A flexible fencing system capable of negotiating topographical variations of surfaces without any negative effect on the strength of the fencing system and comprised of an initial post, at least one intermediary post and an end post. Each of the initial and end posts includes a plate extending distally from the posts. The intermediary posts include two plates extending distally from the intermediary posts where the angle between the distally extending plates is 180°. Braces having plates at each end are located between and connect to the posts at connection points formed by the plates of the braces secured to the plates of the posts. The connection points form a hinge providing flexibility to either incline or decline the brace relative to the preceding post, the variation of the brace inclination or declination determined by the topographical variations of a surface.
