material classification of galvanized sheet

The material of galvanized sheet introduced galvanized sheet

1, hot dip galvanized steel plate. The sheet steel is dipped into the melted zinc tank so that the surface is adhered to a zinc sheet steel. At present, continuous galvanizing process is mainly used to produce, that is, continuous immersion of rolled steel plate in the melting of zinc in the plating tank to make galvanized steel plate;

2, alloyed galvanized steel plate. This steel plate is also made by hot dipping, but immediately after it is out of the groove, it is heated to about 500℃ to produce a zinc and iron alloy film. This galvanized sheet has good coating tightness and weldability;

3, electric galvanized steel plate. The galvanized steel plate made by electroplating has good workability. But the coating is thin, corrosion resistance is not as good as hot dip galvanized sheet;

4, single-side plating and double-side difference galvanized steel plate. Single-sided galvanized steel plate, that is, galvanized products only on one side. It has better adaptability than double-sided galvanized sheet in welding, coating, rust prevention and processing. In order to overcome the shortcomings of single side without zinc coating, there is a galvanized sheet coated with a thin layer of zinc on the other side, namely double-sided differential galvanized sheet;

5, alloy, composite galvanized steel plate. It is made of zinc and other metals such as aluminum, lead, zinc alloy and composite plating of steel plate. The steel plate not only has excellent anti-rust performance, but also has good coating performance;

6. In addition to the above five kinds, there are color galvanized steel plate, printing coated galvanized steel plate, PVC laminated galvanized steel plate and so on. But at present the most commonly used is still hot dip galvanized sheet.

What is the material of galvanized sheet?

Galvanized sheet belongs to steel. The so-called galvanized plate is a layer of zinc plated on the surface of the steel plate, which can prevent the corrosion of the steel plate, play a protective role, so as to increase its service life. According to different processing methods, it can be divided into hot dip galvanized steel plate, color galvanized steel plate, electric galvanized steel plate, single and double difference galvanized steel plate, alloyed galvanized steel plate, printing coated galvanized steel plate, alloy galvanized steel plate and so on.

Galvanized plate action

Galvanized coil is hot-rolled steel strip or cold-rolled steel strip as the base plate, after continuous hot-dip galvanized process and produced, the product has strong corrosion resistance, good surface quality, conducive to deep processing, economic and practical characteristics, used as the substrate of downstream products, construction industry: Light steel keel, corrugated board, ventilation pipe, floor bearing board, mobile house, factory roof, house body, municipal engineering enclosure board, etc.

Home appliance industry, air conditioner, refrigerator, washing machine, microwave oven, water heater, computer case, solar energy and other home appliance products shell and bottom plate, automobile industry: car body, outer plate, inner plate, bottom plate, door, etc., furniture industry: Wardrobes, tables, nightstands, filing cabinets, filing cabinets, bookshelves and other types of furniture guide, other industries, storage, packaging, granaries, chimneys, buckets, rosin barrels, galvanized pipes, beer fermentation tanks, distribution cabinets, containers, fertilization boxes and so on.

What is the material of galvanized sheet?

Galvanized plate, which is a layer of zinc plated on the surface of the steel plate, which can play a role in corrosion protection, this method consumes nearly half of the world's zinc. Galvanized sheet uses a special process, the use of technology and processing methods are different, the production of galvanized sheet is not the same; There are also certain differences in the raw materials used in different galvanized sheets. Its classification is very much and its use is also very wide. Next, let's understand what the material of galvanized sheet is, and what classification it has.

Material and application of galvanized sheet:

1. Non-alloy hot dip galvanized steel strip

DC5XD series: Can be used for general use, also can be used for deep punch, bite. The higher the zinc content on the surface, the better the corrosion resistance; The less the surface galvanized, the better the processing performance.

SXXXGD series: Can be used for structure, it has good machining performance and corrosion resistance.

HXXXPD+Z series: including low alloy steel, phosphorous steel and hardened steel, it has superior workability and corrosion resistance.

2. Alloyed hot-dip galvanized steel strip

DCXXD+ZF series: can be used for structure, stamping and cold forming. This kind of galvanized sheet has better welding performance and coating performance, but it is very easy to produce peeling in the process of processing.

Galvanized sheet classification introduction:

1. Alloyed galvanized steel plate: The steel plate produced by hot dipping method has good weldability and tight performance.

2. Hot gold galvanized steel plate: this is a thin layer of zinc attached to the surface of the thin steel plate, its production process is continuous galvanized.

3. Electric galvanized steel plate: the way of galvanizing steel plate, but this way of zinc plating is thin, corrosion resistance is poor.

4. Single-side galvanized steel plate: only on one side of the steel plate zinc plating, whether used for processing, painting or welding, adaptability is better than double-sided zinc plating steel plate.

5. Double-sided galvanized steel plate: single-sided galvanized steel plate still has some shortcomings, in order to overcome these shortcomings, will also be on the other side of the steel plate plated with a thin layer of zinc, this is double-sided galvanized steel plate.

6. Composite galvanized steel plate: in addition to pure steel, the internal material is made of lead, aluminum and other metal composite steel plate, and then a layer of zinc plating on the surface. This kind of steel plate rust resistance is more superior, coating performance is also better.
