Chilled concrete slab The surface ice is kept at the required temperature by using a refrigeration system pumped through pipes embedded in the concrete slab below the skating surface. The ideal temperature of the rink surface is around -4C for ice hockey.

The word "rink" is a word of Scottish origin meaning, "course" used to describe the ice surface used in the sport of curling, but was kept in use once the winter team sport of ice hockey became established.

The point is a term in ice hockey to indicate a position inside the opposition's blue line along the edges of the rink.

Rink “Zones” The ice surface is divided into three zones. The area where the goal net is located is the “defending zone” for the team defending that net. The middle of the rink, between two blue lines, is the “neutral zone.” The area where the opposing net is located is the “attacking zone” or “offensive zone.”
