Hot-dip galvanizing is the reaction of molten metal with an iron substrate to produce an alloy layer, thereby combining the substrate and the plating layer. Hot-dip galvanizing is to pickle iron and steel parts first. In order to remove iron oxide on the surface of iron and steel parts, after pickling, it is cleaned in an ammonium chloride or zinc chloride aqueous solution or a mixed solution of ammonium chloride and zinc chloride.And then sent to the hot-dip plating bath. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.
Hot dip galvanizing (HDGI):it is one of the common galvanizing methods. The process is to completely dip iron or steel into molten zinc.
Electro-galvanizing(EGI):it is to remove the oil, pickle, and then put into the solution of zinc salt by electrolysis equipment, and connect the negative electrode of the electrolysis equipment, place the zinc plate on the opposite side of the pipe fitting, and connect When the positive electrode of the electrolysis device is turned on, a layer of zinc is deposited on the pipe by the directional movement of the current from the positive electrode to the negative electrode, and the cold-plated pipe member is processed and then galvanized.
| Main Features of Products |
01.Anticorrosive:13 years in heavy industrial areas,50 years in the ocean,104 years in the suburbs and 30 years in cities.
02.Cheap:The cost of hot-dip galvanizing is lower than that of other coatings.
03.Reliable:The zinc coating is metallurgically bonded to the steel and forms part of the steel surface,so the coating is more durable.
04.Strong toughness:The galvanized layer forms a special metallurgical structure that can withstand mechanical damage during transportation and use.
05.Comprehensive protection:Every part of the plated piece can be galvanized,and is fully protected even in depressions,sharp corners,and hidden places.
06.Save time and energy:Galvanizing process is faster than other coating methods.
Galvanized Production line
Galvanizing steel production line with annual output of 200000 tons, which
adopts the most advanced American GBNB and Germany's Siemens electrical
control systems. it can produce ZERO zinc spangle, small-zinc spangle and
common zinc spangle etc.Thickness from 0.125 mm to 4.5mm, and width from 500 mm to 1250 mm, and zinc coating from 40 - 275 g/m2, surface passivation and oil-coating can be performed. In addition, the company introduces a slitting machine, which can meet the customers' different requirements on the width.
And Two roll-formed machines , which can produce wave roofing sheet and
Trapezoidal corrugated sheet.
