Features and application of galvanized sheet

 Galvanized sheet features:

1. Heat reflection:

The thermal transmittance of galvanized sheet is very high, which is twice that of galvanized sheet. It is often used as a raw material for thermal insulation.

2. Temperature resistance:

Galvanized sheet has excellent temperature resistance, can withstand high temperatures of more than 300 degrees Celsius, and is similar to the high-temperature reduction resistance of aluminized thick steel plates. Corrosion resistance

根本 The root cause of the corrosion resistance of galvanized sheet is the maintenance effect of aluminum. When zinc is damaged, aluminum produces a layer of high-density aluminum trioxide, preventing further corrosion of the interior by corrosion-resistant chemicals.

3. Reasonability:

Since the relative density of 55% AL-Zn is smaller than the relative density of Zn, the total area of ​​galvanized sheet is about 3% larger than that of galvanized sheet under the same net weight and the same thickness of the plating layer.

4. Easy to paint

出色 Excellent adhesion between galvanized sheet and paint, it can be painted without pretreatment and weathering. Architectural coatings of aluminum-zinc plate and thick steel plate have excellent adhesion. Therefore, they have not been solved by Weathering, and can be immediately applied to advertising boards and general boards.

5. Galvanized sheet has a beautiful silver surface.

6. Galvanized sheet and galvanized sheet have similar production and processing characteristics and painting characteristics.

运用 Application of galvanized sheet:

Engineering and construction: roofs, walls, parking spaces, sound insulation panels, pipes and combined houses, etc.

Car: silencer, exhaust pipe, wiper notes, fuel tank, large truck box, etc.

Household appliances: refrigerator side panels, gas stoves, air conditioners, electronic device microwave oven heating, LCD frames, CRT explosion-proof belts, LED backlights, electrical cabinets and other agricultural vehicles: pig pens, chicken sheds, grain depots, greenhouse greenhouse tubes Road etc

Others: thermal insulation cover for broken window insulation window, heat exchanger, air dryer, warm water heater, etc.
