Why Are The Galvanized Steel Pipes Popular In Greenhouse?

As we know, the galvanized steel pipe has been coated with a protective layer of zinc which provide strong protection against rust and more strength than other steel and iron tubing. The process of galvanizing is to remove the iron oxide from the surface of the steel tube by pickling, then putting it into an aqueous solution of zinc chloride or an aqueous solution of ammonium chloride and zinc chloride, and then dipping it into a bath of molten zinc, or a zinc-rich electrolyte. The zinc reacts with oxygen to create zinc oxide layer that further reacts with carbon dioxide to create zinc carbonate to prevents corrosive substances from reaching the underlying steel or iron.

The galvanized pipe was been widely used in outdoor and indoor applications due to its anti-rusting performance. In agricultural production, galvanized steel pipe is more and more widely used in greenhouse, cultivation and horticultural frame. The frame of the greenhouse is made of galvanized thin-walled steel pipe, which is assembled together with the arch rod, longitudinal bar, film slot, film spring, roof head, door and side ventilation device.

 

LOWER COST

Galvanized pipe for greenhouses frame is made by plain carbon steel with hot dipped zine coating, low cost than stainless steel. In the long run, it’s easy to use, installation and transportation, no need for supporting pipe in the shed, conducive to mechanized operation.

 

LONG LIFESPAN

The service life of galvanized steel pipe can be up to 15 years. It offers strong snow resistance, low thermal conductivity, good heat insulation, without deformation under the environment of the harp cold or hot even 100℃ to 60℃ below zero. The galvanized steel pipes are low maintenance, can be inspected with a trained eye and are easily assembled.

 

GOOD APPEARANCE

The extra coating of the zinc in the galvanized pipe ensures the thick and uniform appearance from all side. Galvanized coatings unlike organic coatings, small damaged areas need no touch up, gray appearance can be last long time.

 

Compared with the previous structural made by bamboo and wood, steel welding, mixed soil and other materials, galvanized steel tube is characterized by its high strength, good corrosion resistance, less consumption, easy installation, low cost and other significant performance, has been widely used in the agriculture industry.
