Yes it can, just use a premium paint.
Wood doors use stile and rail construction by joining multiple components to create an overall design that is architecturally correct and features defined details in and around the panels. Wood doors are quite durable, they are not the most energy efficient. As with all exterior products, they require maintenance and should be refinished annually to retain their beauty and avoid issues caused by moisture. However, when properly cared for, a wood door can last for many years. Fiberglass doors are two large molded skins with a polyurethane foam core between the skins which is a great insulator against heat and cold. The fiberglass sheets, along with the foam core, do not absorb moisture and therefore eliminate the rotting, warping, peeling, and bubbling that can affect other exterior doors. Fiberglass doors mimic the grain of real wood doors and can be painted or stained. They are popular for their high insulation values, low maintenance, and resistance to dents and scratches. Steel doors can be painted and feature the same polyurethane foam core found in fiberglass doors, therefore offering the same insulating protection against cold and heat. Steel doors will either be hot or cold to the touch depending on exterior weather conditions. Steel doors are economical and offer good insulation, require low maintenance if placed in a fully protected exposure, and won't rot. However, steel doors are highly susceptible to rust and can easily dent.
Yes the door can be painted, but we do not have option to do it from the plant.
