New York City School Construction Authority Window Guards

For years, the New York City School Construction Authority (NYCSCA) had prohibited hot-dip galvanizing as the corrosion protection mechanism for window guards in Section 10720 of their Standard Specifications in favor of metallizing. Their rationale was that the quality of the galvanizing was unacceptable and the coating did not adhere to the zinc.

After four years of testing, submitting samples, and responding to a variety of technical issues, the galvanizer was able to prove to the Authority that it could receive a quality product that was long lasting and maintenance free if appropriate techniques and attention to detail were followed. Additionally, it was shown that the turnaround time for galvanizing was significantly shorter than metallizing. As a result, the NYCSCA approved a duplex system of hot dip galvanizing and powder coating for the window guards.

This approval will open up a sizable market and have a strong impact to the galvanizing industry.
