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:which kind of abraser should be used for deburring of aluminum sheet?
- as for the polishing of aluminum material, we usually nylon wheel and similar products.
- Q:can the oxide film on the surface of aluminum sheet prevent the erosion of acid liquid? Why?
- yes, acid can react with aluminum oxide , generating salt and water, but its anti-corrosion will be stronger if oxide film on the surface is enough dense.
- Q:which kind of aluminum sheet could be bended after being etched?
- general etching materials include stainless steel and copper.
- 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: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:When water continually sprays on the aluminum sheet, how to avoid corrosion of aluminum sheet and keep its water resistance?
- aluminum will react with oxygen, generating dense Al2O3 oxide film on the surface, once the pure aluminum is exposed in air, it will react with air, generating oxide film to protect it.
- Q:why could aluminum pot be repaired by knocking the aluminum sheet into the pot but not being bonded by glue?
- the oxidation rate of aluminum's surface is very quick, so we cann't use the method of tin welding, and the cost of argon arc welding is very high,so aluminum pot's repair usually uses riveting.
aluminum has low hardness and good ductility, so it can be repaired
by tightly knocking, without the bonding of glue.
general glue will decomposed in open fire, if we bond pot by glue, the pot after repair won't be able to endure high temperature.
- Q:What are the colors of iron sheet and aluminum sheet?
- silver white
- Q:How could two pieces of aluminium flakes be welded together?
- You can use argon arc welding, connect the positive pole with alternating current,aluminum wire as the welding wire.
- Q:how to connect copper pipe and aluminum sheet?
