Project Description

SPI earned the SSPC 2011 E. Crone Knoy Award in recognition for the performance of SUPER THERM, RUST GRIP, and ENAMO GRIP coatings at the Hoover Dam Bypass Bridge, also known as the Colorado River Bridge. The railings of the observation deck were treated with the 3 products. The observation deck expects 3-5 million visitors each year.

Coating Solution

After extensive testing, the SPI Coatings were selected for the railings surrounding the observation deck on the Bridge, which expects 3 to 5 million visitors each year. No other coatings could produce the level of corrosion protection, ease of application, and radiant heat reduction on the railings demonstrated by the SPI Coatings.

In submitting this project for recognition, Pacific United/Anco Services, a member of The Brock Group, said, “A very unique coating system was used on the project called SUPER THERM. This product reflects 95% of radiation from the sun. That is why the Federal Highway Department chose this product. The extreme temperatures of the Arizona/Nevada desert averages 95°F (35°C) o 110°F (43°C) on most days, with UV exposure from the sun.”


Superior Products International II, Inc. was recognized as the recipient of The Society for Protective Coatings (SSPC) 2011 E. Crone Knoy Award.

SSPC gives the E. Crone Knoy Award annually for outstanding achievement in commercial or industrial coatings work that demonstrates innovation, durability or utility. Qualities considered include use of state-of-the-art techniques or products to creatively solve problems. “We are thrilled to recognize this exceptional project” said JPCL editor-in-chief Karen Kapsanis, who presented the awards at SSPC’s first annual meeting and awards program at SSPC 2011 in Las Vegas. “The range of craftsmanship, commitment and ingenuity displayed in this project reflects the best of the best in our industry.”
