Product Description

Product description

Product Description

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 processingperformance, 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.

Performance characteristics of galvalume

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.

 

Product Application

 

1.Construction: roofs, walls, garages, acoustic walls, pipes and prefabricated houses, etc.
2.Automotive: mufflers, exhaust pipes, wiper accessories, fuel tanks, truck boxes, etc.
3.Home appliances: refrigerator back panel, gas stove, air conditioner, electronic microwave oven, LCD frame, CRT explosion-proof belt, LED backlight, electrical cabinet, etc.
4.Agricultural: pig house, chicken house, granary, greenhouse pipes, etc.
5.Others: heat insulation cover, heat exchanger, dryer, water heater, etc.

 

Precautions for using galvalume sheet

1.Storage: should be stored in the warehouse and other indoor, keep dry and ventilated 1 do not place in acidic climate for a long time. Outdoor storage should prevent rain, to avoid condensation caused by oxidation stains.
2.Transportation: To avoid external impact, the transportation vehicle should be supported by SKID steel coil, reduce stacking and take good rain proof measures.
3.Processing: Coil center shear processing, need to use the same lubricating oil aluminum plate. When drilling or cutting aluminum plated zinc steel plate, the scattered iron filings should be removed in time.

 

The difference between galvalume sheet and galvanized sheet

The difference between galvanized sheet and galvanized sheet:
The difference between the galvanized sheet and the galvanized sheet is mainly the difference in the coating layer. The surface of the galvanized sheet is evenly distributed with a layer of zinc material, which acts as an anodic protection for the base material, that is, an alternative corrosion protection for the zinc material. Without the use of the base metal, 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. Microscopically, the surface of the galvanized coating is a honeycomb structure, and 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, the effect of anodic protection is greatly reduced because the zinc material is wrapped in aluminum and is not easy to be electrolyzed. The galvanized sheet is cut, and it will rust soon when the cut edge basically loses its protection. Therefore, the galvanized sheet should be cut as little as possible. Once cut, the edge should be protected with anti-rust paint or zinc-rich paint to make it The service life of the panels is extended.
