Raw Materials of roller coaster

Roller coasters are generally classified as either wooden coasters or steel coasters depending on the materials used for the support structure.

Wooden coasters use massive wooden trestle-style structures to support the track above the ground. The wood is generally a construction grade such as Douglas fir or southern yellow pine and is painted or otherwise treated to prevent deterioration. The wooden components are supported on concrete foundations and are joined with bolts and nails. Steel plates are used to reinforce critical joints. As an example of the immense number of parts required to build a wooden coaster, the American Eagle built for Six Flags Great America in Gumee, Illinois, used 2,000 concrete foundations; 1.6 million ft (487,680 m) of wood; 60,720 bolts; and 30,600 lb (13,910 kg) of nails. It was coated with 9,000 gal (34,065 L) of paint.

Steel coasters may use thin, trestle-style structures to support the track, or they may use thick tubular supports. The track is usually formed in sections from a pair of welded round steel tubes held in position by steel stanchions attached to rectangular box girder or thick round tubular track supports. All exposed steel surfaces are painted. Steel coasters can be just as complex as wooden ones. For example, the Pepsi Max Big One coaster at Blackpool Pleasure Beach in Blackpool, England, used 1,270 piles driven into the sandy soil for the foundation; 2,215 tons (2,010 metric tons) of steel, and 60,000 bolts. There were 42,000 sq. yd (35,087 sq. m) of painted surfaces.

The track and lift chain on both wooden and steel coasters are made of steel, and the cars usually have steel axles and substructures. The car bodies may be formed from aluminum or fiberglass, and the car wheels may be cast from urethane or some other long-wearing, quiet-running material.
