardly engineered to withstand 140 mph tornado winds.

Water is the enemy of electronic message centers.  Broadway Digital LED Signs developed a unique cabinet design that channels water and ice away from vital internal electrical components.

The face boards, containing the LEDs, are gasketed and hermetically sealed to prevent moisture from entering the sign through the faces.

EMC under constructionThe interior of the sign incorporates a welded structural-steel frame, necessary for the strength to withstand 140 mph winds.  All other interior metal is aluminum also.

All fasteners are galvanized or non-corrosive; no rust.

Most Chinese displays are painted with questionable paints.  (Remember when the Chinese were caught painting Mattel kid's toys with lead paint?)  Click on our "Paints/Finishes" and "Protective Coatings" tabs on the left to learn how we protect the metals, electronics, and plastics in our signs.  We even add self-cleaning properties.

Quality Certified Signs™ Trained Technicians

Certified Welding

We employ Certified Welders; horizontal, vertical, and overhead.

We are virtually the only sign company in the Dallas/Fort Worth Metroplex employing certified welders.

The Value of Listed Signs

Virtually ALL cities adopt the National Electric Code as law.

The National Electric Code (NEC) requires that for electrical, structural, and installation safety all electrical signs be "Listed" (tested and labelled with an appropriate Listing Mark.)

Certification (testing and labelling) organizations acceptable in the USA to test to the multitude of Standards signs are required to meet are determined by OSHA.

For you the Listing Mark is insurance.  It means that the sign has been tested to insure that it is structurally and electrically safe, and will be installed properly.  You benefit from the knowledge that it is not solely us telling you that our signs are safe, this is what the testing laboratories and the US Government says also.

Will your sign be tested and approved for safe use in a Wet (Outdoor) location? Not if it’s not Listed!

Underwriters Laboratories (“UL” Listing Mark) and Intertek (“ETL” Listing Mark – originally Edison Testing Laboratory founded by Thomas Edison) are the premier certification organizations and 80% of all things electrical are reviewed by them.

UL Listing MarkETL Listing MarkIntertek is over twice the size of UL, and has a greater global presence.  UL is the largest in the USA.  We have both companies test and apply Listing Marks to various signs.

Whether it's channel letters, a wall cabinet sign, a monument sign, pole or pylon signs, electronic message centers, video displays, neon or other electric signs Intertek and Underwriter’s Laboratory pose the toughest design, structural, electrical, and installation standards on the products they approve.

We are the 9th oldest UL Listed Manufacturer in North Texas.  (File #UXYT.E149959)

To see if a manufacturer is a UL Listed electronic sign manufacturer go to http://database.ul.com/cgi-bin/XYV/template/LISEXT/1FRAME/ccnsrch.html and enter "UYFS" in the "UL Category Code" box, replacing "%ccn%".

To see if a manufacturer is an ETL Listed sign manufacturer go to  http://etlwhidirectory.etlsemko.com/WebClients/ITS/DLP/products.nsf/ and enter "UL-48" in the search box.

We are the third oldest ETL Listed sign company in Texas( File #4007685)  (One of the two older companies makes lighted scoreboards, the other makes lighted office door signs.)

There are many sign companies that pretend to be Listed, but are not!

Incidentally, ISO (International Organization of Standardization) Standards, such as ISO 2001, are NOT electrical Listings (similar to a UL or ETL Listing) that allow a sign to be installed.  That said, components in our electronic signs also meet ISO 2001, ISO 9001, ISO 14001 and RoHS standards.

Listing Testing

As a part of UL/ETL product testing, in addition to the evaluations of materials, methods of construction, and how the sign will be installed, the following tests are performed:

  • 24 hour Temperature Rise Test (ANSI/UL 5.2)

  • 24 hour Electrical Usage and Stability (ANSI/UL 5.5)

  • Gasket Aging Test (ANSI/UL 5.7)

  • Gasket Adhesion Test (ANSI/UL 5.8)

  • Exclusion of Water Test (ANSI/UL 5.9)

  • Hi-Pot Test while the Sign is Wet (ANSI/UL 5.3)

  • Bond Impedance (ANSI/UL 5.1)

  • Electronics Input Test (ANSI/UL 8.2)

  • Electronics Humidity Test (ANSI/UL 8.12.1)

To become Listed a sign must Pass every test.

Additional Testing

In addition to the testing required by OSHA, UL and/or Intertek (ETL), Broadway Digital LED Signs™ has reviewed our signs for the following:

  • Hi Temperature Test.  (Mil Std. 883)  Broadway Digital LED Signs™ constructed an "atmosphere chamber" we can place entire signs in and control the environment they operate in.  We have proven the electronics, wiring, and design of our Video Displays and Electronic Message Centers beyond 210°F.

  • Altitude Test.  (Mil Std. 810)  Using another mode of our "atmosphere chamber" we have proven the electronics, wiring, and design of our Video Displays and Electronic Message Centers at an altitude of 18,000 feet - halfway through the earth's atmosphere.  Electricity arcs to grounded objects from much further away in thinner air.

  • Dielectric Voltage Withstand Test.  The electronic components and wiring in every Video Display and Electronic Message Center is "Hi-Pot" tested at 1,200 volts to make sure that the system will not "leak" voltage even under extreme circumstances.

The Electrical Advantage of a “Listed" Sign

Listed Signs Save You Money.

Broadway Digital LED Signs Video Displays and Electronic Message Centers, because they are Listed, are approved to operate with approximately 40% of the power supply requirements of unlisted signs.

This is a huge savings in installation costs, as only 40% of the comparable electrical service needs to be provided.

And since the National Electrical Code limits the branch circuits serving signs to 20 amps maximum, this equates to many fewer circuits.

For safety, an unreviewed sign (not Listed) must be supplied with enough electricity to meet the total “continuous” needs of each internal components rating.  (Each components rating x 125%)

A Listed sign has been inspected as a whole, and the amount of energy actually used has been determined.  The sign is approved for use when supplied with this amount of electricity.

This is always much less than the rating of each internal component taken individually, so the cost of installing electricity to the sign will be significantly less.

Electromagnetic Interference

Radio Frequency (RF) interference from an electronic sign can cause the sign to interfere with radios, cell phones, radar, TV signals, automatic door openers, hospital equipment, etc.

Radio frequency interference can also cause radios, cell phones, radar, automatic door openers, TV signals, hospital equipment, etc. to interfere with an electronic sign.

Although not required in the United States, Broadway Digital LED Signs™ had our electronic signs inspected for Electromagnetic Compatibility (EMC) and Electromagnetic Interference (EMI), even testing beyond the rigorous European standards.

Our non-intrusive circuitry even protects itself, rebooting the sign automatically if an extreme circumstance interferes with our sign.

This assures you of an even-more-trouble-free sign when you purchase from Broadway Digital LED Signs™.
