As we know galvanized steel pipes have been coated with a protective layer of zinc which provides greater rust resistance and strength than other steel and iron pipes. The process of galvanizing is to pickle the iron oxide on the surface of the steel pipe, then turn it into a zinc chloride aqueous solution or an ammonium chloride and zinc chloride aqueous solution, and then dip it into a bath of molten zinc, or a zinc-rich electrolyte. Zinc reacts with oxygen to form a zinc oxide layer, which reacts with carbon dioxide to form zinc carbonate, preventing corrosive substances from reaching the steel below.

Galvanized pipes are widely used both indoors and outdoors due to their good anti-rust properties. In agricultural production, galvanized steel pipes are increasingly used in greenhouses, cultivation and horticulture frames. The frame of the greenhouse is made of galvanized thin-walled steel pipes, assembled with arch rods, longitudinal rods, membrane troughs, membrane springs, heads, doors, and side ventilation devices.
lower cost
The galvanized pipe greenhouse frame is made of hot-dip galvanized carbon steel, which is lower in cost than stainless steel. In the long run, it is easy to use, install and transport, and does not require supporting pipelines in the shed, which is conducive to mechanized operation.
long life
The service life of galvanized steel pipes can be up to 15 years. It has strong snow resistance, low thermal conductivity and good thermal insulation performance. It will not deform in the hot and cold environment of the harp, even at minus 100°C to 60°C. Galvanized steel pipe is low maintenance, can be inspected by a trained eye, and is easy to assemble.
good appearance
The additional layer of galvanized steel inside the galvanized pipe ensures that the appearance of the galvanized pipe is thick and uniform from all sides. Galvanized coatings differ from organic coatings in that small damaged areas do not need to be repaired and the gray appearance is long-lasting.
Compared with previous structures made of bamboo, wood, steel welding, concrete and other materials, galvanized steel pipes have significant properties such as high strength, good corrosion resistance, low consumption, easy installation, and low cost. They have gained popularity in the agricultural industry. Wide range of applications. If you need galvanized pipes for your green greenhouse, please contact us.
