coil

COIL

These coils serve as the primary materials for building constructions, including roofing sheets, decorations, and wall panels, comprising both aluminum and steel variants. Surface treatments encompass mill finish, galvanized, galvalume, colorful painted, wrinkle, and smooth finishes, supporting special pattern customizations, thus offering a wide array of choices.

The difference between galvanized coil and galvalume coil mainly lies in the difference of coating.

The surface of galvanized coil is evenly distributed with a layer of zinc material, which plays the role of anode protection for the base material;the surface coating of galvalume coil is composed of 55% aluminum, 43.5% zinc and a small amount of other elements.

The surface of the galvalume coating is a honeycomb structure at the micro level, and the “honeycomb” composed of alu-zinc contains zinc.

  • Construction: roofs, garages, walls, pipes and modular houses
  • Automobile: muffler, exhaust pipe, wiper accessories, fuel tank, truck box, etc
  • Home appliances: refrigerator backboard, gas stove, air conditioner, electronic microwave oven, LCD frame, CRT explosion-proof belt, LED backlight, electrical cabinet, etc
  • Agricultural use: piggery, chicken coop, granary, greenhouse pipes, etc
  • Other: heat insulation cover, heat exchanger, dryer, water heater, etc
  • Light and strong: aluminum coil light weight, but high strength, good wind resistance.
  • Corrosion resistance: Aluminum has good corrosion resistance, and the surface has an anti-corrosion layer, so the color coated aluminum coil is more durable.
  • Easy processing: Aluminum coil and color painted aluminum coil are easy to cut, press and bend, and can be customized according to actual needs
  • Color coated aluminum coil does not contain harmful substances, meets environmental requirements, and the waste can be recycled and reused
Wet storage stain, or white rust, is the term for the white, floury and loose corrosion products shown in below figure. White rust is preferably formed on newly galvanized surfaces.
 
White rust only forms if there is water(rain or condensation) on the galvanized surfaces, If the galvanized steel are stacked tightly, the attack will primarily take place in gaps where ventilation is poor.
 
White rust is created due to a corrosion process, that is increased by the fact that there is relatively more oxygen at the edge of a water film or a drop of water, than in the middle.
 
A so-called “oxygenation element” is formed   because the oxygen-rich areas become nobler cathodes than the oxygen-poor anodes. Such oxidation elements can also cause corrosion on black steel, stainless steel and aluminum.Since this white corrosion product is very bulky(about 500times that of the zinc from which it was formed), it can appear to be serious.
 
Though, the white rust is normally not harmful to other of the coating’s properties, and the standard for hot-dip galvanizing, EN ISO  1461: 2009, states that white rust is not cause for rejection providing the thickness of the zinc coating meets the specified minimum value.
 
 The formation of condensation water, which can occur on the GI GL PPGI PPGL AL PPAL  products due to varying temperatures during outdoor storage under tarpaulin or equivalent,should therefore also be avoided.
 
1.Better to be preserved in a ventilated and completely dry conditions.
 
2.For outdoor storage, the GI GL PPGI PPGL AL PPAL products should be stacked with wood sloops,make sure there is good air ventilation around all surfaces and rainwater can run off all surfaces without accumulation.
 
3.Outdoor storage which covered with tarpaulin should also be stacked with spacers so that condensate, formed due to changing temperature, can be removed by air ventilation. 
 
4.The covering on galvanized products should therefore only act as a roof that protects against rain and snow,must not rest on the galvanized steel and must allow air ventilation.
