What started editing this paragraph is galvanized steel
Galvanized steel is often applied to daily life is an important alloys. Galvanized steel is aluminum-zinc alloy composition, from 55% aluminum, 43% zinc and 2% of silicon in high temperature 600 ℃ the solidification of the composition, its entire structure consists of aluminum - iron - silicon - zinc, forming dense quaternary crystals an alloy.

1965 Bethlehem (BIEC International Inc) developed and patented in 1972, Bethlehem Steel first U.S. commercial production applicable standards: ASTM A792 / M; JIS G3321; BS EN 10215-1995; GB / T 14978-2008
Edit this section galvanized steel properties
Galvanized steel has many excellent features:
Corrosion resistance:
"Galvanized steel coil," mainly because of the corrosion resistance of aluminum, aluminum protection. When the zinc by the wear and tear, the aluminum will form a dense alumina, to prevent further corrosion resistance to corrosive substances inside.
Heat resistance:
Al-Zn alloy steel sheet has good heat resistance, can withstand temperatures over 300 degrees Celsius, and the aluminum plate is very similar to high temperature oxidation resistance, often used in chimney, oven, hood and fluorescent lighting devices.
Heat reflective:
Galvanized steel high rate of heat-reflective, galvanized steel is twice that, people often use it as insulation material.
Economy:
Because 55% AL-Zn and Zn density than the density of small, so the same weight and thickness of the gold layer under the same conditions, galvanized steel galvanized steel than the area more than 3%.

Use
Building: stone coated steel roof, walls, garage, noise walls, pipes and modular housing car: muffler, exhaust pipes, wiper accessories, fuel tank, truck boxes and other home appliances: refrigerator back, gas stove, air conditioner, electronic microwave oven, LCD frame , CRT with explosion-proof, LED backlight, electrical cabinets and other farm: barns, sheds, silos, piping and other greenhouse: Heat insulation cover, heat exchangers, dryers, warm water, etc.
Caution
Care: should the Treasury and other indoor storage, dry air, not in the acidic climate in the long home. Outdoor storage is required to prevent the rain, to avoid condensation resulting in oxidation of stain produced. Transportation: Avoid external impact, means of transport required SKID supporting coil, reducing stacking, good rain measures. Processing: COILCENTER shear processing, use the same aluminum oil. Need drilling or cutting galvanized steel, the need for timely clean up scattered iron filings.
