Project Details
Like many existing timber structures in New York and New Jersey, a deteriorating timber pile bulkhead (located in New York City’s Upper East Side) needed to be replaced. The New York City Department of Transportation selected the largest and most expensive steel sheet piles as the replacement. In addition, SeaShield Rigspray™ was specified as the coating of choice to protect these new sheet piles.
A total of 212 sheet piles, that measured 6 ft. x 75 ft. (1.83 m x 23 m) were coated with SeaShield Rigspray in a steel plant in Pennsylvania. Over 8,000 gallons (30,280 litres) was used to coat the 300,000sq.ft. (27,870 sq. meters). Once completed, the coated steel sheets were transported to the Manhattan jobsite where they were prepped for installation.
Due to the sheer size and weight, 15,000lbs (6,804 kgs) per sheet pile, a crane was first used to position the sheet piles in place before they were driven into the mud line.
In recent years, more engineering companies have been specifying SeaShield Rigspray as the coating of choice, to protect steel structures in corrosive marine environments.
