Product Description

Product Description

Galvanizing coil is a thin steel sheet dipped into a molten zinc tank to make its surface adhere to a layer of zinc.The main use of continuous galvanized process production, that is, the roll of steel plate continuous dip in the melting zinc plating tank made of galvanized steel.

Galvanized coil has the characteristics of strong corrosion resistance and good surface quality, and is widely used in construction, home appliances, automobiles, containers, transportation and other fields.

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.
Surface treatment of galvanized coils
1. Passivation C
2. Oil O
3. Lacquer seal L
4. Phosphating P
5. Do not process U

1 passivation
The galvanized layer is passivated to reduce folding corrosion (white rust) under tidal temperature storage and transportation conditions. However, the anti-corrosion performance of this chemical treatment is limited and, moreover, hinders the adhesion of most paints. This kind of treatment is generally not used in the zinc-iron alloy coating. Except for the smooth surface, as a routine, the manufacturer conducts passivation treatment on other types of zinc coating.
2 oiled
Oiling can reduce steel plate corrosion under wet storage and transportation conditions, and re-oiling steel plates and steel strips after passivation treatment will further reduce corrosion under wet storage conditions. The oil layer should be able to be removed with a degreasing agent that does not damage the zinc layer.
3 paint seal
An additional corrosion protection, especially anti-fingerprint properties, can be provided by applying a very thin film of transparent organic coating. Improves lubricity when forming and acts as an adhesion primer for subsequent coats.
4 Phosphating
Through phosphating treatment, galvanized steel sheets of various coating types can be coated without further treatment except for normal cleaning. This treatment can improve the adhesion and anti-corrosion performance of the coating, and reduce the risk of corrosion during storage and transportation. After phosphating, it can be used with a suitable lubricant to improve the forming performance.
not deal with
The steel plates and strips supplied according to this standard may not be passivated or oiled or painted or phosphating and other surface treatments are required only if the orderer puts forward a request not to be treated and is responsible for it.


Product Advantages
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 coils can be divided into hot-rolled galvanized coils and cold-rolled hot-dip galvanized coils. They are mainly used in construction, home appliances, automobiles, containers, transportation and household industries. Especially industries such as steel structure construction, automobile manufacturing, and steel warehouse manufacturing.
