Our toboggan will be built using several different materials, including alluminum, steel, carbon fibres, and of course, concrete. A selection of sites have been chosen to provide a background on the various materials which may be used in constructing "STONE COLD" or which you may see on construction sites near you.

Steel is used as a reinforcement in order to provide the necessary tensile resistance.
Alluminum is used in place of steel, whenever possible, to reduce the total weight.
