Below are frequently asked questions about Duncan Galvanizing, our processes, and our plant. For general questions about hot-dip galvanizing, visit the American Galvanizers Association's informational resources here. For additional questions or information, give us a call at 617-389-8440.
Duncan does not maintain daily pricing and does not provide verbal quotes by phone. Reach out to our team with project details and we will provide you with a written quote as soon as possible.
You can fill out a credit application on our website. We will process the application and review your credit status with you upon completion.
Since hot dip galvanizing is a full immersion process, the cleaning materials and zinc must go “in, around, over, under, and through” the complete fabrication. Without the vent holes, the material will become trapped in the fabrication and could leave bare spots and, with the entrapment of steam, could possibly burst the fabrication and injure nearby employees, and will damage your material. If desired, for aesthetic reasons, Duncan can plug the holes after galvanizing
Duncan can provide all documentation relative to sustainability including Hazardous Product Declarations and Safety Data Sheets. We can also provide LEED certification for credit on your project.
Our production schedule and backlog changes daily. Work is usually processed in the order it is received, and we can only estimate our turnaround time based on if we know a date certain that material will be delivered to Duncan.
Our goal is to turn all galvanizing jobs within 2-3 days and all Colorgalv jobs in 5-7 days. Our backlog can be longer at times but we will do our best to accommodate your turnaround schedule.
Duncan does not provide transportation services but can recommend outside trucking firms if requested.
Yes, Duncan has a fleet of forklifts and handling equipment to ensure safe unloading of customer products.
Upon arrival, a driver should be directed to our scale in the center of the yard when clear, and proceed to wait for a mechanically audible indication that the weight has been taken.
Next, he or she should find a safe place to park, unstrap and wait for a lift operator to unload.
During this time, it is advisable to proceed to the customer service window under the awning on the left side of the yellow “house” and exchange paperwork for the order being delivered.
The Driver will be provided a tag to tie to the material and after unloading should visit the scale again to be weighed outbound.
Appointments are not necessary. However, if you would like a “driver will wait” delivery, we advise that you call our shipping department to see if there are available slots.
Duncan’s lunch and learn presentations provide 1 AIA CEU. For non-AIA members, we can provide a Certificate of Attendance for submittal.
The molten zinc in the galvanizing kettle is of uniform color. The Colorgalv process involves properly preparing the galvanized steel to receive our Duplex coatings. Virtually any color can be applied to our properly prepared in a variety of coatings to handle the harshest environments.
The touch up specification for hot-dip galvanizing is ASTM A780. Zinc rich coatings can be applied to the affected areas per this specification. For our Duplex Coating Systems, repair procedures can be provided to address touch up needed depending on the damage that has occurred.
Duncan uses only those coatings that are designed for a factory application and compatible with hot dip galvanizing but we can match any manufacturer’s color and will provide a sample for approval.
Duncan can provide touch-up material for damaged Colorgalv and repair procedures for the proper preparation and application.
