PVC door is made mainly of UPVC material. It is shaped and joined together firmly. Galvanized steel bars are added inside to make it stronger against wind.
It has many types: swing door, sliding door, film covered door, folding door and industrial fast rolling door.
This door keeps wind and water out well. It keeps room warm, resists rust and is easy to clean. But it is not strong enough against hard hits and not fit for long time outdoor use.
It is mostly used in wet indoor places like bathroom and balcony. It is also used in factories, warehouses and clean workshops. It is seldom used as main entrance door.
