Why are galvanized steel pipes very popular in greenhouses?
As is well known, galvanized steel pipes are coated with a zinc protective layer, which has strong rust prevention protection and higher strength than other steel and iron pipes. The process of galvanizing involves removing iron oxide from the surface of steel pipes through acid washing, and then immersing it in an aqueous solution of zinc chloride or ammonium chloride and zinc chloride, and then immersing it in a molten zinc bath or a zinc rich electrolyte. Zinc reacts with oxygen to form a zinc oxide layer, which further reacts with carbon dioxide to form zinc carbonate to prevent corrosive substances from reaching the steel or iron below.
Galvanized pipes are widely used outdoors and indoors due to their rust resistance. In agricultural production, galvanized steel pipes are increasingly widely used in greenhouses, cultivation, and horticultural frameworks. The greenhouse frame is made of galvanized thin-walled steel pipes, assembled with arch rods, longitudinal rods, membrane grooves, membrane springs, heads, doors, and side ventilation devices.
Lower cost
The greenhouse frame galvanized pipe is made of ordinary carbon steel with hot-dip zinc coating, which is lower in cost than stainless steel. In the long run, it is convenient to use, install, and transport, and there is no need for supporting pipelines inside the shed, which is conducive to mechanized operations.
Long service life
The service life of galvanized steel pipes can reach 15 years. It has strong snow resistance, low thermal conductivity, and good thermal insulation, and will not deform even in cold or hot environments of minus 100 ° C to 60 ° C. Galvanized steel pipes have low maintenance costs, can be inspected with trained eyes, and are easy to assemble.
Good appearance
The additional zinc coating in galvanized pipes ensures a thick and uniform appearance from all sides. Galvanized coatings are different from organic coatings in that small damaged areas do not require modification, and the gray appearance can last for a long time.
Compared with structures made of materials such as bamboo, wood, steel welding, and mixed soil in the past, galvanized steel pipes have significant properties such as high strength, good corrosion resistance, low consumption, convenient installation, and low cost. They have been widely used in the agricultural industry. Please contact us when needed for all galvanized pipes in the greenhouse.
