1. Differences in manufacturing process: Galvanized steel pipes and non-galvanized steel pipes are two categories of steel pipes. Zinc plating means that the surface of steel pipes is galvanized, and non-galvanized steel pipes are not.
2. the difference in durability: galvanized pipe is more resistant to corrosion, non-galvanized steel pipe can withstand higher pressure. Galvanized steel pipes are not easy to rust due to the protection of zinc, and galvanized steel pipes are lighter than ordinary steel pipes.
3. Differences in use: Galvanized steel pipes are generally used for fences, fences, guardrails, and balcony guardrails. Widely used in municipal engineering, roads, factories, schools, development zones, gardens, plazas, residential areas and other places. Non-galvanized steel pipes are now largely replaced by galvanized steel pipes.
