Effective Corrosion Protection For Galvanized Steel, Black Steel And Metal Substrates

Protecting Steel Since 1890
Duncan Galvanizing has always been on the cutting edge of metal corrosion protection. From hot dip galvanizing milk containers in the late 1890's to creating a patented process in the 1960's for painting galvanized metal (Colorgalv®), we provide state-of-the-art hot dip galvanizing and high-tech architectural finishes for ANY metal substrate, including galvanized steel and "black steel" (uncoated steel).

Galvanizing And High-Tech Architectural Finishes

What is DURAGALV®?
Duragalv® is enhanced hot dip galvanizing for today's steel. Similar to the successful formula of our Nigalv® galvanizing system, Duragalv addresses the requirement for "Green" building and is recommended for those projects where the LEED standards are required. A unique blend of special high grade zinc and other earthly metals combined with processing systems dedicated to maximizing the aesthetic of the steel product, makes this an ideal choice for decades of corrosion protection AND long-lasting good looks.

Duragalv® uses a series of alloying elements designed to increase the toughness of the coating. It is harder than typical galvanizing. The alloys on the surface include more iron which makes the coating harder than the base steel. In some cases it is 200% harder than the steel being coated. This hardness provides greater durability.

What is PRIMERGALV®?
Primergalv® is a factory applied universal primer for freshly galvanized steel, "black steel" or aluminum which is to receive a field applied topcoat. This process guarantees a tenacious bond between the metal substrate and the prime coat and eliminates virtually all the problems associated with field-painting. It is the ideal process for those projects that are “fast-tracking” yet have not made a color selection or where field welding is anticipated and the client does not want to touch-up a factory finished product.

What is COLORGALV®?
Colorgalv® is a factory-applied high performance architectural color finish for hot dip galvanized steel and has been issued U.S. Patent #5641543. It is a process that is available in any color and warranted for twenty years against rust. Since the mid 1960's, Colorgalv® has been providing the architectural and engineering community with a long lasting system that combines corrosion protection with the aesthetics of color.

What is COLORGALV®10?
Colorgalv10® takes the Colorgalv® process referenced above one step further. It is not only warranted for twenty years against rust, but also utilizes unique architectural color finishes for even longer lasting beauty.

What is the DUNCAN FAMILY OF THERMOSET COATINGS?
Duncan Galvanizing's family of Thermoset coatings are produced from dry powders for a variety of applications. Thermoset coatings are environmentally friendly, producing virtually no Volatile Organic Compounds (VOC's). They are the ideal choice when designing for LEED (Leadership in Energy and Environmental Design) certification. The following chart illustrates the recommended applications for the various coatings.

Duncan Thermoset^SM can be applied over aluminum or black (uncoated) steel. After the Duncan Thermoset material is applied, the coated parts are “high heat cured” to provide an extremely durable finish. The color range available with Duncan Thermoset is virtually unlimited and even small jobs can be given special colors.

Duncan Primer Thermoset^SM can be applied over “black steel” or aluminum which is to receive a field applied topcoat. This process guarantees a tenacious bond between the metal substrate and the prime coat and eliminates virtually all the problems associated with field-painting. It is the ideal process for those projects that are “fast-tracking” yet have not made a color selection or where field welding is anticipated and the client does not want to touch-up a factory finished product.

Duncan Primergalv Thermoset^SM can be applied over freshly galvanized steel which is to receive a field applied topcoat. Similar to other Duncan Primer processes. The process guarantees a tenacious bond between the metal substrate and the prime coat and eliminates virtually all the problems associated with field-painting. It is the ideal process for those projects that are “fast-tracking” yet have not made a color selection or where field welding is anticipated and the client does not want to touch-up a factory finished product.

Where corrosion of steel is a concern, Duncan Colorgalv Thermoset^SM, utilizing the Duragalv system as a base is the ideal choice. Duncan Colorgalv ThermosetSM is designed to be applied over a freshly galvanized surface. It is also available in a virtually unlimited color range.

Both Duncan Thermoset and Duncan Colorgalv Thermoset are available in a variety of formulations and textures.
