Curved Solid Aluminum sheet is used aluminum or aluminum alloy as
the raw material, the processing of molding and decorative surface
protective and decorative coating of architectural aluminum
cladding. The use of internationally renowned brands of the United
States PPG, Japan's state legislature fluorocarbon coating company,
the PVDF content of not less than 70 percent, to ensure that the
color and durability of excellent quality. Our production of
fluorocarbon liquid sprayed aluminum sheet by the State Building
Materials Quality Supervision and Inspection Center testing,
product performance in full compliance with "building decorative
aluminum sheet," the national standards.
