HDGL
Brief Introduction
The HDGL is a kind of coated steel coil/sheet. 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. In its coating, Al accounts for about 55%, Si 1.6%, while
the remaining is Zn. 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.

Application
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
Superiority
1. Resistance to Corrosion Has better performance in corrosion
resistance than hot dip galvanized coil/sheet of the same thickness
and its service life is 1-5 times longer than general hot dip
galvanized coil/sheet.
2. Machinability Can satisfy the processing requirements of
rolling, coiling and others processes alike.
3. Thermal Resistance Can sustain the environment at 315°C for long
time.
4. High Reflectivity Reflection ability of heat and light is twice
as much as those of hot dip galvanized steel coil/sheet, and its
reflectivity is more than 0.75, exceeding 0.65 (required by the EPA
Energy Star Standard), which is an ideal construction material of
saving energy
