FRP lock gates and stoplogs

The common weakness in conventional lock gates is that they can rust or rot. So that requires good maintenance, with the result: obstructions. FiberCore Europe is the inventor of FRP lock gates and stoplogs. Extremely strong, practically maintenance-free and very sustainable. They last longer than 100 years. More and more governments and construction companies are therefore opting for FRP lock gates and stoplogs.

Very strong

FiberCore lock gates and stoplogs have InfraCore® Inside. We developed this patented technology especially for extremely strong and yet lightweight constructions. The material comprises a mix of glass fibers and thermosetting resin. Result: lightweight lock doors that are extremely strong. We supplied, among other things, the largest lock gates ever made in FRP: more than 13 x 6.2 meters. This for a locks complex of Rijkswaterstaat in the Wilhelminakanaal in Tilburg (The Netherlands).

Low maintenance and safe

Our FiberCore lock gates and stoplogs cannot rust or rot. This makes them much stronger than wood or steel. And therefore safer.

Sustainable solution

Composite is the material for the future. Our lock gates have InfraCore® Inside. This ensures an extremely long lifespan of more than 100 years. Thanks to the smart prefab construction and the light weight, the lock door is easy to replace. More about sustainability

Competitive with traditional materials

FiberCore Lock gates and stoplogs are calculated based on strength instead of stiffness. That saves a lot of money. Our lock gates are therefore competitive with doors made of wood and steel. Our lock gates have been moving as successful construction material. Our constructions naturally comply with the Eurocodes.

Prefab production, easy assembly

We make your FiberCore lock gates in our own factory in Rotterdam (The Netherlands). The production time only takes a few weeks. We transport the prefab doors directly to the location where we assemble them. Thanks to the low net weight, this is quick and easy, with the least possible inconvenience to water traffic. Thanks to the low net weight, light pivots are sufficient.

Results of the Rijkswaterstaat investigation ‘MultiWaterWerk: Standardization of lock gates’

Composite lock gates: the material of the future

In the report ‘MultiWaterWerk; Standardization of Lock Gates’ composite lock gates from FiberCore Europe are the best on both MKI value and LCC score. Rijkswaterstaat (Dutch Ministry of Infrastructure and Water Management) investigated with the market how the VNR task for its 52 locks can be carried out efficiently. Rijkswaterstaat has commissioned the civil engineering market to conduct a comparison study into the materialization of lock gates. The aim of this study was to find out which material (timber, steel, composite or hybrid) scores best with certain dimensions of the doors in terms of environmental impact and lifetime costs.

Royal HaskoningDHV and FiberCore Europe have focused on the material composite as the market leader.

Our projects

In The Netherlands, Europe and far beyond you will now find more than 1400 bridges and numerous lock gates and stoplogs produced by FiberCore Europe. From bicycle bridge in the residential area to the world’s longest bridge span. And from a harbor bridge in the Port of Rotterdam to the world’s largest FRP lock gates. And we are proud of that!

Our secret? InfraCore® Inside

You can fully rely on our lock gates and stoplogs. They are extremely strong. This thanks to our unique InfraCore® technology. We developed this technology specifically for building extremely robust panels, without internal gluing or bolted connections. The InfraCore® technology is based on the principle that there is a continuous structural connection of glass fibers between the top and bottom of the construction. This prevents delamination and ensures that our bridges retain their strength and solidity. Even after many decades. Even after 100 years.
