PRIMERGALV®

SPECIFICATION

Galvanized Steel Building Galvanized T Sign Galvanized Quonset

PRIMERGALV® is a factory applied universal primer for freshly galvanized steel which is to receive a field applied topcoat.

Ideal For Fast Tracking Projects
This process guarantees a tenacious bond between the galvanized steel and the prime coat and eliminates virtually all the problems associated with painting hot dip galvanized steel. It is the ideal process for those projects that are "fast-tracking" yet have not made a color selection or those projects where there is an inordinate amount of field welding.

Are You Painting Galvanized Steel?
With Primergalv, poor field touch-up is a thing of the past!

Primergalv Short Form Specification

2.XX        HOT-DIP GALVANIZING AND FACTORY-APPLIED PRIMER - PRIMERGALV®

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.

NTS: Delete paragraph B if priming is over "black steel"

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.       Factory-Applied Primer:  Provide factory-applied prime coat, Primergalv® by Duncan Galvanizing, certified VOC compliant, conforming to applicable regulations and EPA standards.  Apply primer within 12 hours after galvanizing and within 3 hours of surface preparation at the same facility where the galvanizing is done in a controlled environment meeting applicable environmental regulations and as recommended by the primer coating manufacturer.  Blast cleaning of the surface is insufficient for surface preparation.

D.       Performance Criteria: Coatings must meet or exceed the criteria for the following categories as stipulated by the coatings manufacturer:

E.       Quality Assurance for Hot-Dip Galvanizing and Factory-Applied Metal Coatings:

  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. Factory-applied metal coatings shall be performed in a facility acceptable to the coating manufacturer.
  3. Submit two 3 inch by 6 inch samples of factory-applied coatings and colors proposed for use for approval prior to coating application.
  4. 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  within the same facility as outlined herein. The Architect has the right to inspect and the facility where the work is to be doneand who will apply the galvanizing and coatings approve or reject the galvanizer/galvanizing facility.
  5. Handle and install materials with factory-applied coatings as recommended by galvanizer and coating manufacturer to prevent damage to coatings prior to and after installation.
  6. Touch-up factory-applied metal coatings as recommended by galvanizer and coating manufacturer.
  7. 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.
  8. 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.
  9. 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.
  10. Substitutions or APPROVED EQUALS are defined as meeting the, aesthetic, durability and all other performance criteria as detailed in this specification. Substitution and/or APPROVED EQUALS requests shall be accompanied by proof that the substitution or APPROVED EQUAL meets or exceeds the aesthetic, durability and all other performance requirements of the specified Duncan Processes. Approvals of the substitution and/or APPROVED EQUALS shall be the right of the Owner, Owner’s Representative, the Architect or the Engineer. Coatings or processes not matching or exceeding the approved specified process including aesthetic, durability and all other performance criteria shall be removed and replaced at the expense of the contractor and all subcontractors that were involved with the supply of, and the application of the non conforming product. Intentional misrepresentation of processes is fraud.
  11. Galvanizer/coater shall supply a certificate of compliance that all coatings have been       performed in accordance with QP-3 standards and procedures.
