China 3.2mm Cheap Aluminum Alloy Sheet Solar Mirror for Super Reactivity Heliostat

Product Description

Solar mirror is a reflective surface used for gathering an reflecting solar energy in a system being powered by solar energy it comprices a glass substrate,a reflective layer for reflecting the solar energy,and an interference layer. The purprose of the solar mirror is to achieve a substantially concentrated reflection factor for solar energy systems.

Features:

1)Made of quality low iron extra clear glass

2)thickness:1.1mm, 3mm, 3.2mm or 4mm.

3)Silver coated with copper, 3 layers of protective back paints

4)Water-resistance 5)Scratch-resistance

5) Anti-UV

6) Can bear complex climate environment

7) Can be used at least 20 years

Thickness:1.1mm / 3.0mm /3.2mm/4.0mm
