Galvalume Steel Coil

The galvalume steel sheet is composed of aluminum-zinc alloy. It is composed of 55% aluminum, 43% zinc and 2% silicon solidified at 600 ℃. And its whole structure is composed of aluminum-iron-zinc to form a kind of dense quaternary crystal alloy. Galvalume steel coil is an important alloy metal that is often used in daily life.

Galvalume steel coil has many excellent features such as strong corrosion resistance which is 3 times than galvanized steel sheet. The surface has beautiful alum-zinc flower, can be used as building outside panel.

The corrosion resistance property of galvalume steel coil is mainly due to the aluminum component and the aluminum’s protection. When the zinc is worn, aluminum forms a dense layer of alumina in order to prevent further corrosion of the corrosive material.

Second is heat resistant property. Galvalume steel coil has good heat resistance. It can bear more than 300 degrees Celsius high temperature which is similar to aluminum steel plate. Galvalume steel sheet is often used in chimney tube, oven, lighting and gluorescent shade.

Galvalume steel sheet has a high thermal reflectivity that is twice that of a galvanized steel sheet and is often used as base material for insulation products.

Because of the 55% density of AL-Zn is smaller than the density of Zn, with the same weight and same zinc layer coating thickness at the same circumstances, the galvalme steel sheet’s square is 3% bigger than galvanized steel sheet.

Our high quality galvalume steel coil is mainly used in construction, automobile, home appliances, agricultural, etc. If you would like our products, welcome contact us.

The Process to produce Color Coated Aluminum Coil

The color coated aluminum coil is made by roll painting on coating line. The process is not as simple as imagined. The color coated aluminum coil is refers to the aluminum coil with face painted effect which also can be called pre-painted aluminum coil, color aluminum coil. The first purpose of coating treatment is to make the construction, decoration, home and other products beautiful. Second effect is the coating process and thickness directly affects the color coated aluminum products quality and durability.

The general production process with roll coating has five steps which is coil input, cleaning and chemical treatment, painting, curing and finished product output. The process layout and equipment composition is different under different situation, but basic parts are the same.

First, the raw material coil input, is the uncoiler continuous rewinding to ensure continuous transmission of the coil with a stable inputting to production line. Some lines choose take the cross-beam—type loader, and some lines choose to use two sets of alternating before and after the set uncoiler. In short, all this two ways is to ensure supply coils in time.

Second, surface cleaning and chemical treatment, is to clean and chemical pretreatment the top and bottom faces of the aluminum coil in order to ensure that the paint can be firmly attached the coil.

The third is painting. Each production line should have at least two roller coating machine to ensure prime and top coats can be two layers coated.

Forth is the paint layer curing that is the roll coil which is finished painted just now should be completed curing before touch the next roller to avoid mutual adhesion and destruction. Generally, it has at least two curing boxes in a production line.

Fifth, refers to finished products output. It should ensure the production line’s speed and finished coil transfer synchronization.

Different manufacturers can provide different production technology. Its high standard of quality pursuit is reflected in the production details. Changzhou Dingang Metal Material Co., Ltd, we set high demand on us from cleaning, to pretreatment, to painting, to drying with harsh process standards. Our color coated aluminum coil can ensure uniform color, high gloss, no strips and stains. The coils can ensure a higher strength and weather ability in harsh environment. We Changzhou Dingang Metal Material Co., Ltd can be your trusted business friends. Welcome your inquiries.

The Production Lead Time for Pre-painted Aluminum Coil

One of the most important points of an order which customers care about is production lead time. A planed and in-time lead time can help to save suppliers and customer’s lead-time and profit.

To us, because there are too many colors, our factory almost has no color coated aluminum stock. If buyers place order, the colors we make according to RAL color chart or as customized. So we always need a certain processing production time to finish the color coated aluminum coil. It is better that customers advise us their expected lead time, consider our processing time, try to arrange the order in advance in order to avoid too late delivery.

The lead time of PVDF coated aluminum coil is normally longer than PE ones which is mainly because PVDF paint is used Nippon brand paint. All of Nippon paint’s deploy is regularization. The color modulation is always after the lab data’s stability. So the lead time for PVDF color coated aluminum coil is normally approx 20days. Surely, if the thickness and specification is normal such as alloy, temper, normal RAL color, we can shorten the lead time to 10-15days.

The lead time for PE coated aluminum coil is some shorter than PVDF because the simple color modulation of PE paint and many big PE paint manufacturers can supply us. So normally it will be need 5-10 days to produce PE coated aluminum coil.

The above is a brief introduction of our PVDF and PE coated aluminum coil. Wish we can cooperate well by mutual understand and trust. Welcome read our website for more understanding. It will be appreciated if we can receipt your inquiry.

The Color for Color coated Aluminum Coil

The color of color coated aluminum coil can be customized. Our factory can provide different kinds of color coated aluminum coils such as PE and PVDF coated coil. Changzhou Dingang Metal Material co., l td can modulate the color as customer’s requirement. We provide customers kinds of colors and paints coated aluminum coil which has the stable, not shed paints for long use years. And the paint thickness is average and no color difference. The property of color coated aluminum coil is very stable, not easy corrosion. The good or bad of color coated aluminum coil molding will affect much the color coated aluminum coil appearance and property. Now I would like to share you some information regarding the coated aluminum coil molding.

1.   To painted aluminum coil, all the base metal plate surface will be remained with some oiled and lubricant. Also, it will be adhesive some material during the shipment. It will be not good for the use of color coated aluminum plate without wiping off the oil and adhesive material.

2.    It should be needed chemical treatment for a stable conversion coating on the cleaned metal surface in order to improve the base metal anti-corrosion and adhesive force for paints. The base metal pretreatment technology lays a basis for making priority paints.

3.   For the color coated aluminum, the coating method is the general color coated aluminum coating process according to the coating layer of paint. It can be divided into three coating process, two coating process and single coating process. According to the coating roller and the direction of rotation of the drive roller can be divided into two kinds of coating, positive and reverse coating process. You can get the required thickness, appearance of the coating.

In addition to the purchase we have to pay attention to its performance, but also carefully check its appearance. To qualified coated aluminum coil, the surface has no obvious indentation, leakage coating, through the coating damage, and ripple problems. These are very easy to check out, and the most important thing is that you have to carefully look at the color of the coated aluminum coil, if you do not pay attention, it is not easy to see, but in the application it will affect the final decorative effect.
