Why stainless steel?
There are no special measures to be taken during the
winter. In case the filled pool has a frozen surface, the
ice does not attach to the stainless surfaces; there is no
damage through ice-pressure. No technical appliances are
needed to keep the walls of the pool ice-free because of
the heat-conducting characteristics of stainless steel. At
temperatures around 4°C and below, which is the temperature
at which water reacts abnormally and expands, the metal
conducts the heat of the water to the bottom side of the
ice-layer so that the ice melts on the edges, and therefore
cannot create pressure on the pool walls.
