Table tennis table
The indoor table tennis table is made of compressed board. It is easy to blister on the surface when exposed to humidity and sunlight for a long period of time, which will affect the track of the table tennis. The traditional outdoor table tennis table is made of steel or marble which makes them waterproof, but also very low in elasticity and comes with uneven surface. Modern outdoor table tennis table is made of wood-based panel. Although the elasticity is not as good as the compression board, it is better than steel and marble.
