TRENCH COVER
For all of the most popular supply channels
With our Trench Cover made from hanit recycled plastic, we have designed a product which provides a practical and reliable solution for covering cable trenches, shafts, or construction and workshop pits, because hanit is weatherproof and highly resistant to any environmental influences. There is no risk of rotting, which is a problem with wood covers. Compared to concrete covers, the light weight of our recycled plastic is an advantage because hanit Trench Covers are only one third of the weight of conventional covers. Not only does this save a considerable amount of money on shipping, but it also reduces installation costs, as by hand, without the need for large machinery. The robust recycled plastic also has several other advantages which are important for demanding industrial applications.
Even after years of outdoor use, hanit remains unbreakable, dimensionally stable, and withstands a high degree of mechanical and chemical stress from oils, acids, or alkalis without problems. A long period of reliable use without costly repairs and maintenance is guaranteed with Trench Covers. They are used in substations, industrial systems, and railway systems, where high requirements are placed on the materials used, and on occupational safety. Unlike concrete covers, there is no fear of corrosion, meaning that there is no risk of collapse, even after long periods of use, providing the lines and cables reliable protection. Our hanit Trench Covers have proven themselves many times over as partitions, whether for heavy-duty applications or storing valuable steel parts, because hanit provides permanent protection against expensive rust damage. Our Trench Covers are also an ideal solution for planking and as stair treads or for path construction – not least because of their ease of processing and assembly.

REFERENCE PROJECT TRENCH COVER
Power Station in Didcot, Oxfordshire, Great Britain
Didcot power station is a gas power station operated by RWE in the south of England, where Trench Covers have been in reliable use for many years. The project that we would like to present to you was implemented in 2014. New cabling was to be laid in the aforementioned power station. With this in mind, our customer, S C Civils and Maintenance Ltd, was looking for a reliable and durable trench cover solution. Previously, only concrete covers had been used in the Didcot power plant. However, these repeatedly resulted in high maintenance and repair costs, and could not satisfactorily fulfill the high safety requirements because cold cracks formed. S C Civils and Maintenance Ltd also saw room for improvement with regard to installation, since concrete covers are very difficult to adjust and install because of the heavy weight. More flexibility and easier handling were wanted here, since the cable trenches in the power plant are very complex, and cutting the panels to size on-site was unavoidable.
During the search for a suitable alternative, S C Civils and Maintenance Ltd found out about Trench Covers made from hanit recycled plastic, which promised to be the perfect solution for their problems thanks to its special material properties. It was particularly the durability and resistance to external influences, as well as the flexible and easy installation which motivated the customer to place the order with HAHN Plastics and rely on hanit Trench Covers. S C Civils and Maintenance Ltd is pleased with their decision, since the project was successfully completed within just four weeks, to their complete satisfaction. All the challenges during assembly, such as curved trenches, were dealt with without problems, and the financial advantages due to the reduced amount of maintenance are guaranteed to this day.
