Structure of Prepainted Aluminium Coil:
Coated aluminum coil/sheet are of a wide range of colors, which gives wonderful appearance no matter in residential and commercial constructions of great exhibition centers.
The coated aluminum coil/sheet have been widely used in the fields of construction and decoration( garage doors, ceiling etc.), electronic appliances, lighting decoration, air-condition air pipes, sandwich panels and drainages etc.
Main Features of Prepainted Aluminium Coil:
Low welding costs.
Outstanding color compatibility after anodizing
Easy to operate. All-position welding.
Excellent corrosion resistance.

FAQ of Prepainted Aluminium Coil:
a: Where is your factory?
b:Now which countries do you export your goods?
Now we export to South East Asia,Africa, North America,South America ect.
- Q:what's the difference between the knocking voice of aluminum sheet and stainless steel?
- The voice of aluminum sheet is toneless, and the voice of stanless steel is more crisp.
- Q:what kind of abradant should be used in the deburring of aluminum sheets? How to grind?
- we usually use resin grind stone to grind aluminum sheets, Vibration Grinding Mill is also ok.
- Q:why does 10% sulfuric acid not react with aluminum sheet?
- 10% sulfuric acid has a high concentration and will be passivated and formulate a layer of oxide film after reacting with aluminum,and the reaction will stop after seperating sulfuric acid
and aluminum. there is a layer of Al2O3 oxide film on the surface of aluminum, so it's hard for sulfuric acid to break the oxide film and react with aluminum.
- Q:why can't aluminum sheet burn after polishing?
- because aluminum will rapidly formulate dense oxide film once being exposed in air, oxide film will generate after polishing, it can't burn.
- Q:Could induction heating fuenace be packaged with aluminum foil as insulation material?
- It’s useless. Aluminum foil will generate eddy and emit heat after medium induction, which will reduce the thermal efficiency of medium frequency. Now I provide a method for reference only. Induction coil will be water cooling and is packaged by thermal cement and other materials. Use asbestos sheet and other materials to transform the both ends of induction heating coil as baffle which is mobile and convenient for load and unload. When steel tube is heated in the induction coil, you can put down the baffle to prevent large loss of heat, shorten heat time and improve heat efficiency. When the seamless steel tube is heated into setting temperature, you can open the baffle to conduct expanding process, and you don’t need to think about the thermorytic problem of steel tube in the expanding process. It’s important to shorten the time of expanding process. Baffle is used for heat retaining of medium frequency heating and extrusion forming in our factory. The method above for reference only.
- Q:which kind of material won't influence magnet attracting iron nail? Does copper sheet or aluminum sheet influence it?
- Copper coil will impede magnetic penetration. People separate the magnet from the workpiece of machine tool to avoid magnetic short circuit and attraction loss, making magnetic line of force go through the workpiece. An opening copper bush is added into the iron core of magnetic closing coil or opening solenoid to avoid the iron core being attracted on the external iron piece and stop operation. The opening is for avoiding eddy formulation and short circuit, iron core in copper bush is the ruled magnetic circuit.
- Q:how to distinguish the physical property of copper sheet from the one of aluminum sheet?
- physical property: copper sheet: golden, heavy, aluminum sheet: white, light.
- Q:why intact aluminum sheet stop quicker than pectinate one in the magnetic field?
- while swinging in the magnetic field, intact aluminum sheets will formulate inner eddy current,that is the annular induced current.eddy current will transform the mechanical energy into heat energy, which makes the aluminum sheet stop quickly.but pectinate aluminum sheet can't formulate intact eddy current, so intact aluminum sheet stop quicker than pectinate one.
- Q:what kind of aluminum sheet is suitable for aluminum alloy double-edged saw?
- saw web size depends on the thickness and height of sectional material,equipment compatibility and permitted installed saw web size .
- Q:is general aluminum sheet fire-proof?
