Our Premium Hot Dip Galvanizing finishing system for Iron and Steel with a 20 year warranty against rust.
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.
Duragalv is a unique blend of special High-Grade Zinc (the most environmentally sensitive zinc available) combined with processing systems dedicated to maximizing the aesthetic of the steel product. By combining nickel, utilizing the dry kettle process and creating extensive testing and monitoring procedures, Duncan has taken the art of hot dip galvanizing to the next level.
Since galvanizing is a metallurgical bond between the zinc and the steel, in some cases it is 200% harder than the steel being coated. This hardness provides greater durability allowing the Duragalv process to provide a twenty (20) year warranty against rust.With our in-house testing lab, we have the ability to test our zinc, acids, and other process components to make certain all appropriate standards are met.
Zinc-alloy coating (special high-grade zinc).
Any exposed steel not needing color.
