The difference between the manufacturing process: galvanized steel and seamless steel pipe two kinds of areas, galvanized steel surfaces were refers Huanggang galvanized steel pipe plant, there may be welded pipe, it could be seamless, seamless is refers to the steel manufacturing process, and seamless welding points. These corrosion resistant galvanized pipe, seamless steel pipe can withstand higher pressures. Because zinc galvanized steel protection, not easy to rust, galvanized steel seamless pipe lighter than if it is used in the balcony, it is best to use light galvanized pipe, seamless steel too with less suitable for balcony Because seamless steel pipe wall thickness, the natural weight is heavy, and expensive than galvanized steel seamless steel costs to be high, there is a very durable galvanized steel, far more than the useful life of seamless steel tubes. If the quality, the use of twenty years should not be a problem, of course, have to do the welding and paint steel pipe plant, not to affect the life of galvanized steel. Uses difference: galvanized steel in general is used to make fences, fence, fence, balcony fence. Widely used in municipal engineering, roads, factories, schools, development zones, gardens, squares, residential and other places.
