Testing and certification of our surface boxes according to DIN 3580
In the area of pipeline construction, the surface boxes are exposed to the highest loads due to the connection to the surface. Depending on the installation situation, heavy traffic, clearing vehicles, heat and cold, ice and snow affect the surface boxes. The fittings installed in them should be well protected, the surface boxes should be embedded at road level and the covers should function properly. They achieve this through professional installation, regular maintenance and the delivery of DIN-compliant surface boxes with DVGW certification.
