Factory Price BS 729 1.5 Inch 2.5 Inch Welded Gi Iron Tube Pre Galvanized Round Steel Pipe

The steel raw materials are first galvanized to produce galvanized strip steel, and then the steel pipes made by post-processing are called galvanized strip steel pipes, also called pre-galvanized steel pipes.

First, the steel raw materials are used to produce ordinary steel pipes of the required welded steel pipe specifications, and then galvanized. The galvanized steel pipes produced in this way are called hot-dip galvanized steel pipes, also called hot-dip galvanized steel pipes.

There is a big difference in price between these two types of galvanized steel pipes. Galvanized strip steel pipes are much cheaper than hot-dip galvanized steel pipes. This is because in terms of the thickness of the zinc layer, the steel pipes produced by the hot-dip galvanizing process will be thicker and have stronger anti-corrosion ability.

However, many customers still tend to buy pre-galvanized steel pipes when inquiring about the purchase of galvanized square pipes. Not only because of the low price, but also because based on the price, there is not much difference in use from hot-dip galvanized steel pipes.

However, it should be noted that if you have a relatively high requirement for the wall thickness of the steel pipe you need, such as requiring a wall thickness of more than 2.5mm. Then the steel pipe manufacturer will default to your request for hot-dip galvanized steel pipes. This is because the raw material of pre-galvanized steel pipe, galvanized strip steel, cannot meet such wall thickness requirements.

That is to say, under the same use conditions, people will use cheaper pre-galvanized steel pipes, and choose hot-dip galvanized steel pipes in special cases. The characteristics of these two types of galvanized steel pipes must be distinguished.
