1.Zincalume Slit Coil description
Zincalume Slit Coil is a kind of coated steel. With the cold rolled steel of different strength and thickness as substrate, it is produced through applying Al-Zn coat on both faces by hot dip process. It enjoys both the physical protective feature and durability of Al and the electrochemical protective property of Zn. And its surface has bright silver color and regular embossed-like figure, which are highly decorative.
2.Zincalume Slit Coil technical process
After cleaning and acid pickling, the steel coil is submerged in melted Aluzinc, a chemical reaction permanently bonds the aluzinc. The zinc actually permanently becomes a part of it and the successive
layers are a mixture of aluzinc and iron.
3.Zincalume Slit Coil main usage scope:
1)Architecture roofs and outside walls of civilian and industrial buildings, garage doors, fencings and window blinds
2) Appliances industry outer clad sheets for washing machine, refrigerator, television, air conditioner and ventilation system, explosion-proof strip, solar water heater and appliance parts
3) Auto industry muffler, heat shields of exhaust pipe and catalytic converter, auto parts & accessories under the frame, signboard in highway
4)Industrial instruments electric control cabinet, industrial refrigeration equipment, automatic vending machine
