Plastic-steel stay

The utility model discloses a novel foot step for climbing when the wells and the structures of various urban underground pipelines are checked, solving the problems of the corrosion and the impacting brittle failure of the present steel or cast-iron foot step and personal and production safety. Corrosion resistant plastic material is wrapped at the circumference of a steel core, obtaining the goal of corrosion prevention, and the steel core has favorable impact toughness; the corrugated inner side and the pattern and the reflecting point of the convex-concave surface of the foot step can ensure the personal and production safety up to the hilt. In the attached figure, plastic material (2) is wrapped at the circumference of the steel core (1); the reflecting point (3) is positioned at the surface of the foot step.
