| Message: | Steel edge rubber waterstop is a kind of buried rubber waterstop. It is a modification of traditional rubber waterstop due to its steel edge of two sides. Steel plate is galvanized steel; rubber part is made from natural rubber or synthetic rubber, adding various additives and fillers, through the process of plasticizing, mixing, pressing, forming. Rubber part can have center bulb or not. The waterstop can be divided into high-strength area, water-proof area and the installation area, and installation area has punched holes to install easily. Its unequal thickness structure can ensure each part of the sections can get uniform and reasonable force. It has high tensile strength, good waterproof performance, good elasticity, can resistant to rust, wear, aging, tear, corrosion, can waterproof well. It is usually used in water conservancy projects, dams, tunnels, basements, slabs, wall junctions.
