CITY OF CLEVELAND TRAFFIC SIGNAL SUPPORT SPECIFICATIONS
In addition to the requirements of specification, signal supports shall be painted in
accordance with the following:
Powder coating - color: Dark Bronze
Surface preparation - the exterior steel surface shall be blase cleaned to steel structures
painting council surface preparation specification No. 6 (SSPC-SPG) requirements utilizing cast
steel abrasives conforming to the Society of Automotive Engineers (SAE) recommended
practice J827. The blast method used is a recirculating, closed cycle centrifugal wheel system
with abrasive conforming to SAE shot number S280.
Interior coating - interior surfaces (pole shafts only) at the base end for a length of
approximately 2.0 feet shall be mechanically cleaned and coated with a zinc rich epoxy powder.
The coating shall be electrostatically applied and cured in a gas fired convection oven by
heating the steel substrate to a minimum of 350 degrees Fahrenheit and a maximum of 400
degrees Fahrenheit.
Exterior coating - all the exterior surfaces shall be coated with a urethane or triglycidyl
isocyanurate (TGIC) polyester powder to a minimum film thickness of 2.0 mils (0.002"). The
coating shall be electrostatically applied and cured in a gas fired convection oven by heating the
steel substrate to a minimum of 350 degrees Fahrenheit. The thermosetting powder resin shall
provide both intercoat as well as substrate fusion adhesion that meets SA or SB classifications
of ASTM D33S9.
Combination coating galvanized-powder top coat color: Dark Bronze

Surface preparation - prior to being incorporated into an assembled product, steel plates 34
inches or more in thickness shall be blast cleaned when required to remove rolled-in mill scale,
impurities and non-metallic foreign materials. After assembly, all weld flux shall be
mechanically removed. The iron or steel product shall be degreased by immersion in an
agitated 4.5% - 6.0% concentrated caustic solution elevated to a temperature ranging from 150
degrees Fahrenheit to 190 degrees Fahrenheit. It shall next be rinsed clean from any residual
effects of the caustic or acid solutions by immersion in a circulating fresh water bath. Final
preparation shall be accomplished by immersion in concentrated zinc ammonium chloride flux
solution heated to 130 degrees Fahrenheit. The solution's acidity content shall be maintained
between 4.5 - 5.0pH. The assembly shall be air-dried to remove any moisture remaining in the
flux coat and/or trapped within the product.
Zinc coating - the product shall be hot-dip galvanized to the requirements of either ASTM A123
(fabricated products) or ASTM Al53 (hardware items) by immersion in a molten bath of prime
western grade zinc maintained between 810 degrees Fahrenheit and 850 degrees Fahrenheit.
The entire product shall be totally immersed with no part of it protruding out of the zinc (no
double dipping). This is to limit a risk of trapped contaminates containing chlorides and reduce
the risk of bare spots (bare spots can occur when flux on the steel surface is burned away by
heat of the first dip). Maximum aluminum content of the bath shall be 0.01%. Flux ash shall be
skimmed from the bath surface prior to immersion and extraction of the product to assure a
debris free zinc coating.
Exterior coating - all galvanized exterior surfaces shall be coated with a urethane or triglycidyl
isocyanurate (TGIC) polyester powder to a minimum film thickness of 2.0 mils {0.002"). Prior to
application, the surfaces to be powder coated shall be mechanically etched by brush blasting
(ref. SSPC-SP7) and the zinc coated substrate preheated to 450 degrees Fahrenheit for a
minimum of one hour in a gas fired convection oven. The coating shall be electrostatically
applied and cured in a gas fire convection oven by heating the zinc coated substrate to a
minimum of 350 degrees Fahrenheit and a maximum of 400 degrees Fahrenheit. The
thermosetting powder resin shall provide both intercoat as well as substrate fusion adhesion
that meets SA or SB classification of ASTM D3559.
