Product Description:

1.Structure of Product Description

PE Coated aluminium coils are widly used in decoration field.Now we mainly exported to Asian countries and European countries.For the paint, it depends on the using evironment.  If you use in the open air, we recommend the PVDF coated aluminium coils. This kind of painting can last 15-20 years.  If you use in the room, we recommend PE coated aluminium coils. The price is much more competitive.


2. Main features of the product

a.Competitive price---We have our own mills and can produce mill finished aluminium coils, so we can control the production cost better.


b.Professional after-sale service---We have more than 15 years exportation experience and you need not worry about the exporation problems.


c.Fast delivery time---We can control the delivery time within 35 days.

Q:Why do the layers loose when taking out coil after roll of aluminum 0.14?
After rolling, the most possible reason may be poor deoiling effect. I think, for 0.14mm aluminum coil, the lining sleeve will not be forgotten. After rolling , oil ooze from aluminum layers, and the support of aluminum coil is not enough, leading to coil collapsing. The specific manifestations are that the edges of even round aluminum layers become like water ripple, and that the aluminum coils suddenly become uneven when taking out coil.
Q:How much cube is the 0.9mm aluminum rolling?
This is a common problem. Anyone who had received high school education can calculate it very quickily. One way is to calculate sectional area with circular area, then times the thickness of the aluminum rolling. Another way is to use the outer diameter circular area to subtract the core area and then times the thickness of aluminum rolling.
Q:How to calculate the weight of strips with the weight of aluminum coil known?
Thickness*width*length=weight/density, length=weight/(density*thickness*width).Ps: Keep unit the same.
Q:Why 5052 turn black after annealing during the production of aluminum alloy?
The aluminum oxide in the surface has been oxidized by other chemical elements.
Q:How to calculate the wall thickness with the gross weight of aluminum coil known?
Gross weight*density=volume volume÷(aluminum sheet *width)=thickness
Q:How much is the rust-proof and thermal insulation aluminum coil?
3003 alumal alloy is the best and common rust-proof and thermal insulation aluminum coil. The price depends on the thickness and width you need.
Q:The specification of thermal insulating aluminum coil
4-0 In general, the chemical engineering products for thermal insulation is 0. According to the International standard, the thickness tolerance is +-5%.02MM. according to industrial standard, it is +-0. The production crafts are embossed and plain sheet.
Q:How to measure the thickness of aluminum coil at real time? In what areas can the sensor be used?
I suggest that you use the laser displacement sensor for real-time measurement of the thickness of aluminum coil. ZLDS100 can exactly measure the change value of aluminum coil thickness through simple technique in the thickness measurement project, which can help judge the production phase and status.
Q:Can aluminum coil 3003H24 replace 3A21H14?
It is ok in some way as both of them are alumal. The hardness of 3003H24 is similar to that of 3A21H14 after hardening without annealing. Both have good corrosion resistance, plasticity and bad machinability. They cannot be used as load bearing parts even though small load is ok. They cannot be anodized.
Q:How to use aluminum sheet to roll a 12m-long aluminum coil with a diameter of 184cm?
According to project experience, first you should check the specification of the aluminum sheet and then design crafts such as connection method, installation and transportation according to equipment.
