a. advanced equipments: Our company has introduced italy technologies, cooperated with domestic mechanical field, and adopted at present the firenew equipment of this field, such as fire-new liquid expanding equipment, trunk connecting water pipe digitally controlled process machine and full automatic copper-aluminum compound radiator soldering machine.

b. scientific and precise choice materials: copper pipes adopt TP2 phosphorized copper, and wall thickness of column & channel are in accordance with global standard (GB/T18033-2000 seamless copper water tube & copper air tube). All water tubes adopt pure red copper (Gu+Ag≥99, ingredient of impurity≤0.01 ). With advanced technology, weld strength is up to 5.0Mpa, and all the windiya radiators has processed by second stike so that they have a test pressure bearing capability of 1.6Mpa.

c. appearance: appearance adopts static electricity spraying and doping processes, and coating is solidified with high temperature of 200℃, thus the coating endure, smooth and nondiscolouring. Colorful appearance combines with fitment style perfectly.

d. pure copper water pipe: they have realized the breakthrough in the structure,and with anti-alkalescence, anti-oxizide, antisepsis, and applicablity to various water conditions, their lifetime can make up to 50 years.
