PRODUCT DESCRIPTION

Product Description

Galvanized steel sheet is a registered trademark of BIEC International Inc., which is one of the world patents of BIEC. 31 steel mills in 22 countries around the world have obtained production technology and licenses from BIEC International, and are producing galvanized steel sheets with a surface coating of 55% aluminum-zinc alloy.

The surface of the galvanized steel sheet has a unique smooth, flat and gorgeous star flower, and the base color is silver 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, which can be punched, sheared, welded, etc.; The surface conductivity is very good.
The coating composition consists 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 aluminized sheet, and it is a continuous molten coating process. The galvanized steel sheet with 55% Al-Zn alloy coating has superior corrosion resistance compared with the galvanized steel sheet of the same thickness when both sides are exposed to the same environment. The galvanized steel sheet with 55% aluminum-zinc alloy coating not only has good corrosion resistance, but also the color-coated products have excellent adhesion and flexibility.

choose

Since the steel plate will be oxidized and rusted when it is wet, it is necessary to add an anti-corrosion protective layer on the surface. , zinc 43.5% and silicon 1.5%, referred to as 55% Al-Zn). According to the data, the comprehensive anti-corrosion ability of 55% galvanized zinc is 4 times that of galvanized with the same thickness.
According to foreign experience and specifications, the anti-corrosion coating of the base material of general profiled steel plate (pit plate) should not be less than hot-dip galvanized 350g/㎡ (Z35) or hot-dip galvanized 185 g/㎡ (AZ185) as the building structure cooling The minimum Zinc/Galvanizing specification of hot-dip galvanized layer for rolled steel and floor slab is 275 g/㎡ (Z27), and the requirement for coastal exposed parts is 350 g/㎡ (Z35).

characteristic

1. Heat reflectivity:
The heat reflectivity of galvanized steel sheet is very high, twice that of galvanized steel sheet, and people often use it as a thermal insulation material.
2. Heat resistance:
Al-Zn alloy steel plate has good heat resistance and can withstand high temperature of more than 300 degrees Celsius, which is very similar to the high temperature oxidation resistance of aluminized steel plate, and is often used in chimney pipes, ovens, luminaires and fluorescent lamp shades . Corrosion resistance:
The corrosion resistance of galvanized steel coil is mainly due to the protective function of aluminum and aluminum. When the zinc is worn away, the aluminum forms a dense layer of aluminum oxide, preventing 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 the galvanized steel sheet is more than 3% larger than that of the galvanized steel sheet under the same weight and the same thickness of the gold-plated layer.
4. Easy to paint The
galvanized sheet and the paint have excellent adhesion, and can be painted without pretreatment and weathering treatment.
The coating adhesion of the gold-plated layer of galvanized steel sheet is relatively good, so it can be directly coated on advertising boards and general-purpose boards without pre-treatment such as Weathering.

5. Galvanized steel sheet has a gorgeous surface of silvery white.

6. Galvanized steel sheet and galvanized steel sheet have similar processing performance and spraying performance.

The difference between galvanized sheet and galvanized sheet:
The difference between galvanized sheet and galvanized sheet is mainly in the difference of coating. The surface of galvanized sheet is evenly distributed with a layer of zinc material, which plays an anodic protection role for the base metal. , that is to say, the alternative corrosion of the zinc material protects the use of the base metal, and only when the zinc is completely corroded can the base metal inside be damaged.
The surface coating of the galvanized sheet is composed of 55% aluminum, 43.5% zinc and a small amount of other elements. The surface of the galvanized coating is a honeycomb structure at the microscopic level. The "honeycomb" composed of aluminum contains zinc. In this case, although the aluminum-zinc coating also plays the role of anodic protection, on the one hand, due to the reduction of zinc content, on the other hand, because the zinc material is not easily electrolyzed by aluminum, the role of anodic protection is greatly reduced. The zinc plate is cut, and it will rust quickly when the cut edge is basically lost and protected, so the galvanized plate should be cut as little as possible. The service life of the board is extended.
