HDI Railing Systems
Our Circum railing system is precise, customizable, and can be found inside of One World's Trade Center.
One World's architect was David Childs, whose firm Skidmore, Owings & Merrill (SOM) also designed the Burj Khalifa and the Willis Tower.
One World Trade Center became the tallest structure in New York City on April 30, 2012, reaching a total height of 1,776 feet (541 m). Its height in feet is a deliberate reference to the year when the United States Declaration of Independence was signed.
