Characteristics
Most Suitable Suitable
Regular Spangle
Spangle produced by crystallization solidification
Good adhesion and weathering resistance.
Guardrails, ventilation ducts, gutters and down spouts.
Shutter doors, gutters and down spouts, ceiling suspension bars.
Minimized (Zero) Spangle
Blow zinc powder or atomized fog onto the molten zinc layer acts as nucleation sites or control the composition of pot for the minimized spangle.
Uniform surface and attractive finish after painting.
Pre-paint and post paint applications, gutters and down spouts, ceiling suspension bars, shutter door rails.
Automotive parts, guardrails, ventilation ducts.
Extra Smooth Surface
Temper rolling produces an extra smooth surface.
Uniform surface and attractive finish after painting.
Gutter and down spouts, auto parts, electrical appliances, refrigerator appliances, for pre-paint
Automotive parts guardrails, ventilation ducts.
Zinc Coated
Galvannealed
The galvanized strip is heated to alloy the zinc layer.
The zinc-iron alloy coating layer provides good weld ability as well as good corrosion resistance
Shutter doors, signs, automotive parts, vending machines, refrigerators, washing machines, showcases.
Metal furniture, casing for electrical equipment.
5% Al-Zn Coated
Galfan
The Coating alloy comprises about 5% aluminum, mischmetals and balanced zinc.
Good formability excellent paint ability and superior corrosion resistance.
C.Z purlin, gutters, door frame, auto parts, vending machines, guardrails.
Washing machines, for pre-painting applications
55% Al-Zn Coated
Galvalume
The coating alloy comprises about 55% Al, 1.5% Si and balanced zinc.
Uniform and pleasing appearance, good adhesion included.
Gutters, auto parts, electrical appliances, vending machines, refrigerators, ovens, for pre-paint.
Showcases, washing machines, purlin.
