Doors are used to separate two sections. They are usually connected to the frames through hinges. Most doors are made out of wood and have metal hinges. Some doors have an inner metal core for higher durability, with wood panels on the outside, and others are just solid wood. You can also find doors that are made out of materials other than wood, for example, steel. However, steel doors are not very common. But if you are looking out for some, make sure to visit our website eWorldTrade.com to pick the door of your liking. Feel free to inquire about the same with any of our manufacturers and suppliers.
