The difference in manufacturing process: galvanized steel pipe and seamless steel pipe are two categories of steel pipe, galvanized steel pipe surface is galvanized, can be welded pipe, can also be seamless pipe, seamless steel pipe manufacturing process is welded, and is seamless. Galvanized pipe corrosion resistant, seamless steel pipe can withstand higher pressure.

Galvanized steel pipe due to the protection of zinc, not easy to rust, galvanized steel pipe is lighter than seamless steel pipe, if used for balcony, it is best to use galvanized bright pipe, seamless steel pipe is not suitable for balcony, due to the thick wall of seamless steel pipe, the natural weight is heavier, and the cost of seamless steel pipe is higher than the cost of galvanized steel pipe, and galvanized steel pipe is very durable, the service life is much longer than seamless steel pipe. If the quality is good, the use of more than 20 years is not a problem, of course, to do a good job of welding and painting, will not affect the service life of galvanized steel pipe. Difference in use: Galvanized steel pipe is generally used to make fences, fences, fences, balcony fences. Widely used in municipal engineering, roads, factories, schools, development zones, gardens, squares, residential areas and other places.
