The world’s largest FRP lock gates
In 2016, the largest composite lock gates in the world were installed in the Nieuwe Sluis III of the Wilhelmina Canal in Tilburg. Lock gates of these dimensions (6.2 by 12.9 meters) have never been installed before. The pointed doors can reverse a difference in water level of no less than 7.90 meters.
The exterior of each composite lock gate consists of 35 mm thick glass fiber reinforced polyester; the inside is made of foam. This makes the door light and can be opened and closed with less force. The lock gates have almost the same weight as water. This results in minimal friction for the hinges and ensures less wear. Partly because of this, they last three times longer than conventional lock gates. The doors have a beige / yellow coat layer and are low maintenance.
The project widening the Wilhelmina Canal of Rijkswaterstaat is thus a sustainable world first.
