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.

Concrete is an artificially engineered material made from a mixture of portland cement, aggregates (such 
as sand or gravel) and water. Concrete has great strength in compression, but little tensile strength. 

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.
