Colorgalv Thermoset Short Form Specification

2.XX        HOT DIP GALVANIZING AND HIGH PERFORMANCE THERMOSETTING BASED DURABLE COATING - DUNCAN COLORGALV THERMOSET^SM

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.
C.       Duncan Colorgalv Thermoset matching approved samples.

1. Factory-applied metal coatings shall be performed in a facility acceptable to the coating manufacturer.
2. Performance Criteria: Coating must meet or exceed the criteria for the following categories as stipulated by the coatings manufacturer:
   ADHESION – Method: ASTM D-3359 Result: 1050 psi
   FLEXIBILITY – Method: ASTM D-522 (Cylindrical Mandrel) Passes
   HARDNESS – Method: ASTM D-3363 (Pencil) 2H
   SALT SPRAY – Method: ASTM B-117 Result: Passes 400 hrs
   HUMIDITY – Method: ASTM D-4585 , 100° F,2000 hours
         Result: Passes, no cracking or delamination
   IMPACT RESISTANCE - Method: ASTM D-2794 Direct 160 in lbs
   COLOR RETENTION – ASTM D 2244 Result: 1∆E after 1 year
   CHALK RESISTANCE – ASTM D 4214 Result: None
   GLOSS RETENTION – ASTM D 523 Result: No decrease 1 year
   XENON ARC TEST: ASTM D 4798 Result: Pass 200 hours
   
3. Galvanizer shall create a profile on the surface to provide adhesion for the Duncan Thermoset.
4. All coating material shall be force cured in a calibrated oven capable of maintaining curing temperatures per the coating manufacturer’s specification.

D.       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. 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.
5. Touch-up factory-applied metal coatings as recommended by galvanizer and coating manufacturer.
6. Coatings not matching approved submittals shall be removed and replaced at no additional expense to the Owner.
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. Provide 20 year warranty against 10% or more visible rust. Warranties for fading or discoloration of the finish shall be that which is supplied by the coating manufacturer.
9. 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.
10. 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.
11. 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.
