The invention discloses a high strength and energy saving flexible bridge frame, which includes a bridge frame shell. The bridge frame shell is externally provided with a protective coating formed by paint, and the paint is composed of polyurethane, epoxy resin, acrylic resin, polytetrafluoroethylene, polyethylene glycol, butanediol, linseed oil, alumina, ceramic powder, silicon powder, cerium oxide, a solvent, a curing agent, aluminum potassium sulfate and sodium fluosilicate. Due to adoption of polyurethane, epoxy resin, acrylic resin and polytetrafluoroethylene by the invention, the high crosslinking density paint can be formed through mutual synergistic effects of the resins. The paint has extremely high surface hardness, excellent flexibility, bending resistance and flexibility, and excellent physical and mechanical properties, thus being able to avoid stress concentration. Therefore, the film formed by the paint has very good tensile strength, tear strength and stone impact resistance, thereby ensuring the service life of the bridge frame.
