DX51D+AZ Galvalume Steel Coil
Product Description
Galvalume coil is a kind of aluminum-plated zinc alloy treatment method to form a coil with high strength, excellent corrosion resistance and beautiful appearance on the surface of steel, with high corrosion resistance and air pollution resistance. Galvalume coil also has good surface decoration, and can be processed into a variety of beautiful building and home appliance materials.
The production process of aluminum zinc plating is as follows:
Uncoiling-cleaning-annealing-zinc pot-cooling-air knife-straightening-post-treatment-coiling
Heat Reflection
People use it as a thermal insulation material, and its thermal reflectivity is up to twice that of galvanized steel.
Heat Resistance
Galvanized steel coil has good heat resistance and can withstand high temperatures above 300°C, which is very similar to the oxidation resistance of aluminized steel at high temperatures. Commonly used in chimney tubes, ovens, illuminators, fluorescent lampshades, etc.
Corrosion Resistance
The key to the corrosion resistance of aluminized zinc steel coil is the protective performance of aluminum. Once the zinc is worn, the aluminum forms a dense layer of aluminum oxide, preventing further internal corrosion.
Economy
The density of 55% AL-Zn is smaller than that of Zn. Therefore, when the coating weight and thickness are the same, the area of the aluminum-zinc plated steel sheet is 3% larger than that of the galvanized steel sheet.
Easy to Paint
The coating material on the aluminized zinc steel plate has excellent adhesion, and can be directly coated with tar on advertising boards and common plates without pretreatment such as weathering.

Common alloying ingredients include chromium (usually at least 11%), nickel, or molybdenum. Alloy content often is on the order of 15-30%.
Common applications for stainless steel include food handling/processing, medical instruments, hardware, appliances, and structural/architectural uses.![201 Stainless Steel Strip]( "201 Stainless Steel Strip")
201 Stainless Steel StripStainless steel strip is an extension of ultra-thin stainless steel plate, and is also a kind of steel plate used in industry. However, unlike ordinary steel plates, stainless steel strip has a longer shape, and its scope of use is also different from ordinary steel plates. At present, there are many varieties of stainless steel strips, and there are also many different production specifications. Different stainless steel strips use different categories. Cold rolled strip is a specially treated stainless steel strip product. It is another industrial steel strip product, which is made of stainless steel strip as the basic material and is processed by cold rolling mill at room temperature. The rolled strip has excellent characteristics such as smooth surface, flatness, high dimensional accuracy and good mechanical functions, and is often processed into rolls and coated steel plates. Cold rolled strip is widely used in tractor, car and other industrial manufacturing. Hot rolled strip is another kind of stainless steel strip, which has low hardness, easy processing, good ductility and other excellent characteristics, so it is often used as a thin plate.![Q235 Carbon Steel Plate]( "Q235 Carbon Steel Plate")
Q235 Carbon Steel PlateCarbon steel, on the other hand, has far lower chromium levels, and is instead a carbon-iron alloy with only a few other materials, if any, as part of its makeup. As a result, it can be referred to as ‘low-alloy’ steel. Both stainless steel and carbon steel feature this basic composition, but carbon steel can be defined by its carbon content. This is normally around 2-2.5%, however this often varies. Though susceptible to rust unlike stainless steel, carbon steel is often cheaper and has its own varying mechanical properties based on carbon content.![ASTM A36 Carbon steel bar/rod]( "ASTM A36 Carbon steel bar/rod")
