Sternberg Lighting Inc. warrants that for a period of five (5) years* (the "Limited Warranty Period") from the date of shipment, that Sternberg's Paint Finish:

  • Will not fade in color more than five units as measured by Hunter L*a*b* Color Difference as set forth in ASTM D2244 Section 6.3 as of the date of this letter and in such a way as to significantly adversely affect the appearance of the surface to which the product has been applied and result in damage to the surface;
  • Will exhibit gloss retention of a minimum of 30% of the original as measured in accordance with ASTM D523 using 60 degree readings;
  • Will not chalk in excess of standard number 8 rating for colors, No. 6 for whites as illustrated in the ASTM D4214 Test Method A.
  • Will not corrode or exhibit a lack of adhesion.

* Sternberg Steel Poles are limited to a one (1) year warranty. Longer warranty periods are available based on selection of various optional surface preparation requirements for a particular geographic location. Consult factory for details.

Terms and Conditions

MEASUREMENTS: Color measurements (delta E) are measured at 10 degrees and on exposed coated surfaces that have been cleaned of all external deposits including chalk and compared to the original unexposed coated surface. For comparison purposes, Sternberg will maintain a standard paint panel and/or documentation indicating color, gloss and other properties. It is understood that fading may not be uniform if the coated surfaces are not equally exposed to the sun and weathering elements. Prior to the determination of a gloss value using an angle of incidence of 60 degrees following ASTM D523, the surface must be cleaned using a 1% aqueous solution of a wetting agent with a soft sponge under light pressure. This warranty extends only to parts exposed to normal atmospheric conditions in the United States. In addition, a systematic maintenance program must be instituted to clean the surface periodically so as to prevent accumulations of salt deposits and harmful pollutants.

MAINTENANCE: The cleaning recommendations for Sternberg Paint Finish is an integral part of the warranty given for gloss, color retention, and chalking. The warranty requires that regular cleaning has to be performed periodically, at least once a year and twice a year for structures directly exposed to areas of high salt concentration, such as near a seashore.

Suggested maintenance program

  • Clean water with slight amounts of mild alkaline detergents must be used.
  • The cleaning effect maybe increased by rubbing with a soft, non-scratching cloth or cotton with modest pressure.
  • The temperature of the parts to be cleaned must not exceed 80 F.
  • For removal of grease and oily substances isopropyl alcohol may be used.
  • The cleaning solution must not be allowed to react for more than one (1) hour.
  • After cleaning, the surfaces must be rinsed with clean cold water.
  • A proper maintenance record has to be kept and documented. This documentation must contain the following information:
    • Date
    • Name and Address of performing party
    • Description of cleaning procedure and detergents used
    • Signature of person performing the cleaning procedure
