Product Details

Product Description
Aluminized zinc steel sheet is an alloy coated steel sheet with the best combination of aluminum and zinc composition and structure. It has the corrosion resistance of aluminum, heat resistance and the electrochemical properties of zinc, and the surface is uniquely smooth, flat and gorgeous spangles , The base color is silver gray: the coating composition is composed of 55% aluminum, 43.4% zinc and 1.6% silicon in weight ratio.
Basic Characteristics
Weight ratio:
55%A1 43.4%Zn 1.6%Si
Volume ratio:
80%A1 18.0‰Zn 2.0‰Si
Density:
3.75g/cm3
Melting point:
590℃
Hardness:
120~159(MHV)
Surface:
silver gray, uniform cobalt stone spangles
The role of aluminum, zinc, silicon
Aluminum, zinc :

A1<5%, A1↑→Corrosion resistance↑
5%~25%, A1↑→Corrosion resistance↓
A1>55%, the corrosion resistance is not significantly weakened, but some pitting corrosion appears. 55% A1 is the best and 25% A1 is the worst.
Silicon:
1. Inhibit the reaction between the steel strip and the bath melt
2. Inhibit the growth of aluminum-rich dendrites and improve the ability to resist peeling 3. "Heterogeneous nucleation"" to refine spangles 4. Reduce the viscosity of the plating solution and reduce the thickness of the alloy layer 5. Speed up the dissolution rate of the alloy layer

Product advantages
①Good corrosion resistance Under various environmental conditions, the galvanized steel sheet has excellent corrosion resistance than the hot-dip galvanized steel sheet of the same thickness, and its service life is 2-6 times that of the ordinary galvanized steel sheet. Since the microcracks of the aluminum-zinc-plated deformed parts are smaller than that of the hot-dip galvanizing, the corrosion resistance in the forming area is much higher than that of the hot-dip galvanizing.
②Good surface characteristics The surface characteristics are good, the spangles are small and uniform, the color is bright silver gray, and the surface hardness is high (not easy to scratch). ③Good processability The 55% aluminum-zinc alloy coated galvanized steel sheet has excellent adhesion and flexibility. It has excellent shape and workability similar to galvanized steel sheet. Especially, there are few cracks in the processing part on the steel sheet, and the durability of the processing part is excellent . ④Good heat resistance The heat resistance of galvanized steel sheet is much better than that of galvanized steel sheet, and has the characteristics similar to that of aluminized steel sheet: Galvanized steel: It is recommended not to exceed 230℃ at high temperature, it will change color if it exceeds 250℃. Galvalume steel: The color does not change even when used for a long time at around 315℃, and it can also be used at around 370℃ for a short time. ⑤Good heat reflection The heat reflectivity of steel plate is about twice higher than that of galvanized steel plate, so when uncoated products are used on roof and partition wall panels, better energy saving effect can be obtained.

⑥Good coating performance When the galvanized sheet is used as a writing board or other purposes for painting, it only needs to be degreasing without pretreatment or etching treatment. The reason is that the coating and the coating have a good polarity combination, and the hot-dip galvanized layer It won't work. ⑦ Relatively light weight Due to the light weight of the galvanized steel plate, under the same coating thickness, the unfolded area of ton steel is larger than that of galvanized steel. Take 0.48m and 40μm coating (both sides) as an example, its weight per square and ton of steel can be unfolded The area is as follows:
Substrate: AZ150 Z275; AZ150 Z275 Weight per square meter: 3.94kg 4.06kg Expandable area: 254m2 246m2
Post-processing
-Passivation treatment :Chromated -Anti-finger printed: Anti-finger printed -Oiled treatment :0iled
