The present design relates to a railing pillar for the molding manufacturing process through the use of wood powder and plastic extrusion durable eco-friendly composite wood fence. In general, synthetic wood fence railing pillars of the present devise a bar combines the exterior made of synthetic wood on the base tube metal form a railing pillars, it initiated synthetic wood fence railing pillars, Mountain and lighting equipment for or the supply of electricity without any other reason, such as road conditions, terrain with limited lighting, sidewalks, walkways, decks, etc. loaded by maintaining a clear boundary fence and pedestrian circulation and to induce a safe passage. More detailed look at the maximum four sides from railings pillar material terrain and at least one according to the features surrounding conditions such as cotton which is made of a mixture of processing, including the wood powder and the resin constituting the exterior of the base extending in the vertical metal tube synthetic wood includes a plurality of guide seating portion groove and protruding aluminum support and the synthetic wood supporter plane that is inserted into the seating portion groove of the guide up to, and forming is coupled to the lower portion of the flat synthetic wood supporter and, as the coupling portion outer form a bond formed so that the combination is inserted into the seating portion fixing groove, and, to the outside of said coupling is via a fixing projection formed to be coupled are inserted into the fixing groove seating portion is a synthetic timber support fixed allow vertical line fluidity, luminous portion having the protruding aluminum carrier is lower in the luminous surface and the protruding aluminum support formed by forming a groove with a predetermined depth in the protruding sides of the triangle, and curing the phosphorescent pigment and the resin in the inner surface and form a bond and in the coupling section to the outside it is characterized in that the fixed position sikilsu requesting from the bottom to the top according to the vertically extending pillar material height through fixing projection formed to be coupled is inserted into the seating portion fixing groove.
