This rattan dining table set is craft using powder coated aluminum frame work which offers protection from rust and corrosion, even during damp conditions. The rattan weave is PE synthetic rattan, also famed for its weatherproof qualities and is protected from the sun's UV rays, meaning it will not fade, as well as frost and snow so it will not crack or go brittle.This allows you to leave your rattan outside all year round, even though the coldest and dampest months, without damage to your set.
