PURPOSE: To provide a coated steel pipe for construction with excellent corrosion resistance and excellent warmth sensitivity when a person touches its surface with his hand especially in winter season. CONSTITUTION: A warmth-sensitive coated steel pipe wherein an epoxy- polyethylene coating 3 with a foaming ratio of 1.5-10 times is applied on a steel pipe 1 wherein the scale on the surface is removed by means of blast processing and being treated with an undercoating treatment, is provided. Therefore, it can be used as a material for construction with excellent corrosion resistance, without feeling coolness especially at cold period caused by warmth sensitivity. |
