Main features:
Light: the specific gravity of aluminum is 1/3 of steel; so large amounts of main material will be saved if we used it to the roofing or the wall.
Anti-fire: the melting point of aluminum is 660 and it is incombustible.
Mitigate corrosion: the rate of corrosion is only 0.0026mm.
Long service life: it can be used over 20 years.
High strength: its intensity of tension is 15-20kg/mm2.
High returned value: 1/3 of the investment can be regained after used for a long time.
Specification: 0.5---1.5*820*100—20 meters
Pitch of wave: 125mm
Height of wave: 35mm
Thickness: 0.5~1.5mm
Width: 820mm
Length: 2000mm (no limitation of length)
Aluminum can be processed into radian extruded section with radius≥6000mm according to customer's requirement.
Aluminum extruded section should measure up to the regulations of GB6891—86.
