Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a guardrail which makes stain hardly adhere to both a flat part 11 of a protrusion and a recess 13 of a beam 1 of the guardrail. SOLUTION: In this stainproof guardrail, the surface of the flat part 11 of the protrusion of the beam 1 of the guardrail exhibits hydrophilicity, and the surface of the recess 13 exhibits water repellency. Preferably, a water-repellent treatment agent is applied to the surface of the recess 13 of the beam 1 which is coated with a hydrophilic resin. COPYRIGHT: (C)2007,JPO&INPIT |
