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:why does the bubble apear a few minutes later after putting aluminum sheet into diluted hydrochloric acid?
- Aluminum element is extremely activated and will react with oxygen, generating aluminum oxide, once being exposed in air, so there is a layer of aluminum oxide on the surface of daily aluminum products including aluminum sheet. When aluminum sheet is put into diluted hydrochloric acid, aluminum oxide on the surface will firstly react with hydrochloric acid, generating aluminium chloride and water, the process won’t generate bubble, but after finishing the reaction of aluminum oxide on the surface, when the exposed aluminum element reacts with hydrochloric acid, generating aluminium chloride and oxygen, the bubble appears.
- Q:which kind of aluminum sheet could be bended after being etched?
- general etching materials include stainless steel and copper.
- Q:Which kind of glue can bond two pieces of aluminum sheets?
- oxygen welding
- Q:Which kind of solution should I use while welding aluminum sheet and copper pipe by tin soldering?
- 1, you must use over 350W soldering iron, 2,prepare some borax and tin soldering paster, you can’t use rosin to weld it, 3, polish the pipe to clean with fine abrasive paper and borax, 4, put the pipe and sheet into borax, use the soldering trip to rub on the weldment with some borax. 5, after the pipe and sheet become hot, use the soldering iron with the paster and tin to rub the pipe and sheet in borax, then it can be welded. 6, they can be welded together after welding.
- Q:why does the hardness of 2024 aluminum sheet not increase but decrease after thermal treatment?
- The hardness of 2024 aluminum sheet will decrease after thermal treatment(solution treatment), and it will increase after aging treatment.
- Q:Which kind of glue is best for bonding wood and aluminum sheet together？
- You can use 502 adhesive.
- Q:whst should I notice while welding aluminum sheet and aluminum block?
- two types of aluminum reach melting points, aluminum block must be preheated when you weld them with small current, you will know how to do it. You can use argon-arc welding back and forth, preheat it with small current.
- Q:When water continually sprays on the aluminum sheet, how to avoid corrosion of aluminum sheet and keep its water resistance?
- Don’t worry about it, after aluminum contacts water or air, a layer of oxide film will generate on its surface to separate aluminum from the water or air and protect it, so it won’t be erosive.
- Q:As for cast aluminum sheet or wrought one, which one has faster heat conduction?
- 1,duralumin: it's the alloy of aluminum, copper, magnesium, manganese and other metals. it's suitable for compacting by rolling, and it has a higher strength and hardness than common aluminum products. 2, aluminum: it contains many inpurities, is crisp and easy to be smashed.cast aluminum usually is secondary aluminum, and it is produced by remelting the collected old aluminum pots and spoons.3, wrought aluminum: it contains 98% aluminum and 2% or more inpurities, and is comparatively pure aluminum. its soft priority makes it suitable for being pressed into various shapes, aluminum pots,aluminum lunch box,aluminum sheets,aluminum wires,aluminum pipes are all made by wrought aluminum.you will know their defferences from their definition.
- 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.
