Galvan’s expertise and experience in progressive dipping was also important. Several column members and connecting support beams, along with most of the cellular beams were designed with lengths over 62 feet, requiring progressive dipping in the galvanizing kettle. This process requires the steel members to be dipped into the molten zinc once, and then removed for cooling. After the beams have cooled, Galvan team members grind the first dip line, and then place the steel beams back into the kettle for the second dip, getting the full zinc coverage required for specification from end to end.
Designing the steel members at greater lengths reduced the number of steel members required on the project, along with field splices that would have been required by designing smaller members. Due to increasing labor costs, field splicing has become very expensive, so reducing the number of them creates more project savings.
In addition to reducing overall material and installation costs, Galvan helped keep the project on schedule. All 81 loads were stored at Galvan’s galvanizing facility ungalvanized, scheduled for production, galvanized, stacked, and finally loaded for delivery to the jobsite as needed. Keeping all the loads stored and staged at one location facilitated scheduling and transportation – saving time and money.
There are many benefits to Atrium Health’s decision to use Galvan Industries for hot-dip galvanizing on this project. Knowing the coating will keep the parking structure maintenance free for decades in the future is always an added benefit for specifying HDG. The project team and owners of the hospital can rest easy knowing they chose the best coating system for a long, cost-efficient parking solution.
Specifying HDG helped the hospital save money during construction and will also save money in the future thanks to HDG’s maintenance free longevity. The savings over time will allow Atrium Health more opportunities for future expansions to benefit the community.
About the AGA
Founded in 1935, the American Galvanizers Association (AGA) is a non-profit trade association dedicated to serving the needs of fabricators, architects, specifiers, and engineers, providing technical support on today’s innovative applications and state-of-the-art technological developments in hot-dip galvanizing for corrosion control. The AGA maintains a large technical library, provides multimedia seminars, and offers a toll-free technical support hotline to assist specifiers in North America.
