1. Glass gasket: Rubber substance coped with special solution assures long life and avoids all water penetration
2. Coating: The black chrome plating or selected absorber coating, with high absorptance
3. All-copper absorber: continuity Self-welding All-copper Sun-strip or ultrasonic welding,and higher strenghten and standing higher pressure
4. Disposed special insulation: Reduced the heat-loss and improved the collector's performance.
5. Gasket and sealant
6. Back sheet: galvanized sheet
7. Aluminum alloy frame: Stripy aluminum extrusion article and smooth rubber gasket insures high stability and product the water tightness. This allows easy access to the collector for repaire or maintenance at any time or location
8. Aluminum frame with electrophoresis coating: Good appearance and high anti-corrosion.
