Real Customer Feedback
We installed these 630mm SMC covers at a municipal infrastructure project. The range of load classes allowed us to use the same product family across different traffic zones. The D400 units handle heavy truck traffic without any deformation. The sealing performance has been excellent through two rainy seasons. Much better than our previous concrete and cast iron solutions. – Tom W., Infrastructure Procurement Manager
