After degreasing treatment of steel strip made from cold rolling machine line ,steel strip is sent to continuous hot zinc galvanized machine line for the following processing:

1. annealed in annealing furnace.

2. hot dipped and zinc galvanized in molten zinc.

3. passivation or polishing

4. elongation and leveling

All the processing above constitute necessary manufacturing steps of hot zinc galvanized steel plate.

Hot zinc galvanized steel plate increasingly applies to apparatus, automotive , machines in office ,furniture and architecture.

2、Electroplated zinc steel:

Electroplated zinc steel coil

Electroplated zinc steel

Electrogalvanizing is the process of forming a uniform, dense, and well bonded zinc coating on the surface of a workpiece using the principle of electrolysis. The advantages are as follows:

1. Electroplated zinc can form a layer of zinc on the metal surface, which has good corrosion resistance and can effectively prevent corrosion and rust on the metal surface.

2. Electrogalvanizing can increase the hardness of the metal surface, making it more wear-resistant and durable.

3. Electrogalvanizing can make the metal surface smoother and brighter, improving its aesthetic level.

4. The galvanizing process is pollution-free and does not cause harm to the environment. The cost of galvanizing is relatively low, which can effectively reduce production costs.

In summary, galvanizing has a wide range of applications and has advantages such as good corrosion resistance, wear resistance, aesthetics, environmental friendliness, and economy. It is a very practical metal surface treatment process.

Pre-Painted Steel

Prepainted galvanized steel coil

In the continuous processing machine, cold rolled steel sheet and zinc galvanized steel sheet served as basal plate, one layer or several layers of liquid paint are painted onto the basal plate after surface pretreatment. Steel sheet is changed into coated steel sheet after baking and cooling. As the layer bears different colors, thus coated steel sheet is also known as color coated steel sheet. Besides, because painting is preceded prior to the formation processing, coated steel sheet is also called as pre-coated steel sheet. .In this processing ,traditionally adopted spraying is replaced by continuous painting, which is conducive to surface treatment ,quality control of coating layer and avoid defects in edges.

Application of color coated steel sheet:

Outdoor: roof, roof structure, surface sheet of balcony, frame of window, door, door of garage, roller shutter door, booth, Persian blinds, cabana, refrigerated wagon and so on. Indoor: door, isolater, frame of door, light steel structure of house, sliding door, folding screen, ceiling, internal decoration of toilet and elevator.

Application in apparatus:

Refrigerator, refrigerated wagon, washing machine, electric baker, automatic selling machine, air conditioner, copying machine, cabinet, electric fan, vacuum sweeper and so on.

Application in transportation:

Ceiling of automobile, board, internal decoration board, external shelf of automobile, carriage board, car ,instrument panel, shelf of operating platform, trolley bus, ceiling of railway, color isolator of ship, furniture of ship, floor, cargo container and so on.

Application in furniture and sheet metal processing:

Electric warming oven, shelf of water heater, counter, shelves, chest of drawers ,chair, archive cabinet, book shelves.

Galvalume Steel

Product Description:

Galvolume/Galfan products (GL) use cold rolled steel sheets with various strengths and thicknesses as the raw materials and are coated with aluminum (Al 55%), zinc (Zn 43.5%) and silicon (Si 1.5%) alloy. It possesses excellent anti-corrosion properties.

Product Features:

Derived from hot-dip aluminum galvanization and hot-dip zinc galvanization technology, Galvolume/Galfan products possess excellent properties of both products, i.e. the exceptional anti-corrosion and anti-oxidation properties of hot-dip aluminum galvanization, and superior electric-chemical properties of hot-dip zinc galvanization, which make Galvolume/Galfan sheets less prone to rust and corrosion at the edge and on the scratched surface. The major properties of Galvolume/Galfan steel sheets include the following:

(1) Smooth surface and superior anti-corrosion property. They can resist corrosion up to 2 to 6 times longer than hot-dip zinc galvanized steel sheets;

(2) Excellent heat resistance and anti-oxidation properties. They will not tarnish under 300℃ and can be used normally under 500℃ for a long time. They can resist corrosion caused by water and mud. Its ability to resist corrosion caused by water is better than that of hot dip aluminum galvanization, and its ability to resist corrosion caused by mud is better than that of hot-dip zinc galvanization. They are the ideal materials for auto mufflers, exhaust pipes, food dryers, water heaters, etc. In addition, its heat reflection ratio exceeds 75% and is twice as high as zinc galvanized steel sheets;

(3) Excellent properties for being coated and processed. They are highly adhesive to organic color coatings. Its processed and welded properties are similar to those of zinc galvanized steel sheets. They can be bent and pressed while maintaining exceptionally beautiful appearance. Since aluminum is lighter than zinc (the density of aluminum and zinc galvanization is 3.7kg/dm3 as compared with 7.1kg/dm3 for zinc galvanization), for galvanization of the same thickness, aluminum and zinc galvanization reduces the amount of metal used and hence results in cost savings.
