Metrolina Greenhouses and the VanWingerden family have been building greenhouses in Huntersville, North Carolina since 1972. For the last several years they have been working on a 40+ acre expansion to grow the current 162 acres of greenhouse to more than 200+ acres under roof – making it the largest single-story structure in the United States. Since their inception in 1972, Metrolina has chosen to hot-dip galvanize every single steel component of their greenhouse structures.

The decision to hot-dip galvanizing this large expansion was based on a number of reasons. First and foremost was their prior success with the galvanizing coating.In addition to prior success; initial cost, corrosion performance, coating durability and ease of specifying all played a part in the decision for this two-phase expansion. The VanWingerden family will continue to specify galvanizing as they continue to grow the property to supply flowers to all the large regional hardware and discount stores.

This expansion project began back in 2018, and has taken Metrolina nearly three years to complete. All the deliveries were staged at the galvanizing facility and taken to the project by the galvanizer when they were completed. This allowed for a very smooth project. Any items that may have had fabrication problems or delays were able to be quickly sent over to the galvanizer rushed through for a quick turnaround time.
