Lock Gates / Flood Gates / Sluice Gates

Hupkes Wijma has long standing experience in the construction of lock gates, flood gates, mitre gates and sluice gates.  All Hupkes Wijma lock gates are precisely designed to meet the specific requirements of the canal or waterway for which it is needed.  With particular emphasis on structural hardwoods like Ekki, Greenheart and Oak we can provide a complete design and manufacture service, or supply to detailed customer specifications.

Our gates are manufactured to an exceptional degree of tolerance, at our purpose built mill and workshops in the Netherlands, utilising specialist CNC capabilities in combination with our highly skilled craftsmen, where we combine tried and tested methods, and design in accordance with Eurocode 5 to produce a high quality lock gate that will provide a low to no maintenance, extremely durable and effective water management system.

FSC® certified Ekki Lock gates

Traditionally, lock gates have always been made from timber.  Originally they would have been manufactured in Oak, however Ekki or Greenheart is often used as an alternative due to the increased lifespan and superior mechanical properties these timbers offer, in some cases resulting in less Ekki or Greenheart being necessary than an alternative timber species.

Hupkes Wijma hold extensive stocks throughout Europe, in constructional hardwoods like Ekki and Greenheart which are used in the manufacture of our structures, combined with the facility to produce sawn and machined sections of Ekki at our mill in the Netherlands enable us to meet even the most challenging demands promptly.

As well as manufacturing lock gates and supplying machined sections, our workshops offer a refurbishment service for heritage projects.  Many of the cast fittings are recycled and then reused on the new lock gates, new steel brackets are fitted to strengthen the joints to maximise durability while preserving the heritage characteristics, with hoops, and other bespoke steel fittings designed and manufactured to suit each lock gate produced.

Ekki mitre gates offer a minimal maintenance product that has proven it will function for many decades, outperforming many of the steel or composite designs that have tried to replace it.
