DURAGALV® Is Enhanced Hot Dip Galvanizing For Today's Steel.

Corrosion Protection And Long-Lasting Good Looks
A unique blend of special high grade zinc, nickel, and other earthly metals combined with processing systems dedicated to maximizing the aesthetic of the steel product makes Duragalv an ideal choice for decades of steel corrosion protection and long-lasting good looks.

Galvanized Steel With Aesthetic Appeal
We realize that the professional community demands more than just steel corrosion protection. The galvanized steel must have an aesthetic appeal as well, whether it will be left in its galvanized finish or primed and painted. Duragalv combines the best of both worlds.

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

What Makes Duragalv Special?
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.

Environmentally Friendly And Green Too
Best of all, Duragalv is environmentally friendly and is a “partner” in the “Green Building” community.

Duragalv Short Form Specification

 2.XX        HOT-DIP GALVANIZING - DURAGALV

A.       Hot-Dip Galvanizing:  Provide coating for iron and steel fabrications applied by the hot-dip process, Duragalv® by Duncan Galvanizing.  Comply with ASTM A 123 for fabricated products and ASTM A 153 for hardware.  Provide thickness of galvanizing specified in referenced standards. The galvanizing bath shall contain special high grade zinc, nickel, and other earthly materials.

B.       Galvanizing shall exhibit a rugosity (smoothness) not greater than 4 rug (16-20 microns of variation) when measured by a profilometer over a 1 inch straight line on the surface of architectural and structural elements that are less than 24 pounds per running foot.  Profilometer shall be capable of operating in 1 micron increments.

1.     Surface blasting prior to application of factory-applied post-galvanizing wet coatings will produce a high rugosity and not be acceptable.

C.       Quality Assurance for Hot-Dip Galvanizing:

1. Galvanizing shall be performed by a company with a minimum of ten years experience in the successful application of hot-dip galvanizing utilizing the dry kettle process.
2. Engage the services of a galvanizer who has demonstrated a minimum of ten years experience in the successful performance of the processes outlined in this specification in the facility where the work is to be doneand who will apply the galvanizing and coatings within the same facility as outlined herein. The Architect has the right to inspect and approve or reject the galvanizer/galvanizing facility.
3. The galvanizer/galvanizing facility must have an ongoing Quality Control/Quality Assurance program acceptable to the Architect which has been in effect for a minimum of ten years and shall provide the Architect with process and final inspection documentation.

4       Touch-up damaged galvanizing after installation using organic zinc coating complying with ASTM A780 and as recommended by galvanizer.
5.      Certificate of compliance that the galvanizer has certified weighers on premises with a certification from the local municipality, and a certified scale or municipal scale has been utilized by the galvanizer.
6.      Fabricator shall provide a notarized statement from the galvanizer, along with a description of the material processed, indicating that all work has been done in conformance with this specification prior to receiving payment.
7.      Certificate of Compliance for Shop Drawing Review by Galvanizer:  Submit galvanizer's certification that shop drawings for metal fabrications to receive metal coatings have been reviewed and that fabrications are acceptable to galvanizer for proper application of galvanizing and metal coatings. All drawings should be stamped by the galvanizer to indicate approval of design for galvanizing.
8.      Substitutions shall not be considered unless approved by Architect, Owner/Owner's Representative, and Contractor. Substitution requests shall be accompanied by proof that the substitution meets or exceeds the performance, aesthetic and durability requirements of the specified Duncan process. Coatings not matching approved submittals shall be removed and replaced at no additional expense to the Owner
9.      Galvanizer/coater shall supply a certificate of compliance that all coatings have been performed in accordance with QP-3 standards and procedures.
