ERW Pre-Galvanized Steel Round Pipe is a round pipe manufactured by high-frequency resistance welding (ERW) process. Its unique feature is that it uses pre-galvanized steel strip as raw material. This process of plating first and then welding ensures that both the inner and outer surfaces of the pipe are protected by a uniform zinc layer, which not only retains the efficient production characteristics of ERW steel pipes, but also provides excellent corrosion resistance. It is particularly suitable for application scenarios that require both cost-effectiveness and durability.
