Carbon Galvanized Steel Pipe for Build Agricultural Greenhouse

Carbon Galvanized Steel Pipe for Build Agricultural Greenhouse

Galvanized pipe：

Galvanized pipe, also known as galvanized steel pipe, is divided into hot-dip galvanizing and electro 

galvanizing. The hot-dip galvanizing layer is thick and has the advantages of uniform coating, strong 

adhesion and long service life. The cost of electro galvanizing is low, the surface is not very smooth, 

and its corrosion resistance is much worse than that of hot-dip galvanized pipe.

Production process：
Black parts inspection → hanging → degreasing → rinsing → pickling → cleaning → dipping plating aid → hot air drying 

→ hot dip galvanizing → internal and external blowing → cooling → passivation and rinsing → unloading → inspection and finishing 

→ typing identification → packaging, warehousing and transportation.

Galvanized strip → uncoiling → stretching → rolling pipe → welding → scarring → passivation and rinsing → zinc supplement → setting 

→ typing identification → cutting → packaging → drying → weighing.
