Since the galvanized steel plate entered the practical stage in 1972, the global cumulative output has reached 24 million tons, and the annual output is about 3 million tons. 30-35% of the products of galvanized steel sheets are prepainted and used for ceilings, walls, etc. of buildings. In addition to being a trademark of BIEC, galvanized steel sheets are also registered and licensed by BIEC as the following products:
CINCALUM ZALUTITE
ALGAFORT ZINC-ALUM
ALUZINC ZINCALIT
ALUZINK ZINCCALUME
CINCALUM ZINTRO-ALUM
GALVALUME
The surface of the galvanized steel plate has a unique smooth, flat and gorgeous star flower, and the base color is silvery white. The special coating structure makes it have excellent corrosion resistance. The normal service life of the galvanized sheet can reach 25a, the heat resistance is very good, and it can be used in a high temperature environment of 315°C; the adhesion between the coating and the paint film is good, and it has good processing performance, and can be stamped, cut, welded, etc.; The surface conducts electricity very well.
The coating composition is composed of 55% aluminum, 43.4% zinc and 1.6% silicon respectively by weight. The production process of galvanized steel sheet is similar to that of galvanized steel sheet and aluminum-coated sheet, and it is a continuous fusion coating process. Galvalume-coated steel sheets with 55% Al-Zn alloy coating have superior corrosion resistance compared to galvanized steel sheets of the same thickness when both sides are exposed to the same environment. The 55% aluminum-zinc alloy coated galvanized steel sheet not only has good corrosion resistance, but also color-coated products have excellent adhesion and flexibility.

Characteristic:
1. Heat reflectivity:
The heat reflectance of galvanized steel sheet is very high, which is twice that of galvanized steel sheet, and people often use it as a heat insulation material.
2. Heat resistance:
Aluminum-zinc alloy steel plate has good heat resistance and can withstand high temperatures of more than 300 degrees Celsius. It is similar to the high-temperature oxidation resistance of aluminum-plated steel plate. It is often used in chimney pipes, ovens, illuminators and fluorescent lamp shades. Corrosion resistance:
The corrosion resistance of galvalume steel coil is mainly due to the protective function of aluminum. When the zinc is worn away, the aluminum forms a dense layer of aluminum oxide, which prevents the corrosion-resistant substances from further corroding the interior.
3. Economy:
Because the density of 55% AL-Zn is smaller than that of Zn, the area of galvanized steel sheet is more than 3% larger than that of galvanized steel sheet when the weight is the same and the thickness of the gold plating layer is the same.
4. Easy to paint
There is excellent adhesion between the galvanized sheet and the paint, and it can be painted without pretreatment and weathering.
The paint adhesion of the gold-plated layer of galvanized steel is excellent, so it can be directly coated on advertising boards and general-purpose boards without pre-treatment such as weathering.
5. The galvanized steel plate has a gorgeous silver-white surface.
6. The processing performance and spraying performance of galvanized steel sheet and galvanized steel sheet are similar.

Galvalume steel is also called Aluminum-Zinc Alloy Coated Steel, Zinc-alu steel, aluminized zinc steel (aluzinc steel), SGLC, The galvalume metal is composed of 55% aluminium, 43.4% zinc and 1.6% silicon solidified at 600 ~C. Its whole structure consists of aluminium-iron-silicon-zinc, forming a compact quaternary crystal alloy. The surface of the galvalume steel sheet is characterized by smooth, flat and gorgeous stars, and its base color is silver white. The special coating structure makes it have excellent corrosion resistance. The normal service life of galvalume steel sheet is up to 25a, and its heat resistance is good. It can be used in high temperature environment at 315 C. The adhesion between coating and paint film is good, and it has good processing performance. It can be punched, sheared and welded. The surface conductivity is very good.

Advantages

The normal service life of galvalume steel sheet is up to 25a, and its heat resistance is good. It can be used in high temperature environment at 315 C. The adhesion between coating and paint film is good, and it has good processing performance. It can be punched, sheared and welded. The surface conductivity is very good.

Main Features

1.Corrosion resistance:When zinc is abraded, aluminum forms a dense layer of alumina that prevents further corrosion of the corrosive material inside.
2.Heat resistance:Aluminum zinc alloy steel has good heat resistance and can withstand high temperatures of more than 300 degrees Celsius. 3.Thermal reflexes:The heat reflectivity of Al Zn steel plate is very high, which is two times that of galvanized steel sheet.
4.Economical Efficiency:Since the density of 55% AL-Zn is smaller than the density of Zn, the aluminum-zinc-plated steel sheet is more than 3% larger than the area of the plated steel sheet when the weight is the same and the thickness of the gold-plated layer is the same.

We can also produce the Pre-painted galvalume steel coil as customer needs.
