As the growing area of greenhouses is larger and larger, it means that the number of greenhouses should increase. If the service life of the greenhouse is long enough, the quality of the main steel pipe must be better. Today, I will introduce to you what kinds of greenhouse steel pipes there are.
1. Welded pipe: It is made of steel plate or strip steel as raw materials, first rolled and formed, and then welded. Its main advantages are:
The production process is relatively simple, the production efficiency is high, and the varieties and specifications are diverse. However, its service life is not as good as galvanized pipe.
2, hot dip galvanized steel pipe: the hot dip galvanized steel pipe is carried out in the hot dip plating tank, and the formed coating is more uniform, but also strong adhesion, so it can be used for a long time. Moreover, its corrosion resistance is also very good.
3, galvanized steel pipe: it will be adjusted to get, its price is lower than that of hot-dip galvanized steel pipe, but its corrosion resistance is not as good.
The difference between
hot-dip galvanized steel pipe and galvanized strip steel pipe is as follows:
Difference one: its color, service life, performance and price are completely different, can not be confused.
Difference two: there will be some defects on the surface of hot-dip galvanized steel pipe, such as snowflakes on the surface, zinc nodules on the port, and galvanized steel pipe without
