Product Description

 

ASTM A792 standard AZ150 Galvalume Steel Coil Sheet with Anti Finger Print

 

 

The Plating Coat Of Aluminum - zinc Alloy Armor Plate Is Zn - Al Alloy , And Its Composition Is 55 % Al , 43.4 % Zn And 1.6 % Si . The Plate is of Smooth Surface And Excellent Corrosion Resistance Of The Atmosphere , Which Is 2 To 6 Times Higher Than Hot-Dip Galvanized Sheet Of The Same Thickness Of Plating Coating .

 

After Through Three Processes , Including Payoff Reel , Crop Shear And Welding , Enter Into The Continuous Annealing Furnace . During The Annealing Process , Strips Are Heated Closer To The Recrystallizing Temperature , And Then Heated To 20 - 50 Above The Recrystallizing Temperature In The Reducing Furnace . After Keep The Same Temperature For 170 s , Strips Are Naturally Cooled To The Normal Temperature In The Low Cooling Process . Afterward , Strips Enter Into The Zn - Al Pot Through The Elephant ‘ s Trunk And Begin In The Hot - Dip Coating Process . The Optimum Temperature Rang Of The Plating Coat Is 630 660 . Coated With Aluminium - Zinc Alloy , Strips Enter Into The Cooling Tower By The Steady Roll And Air Knife . After Fast Cooled With Wind Or Water , They Are Directly Produced Into Al - Zn Armor Plates .The General Rate Of Cooling Is 30 / s , And Strips Are Cooled To About 60 .

Characteristics

 

GL are 3 ~ 6 times more corrosion - resistant compared to GI , but has a similar level of processability and weldability and can replace GI, and in particular is most suitable when replacing GI that require thick galvanized layers and high corrosion resistance .

Only galvanized steel sheet that is used for roofing and walls without painting because of its unique silver spangles and beautiful appearance and high - corrosion resistance, and is used as a cool roofing material because of its excellent heat reflection qualities .

Can replace aluminum gilded steel sheets because for certain purposes of its electrical conductivity and its heat-resistance qualities even at high temperatures that do not exceed 315 ℃ .

Has greater surface hardness than GIs , and is much more wear - resistant .

Corrosion resistance increased more with resin-coating treatment , which enables roll forming or press forming without the spraying of processed oils .
