When Danvers High School in Massachusetts embarked on a $70.9-million renovation and expansion project, staying within the budget and on schedule were at the top of its priority list. The first floor of the three-story academic building was clad with insulated precast concrete panels to provide a new ‘skin’ for the structure. Expanding the precast to the upper two stories was too expensive, so the architects looked to metal paneling to provide the look and feel they desired.
Structural steel has been the material of choice in the building market for decades because of the numerous benefits it provides. While steel offers an effective and efficient framing system for the building envelope, the hot-dip galvanizing of both interior and exterior elements is one method to provide a durable and maintenance-free corrosion protection system for generations.
Galvanized sheet is used in many industries, including construction, automotive, appliance, electrical hardware, drainage, and HVAC. While there is much information about the corrosion rate of zinc in the myriad environments where this product is used, the specified zinc coating mass is sometimes not suited for the end use.
