When buying solid wood composite doors, buy painted ones. Find a better brand that also meets your price requirements. Steel doors and steel-wood doors are at a lower level. They have a strong metallic feel and lack the warmth of wooden doors, but they are practical. There is also a distinction between adhesive tape and baking paint, so you should look carefully when buying.
