Due to the revisions of the common parameters on the market, SERIUS has improved the surface boxes in many parts. In order to fulfill the high demands on quality on the part of the fabricators and users, we always set our focus on Made in Germany.
Important to SERIUS is above all the onsite controlling of all quality guidelines and regulations. So if necessary, we can immediately take influence on the production. And by now, SERIUS already created 15 new working places in Germany due to the decision to produce in Germany.
The currently valid regulations that are the basis for the applied surface boxes derive in some extent from the thirties of the last century. As surface boxes were a relatively simple component, years-long, they hardly were in the focus of the inventors. Consequently, the forms as well as the applied materials are on a level that doesn’t stay abreast in all areas with the technical progress. First improvements were the introduction of the height-adjustability and the plastic base body.
High costs that are produced due to deficient products or materials concern the companies that maintain roads and utility nets. Only the damages that are produced due to the increasingly growing heavy goods vehicle traffic and the hence ensuing lane grooves, where in most of the cases also surface boxes are situated, generate enormous costs even without laying a new road surface.
Frost heave or clacking noises are still a burden for the users of the roads, the companies that maintain the roads and the residents. All these problems are easily avoidable if the manufacturing and the right choice of the products meet the purpose.
And even if repairs are necessary, on the one hand, it should be at a low cost and on the other hand, presenting an even more important aspect, also sustainably successful. But one thing is certain that mistakes that are done during a road construction can only be cleared with a high financial effort.
Further problems result from mud and corrosion. Consequently the surface boxes are difficult to open and a water closure or water supply for the fire service is impossible. Thus the cover has to be opened forcefully and then replaced.
