The invention relates to a tank truck end plate having a wave-shaped brink reinforced ring. An arced convex portion and an arced concave portion are continuously formed on the periphery of the end plate of the tank of the tank truck, and the region of the frame periphery of the arced concave portion is formed with an arced convex surface, which has the curvature greater than the curvature of the arced convex surface of the end plate of the tank of the conventional tank truck. According to this design, the end plate has the enhanced strength, surface smoothness, smoothness and straightness of the distal end of the periphery and the overall smoothness.
