Product Description
Our company specializes in producing ordinary, galvanized and stainless steel sheet metal water stops with the following specifications: 200*2, 200*3, 300*2, 300*3, 350*2, 350*3, 400*4, 330*5, etc. Metal plate waterstop is a common material in engineering, including steel plate, copper plate, alloy steel plate, etc. It is mainly used in reinforced concrete structures, dams and other large projects. The use of metal plate waterstop can change the path of water penetration and extend the route of water penetration. In the construction environment where the seepage water may contain corrosive components, the metal plate waterstop can play a certain role in anti-corrosion. In protection projects, the use of sheet metal water stops can ensure the protective effect of the project. Metal plate waterstop is also commonly used in projects with high seepage resistance requirements and small areas, such as casting pits in smelters, electric furnace pits, etc.
Precautions:
Construction should pay attention to the specification, size and shape of the waterstop in line with the design requirements. Generally for the convenience of operation processing into ≤ 2m per section, construction should pay attention to the lap, weld surface should pay attention to welding, the corner should be handled reasonably, a good water stop steel plate should be fixed firmly with the wall (or plate) reinforcement. Steel plate should be straight and not twisted. Horizontal seam using steel plate waterstop should be careful.
