Hot-dip galvanizing (HDG), as referenced is the process of dipping fabricated steel into a kettle or vat of molten zinc. While the steel is in the kettle, the iron metallurgically reacts with the molten zinc to form a tightly-bonded alloy coating that provides superior corrosion protection to the steel.
Type: ERW (Electric Resistance Welding) Construction Hot-Dipped Galvanized Steel Pipes
Applications:
Construction of fences for houses, residential areas, industrial areas, warehouses, agricultural areas, public areas (ports, airports, jails, refugee camps, electricity substations, etc), photovoltaic solar parks, fences NATO type, etc
Industrial applications
Structures (scaffolds, tents, shelters, parking, etc)
Construction of greenhouses
Construction of road signs
Quality:
The steel grade is ST 37-2 according to DIN 17100. The zinc coating is according to DIN 2444 with minimum coating thickness 400 g/m2.
Packing:
In bundles of hexagonal type, 37 or 61 or 91 pipes strapped together (depending on the size) with 5 straps and 2 slings per bundle for easy loading – unloading
Wall Thickness is from 1.80 mm up to 4.00 mm (the most popular wall thickness is the 2.00 mm)
Length of the pipes is from 2.50 m up to 7.00 m (the most popular lengths are the 5 m, 6 m & 6.60 m), with tolerance -0+50 mm
After agreement, there is possibility for production of different sizes (wall thickness & length)
Sales per bundles and also per single pipe

What are the advantages of hot dipped galvanized steel pipe?
Hot galvanized steel pipe is widely used in construction, machinery, coal, chemical, railway vehicles, automobile industry, highway, bridge, container, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery and other manufacturing industries.
Galvanized steel pipe surface is hot dip galvanized or galvanized layer of welded steel pipe. Galvanized steel pipe can increase the corrosion resistance, extend the service life. Galvanized pipe is widely used, in addition to water, gas, oil and other general low-pressure fluid pipeline, but also for the oil industry, especially offshore oil wells, oil pipe, chemical coking equipment, oil heater, condensation Cooler, coal waste detergent oil pipe, and the bridge piles, mine tunnel support tube and so on.
The hot-dip galvanizing pipe is a method in which a molten metal is reacted with an iron matrix to produce an alloy layer, so that both the substrate and the plating layer are combined. Hot-dip galvanizing is the first pickling of the steel pipe, in order to remove the iron oxide surface of the steel pipe, pickled, through ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed water tank cleaning, and then into Hot dip bath. Hot galvanized with uniform coating, strong adhesion, long life and other advantages. Hot-dip galvanized steel pipe matrix and molten bath complex physical and chemical reactions, the formation of corrosion-resistant structure of a close zinc alloy layer. Alloy layer and pure zinc layer, steel pipe body integration. So its strong corrosion resistance.
