The steel edged rubber composite sealing strip is a section of the use of non thick structure, a rubber sealing strip product strength and waterproof area, uniform stress, it is reasonable. Each part of the steel edged rubber water stop plate, additional mounting hole and the reinforced connection, fixation is not easy to make the displacement. The stress is uniform and reasonable. The telescopic hole Jiubi plane, in the construction of waterstop plate mold clamping large contact surface, easy mounting hole and dislocation; plate with reinforced connection, fixation is not easy displacement. Good adhesion of galvanized steel sheet and concrete, steel edged waterstop waterproof rubber composite with better performance. Steel edged waterstop (also known as: Rubber watertight strip) is the rubber sealing belt section with non thick structure, strong points and waterproof area area, each part of the stress is uniform and reasonable. The mounting hole and is connected with the sealing strip steel on steel plate fixation is not easy to make each part of the displacement, stress is uniform and reasonable.
