Popular Material for Making Roofing

In my spare time, I would like to watch some TV shows to enjoy life. But as a qualified export sale, we need to find useful news when enjoying the shows. Please look at below photo which comes from a big parent-kind reality show of China Daddy where Are We Going. The man in this photo is not the key point I would like to talk today even though he is the popular handsome host of this show called CUNZHANG.

Do you see the background which catches my eyes when I enjoyed the show? Yes that what I am interested in--Roofing. I wouldn’t like to guess it is Pre-painted steel roofing or Color coated aluminum roofing. If it is you, what material you would like to use for serious environment?


If it is me, of cause I will prefer higher quality color coated aluminum roofing. Why? Because of the longer warranty and durability; second the light weight and easy molding. Of cause there is another reason- recycling. There are too many advantages of aluminum material than steel. But then an important question will come for considering. What are the most suitable specifications of color coated aluminum roofing for serious long time wind, snow environment? No worry, below I suggest you some:

Main alloy: A3004, A5054, A5754
Typical width: 580mm, 600mm, 1000mm, etc

Supply-side reforms have helped strengthen the industry further this year


Aluminum Corp of China, the country's largest nonferrous metals company, announced its best half-year performance in nine years, riding a surge in commodity prices.

Also known as Chinalco, the company said in its interim report for 2017, which was released late on Thursday, that first-half revenue reached 91.31 billion yuan ($13.68 billion), up 83 percent year-on-year, which yielded a profit of 751 million yuan, up 1,006 percent year-on-year.

A surge in sales volume as well as prices, particularly of its main products, boosted the first-half revenue and profit, Chinalco said.

Aluminum prices have been on a rebound since last year, and continued to be strong in the first half of this year.


For instance, the average aluminum price on the Shanghai Futures Exchange was 16670 yuan per metric ton in the first half, up almost 45 percent year-on-year.

"Since April last year, the aluminum sector has been making profits," said Li Lin, an analyst at Sublime China Information Group in Zibo, Shandong province, adding that the average profit reached last year's highest level of 2,000 yuan per ton in October.

In April, regulators such as the National Development and Reform Commission, the country's top economic planner, announced that illegal projects, which increased overall industry capacity since May 2013, would be asked to close down.

Within six months, the electrolytic aluminum sector saw such projects eliminated, which kicked off the capacity cutbacks.


Shandong, the largest aluminum producing province in China, said on July 24 it would close projects that used to produce 3.21 million tons of the metal, following similar measures by several other provinces.

In 2014, Chinalco reported a deficit of 16.2 billion yuan, losing the most among the listed companies in A-share market.
However, in 2015, the company began to make profits. It made 206 million yuan in 2015. In the fourth quarter of last year alone, Chinalco realized an operating profit for the first time in five years.

The latest interim report confirms that Chinalco has made a profit in three consecutive quarters.

The Seventh Round Strict Air Pollution Inspection Completed

The seventh round of the yearlong strict inspection on air pollution had been completed by Jul.20th.Between Jul.7 and Jul.20,the inspection teams checked a total 5,322 business (organizations),and found environmental incompliances in 1,389 of them.Of the incompliant enterprises,347 were unlicensed small polluters,two did not attain emission standards,252 failed to install pollution control facilities,160 failed to keep such facilities in normal operations,536 had VOCs control problems,and four had other problems.

The inspection results showed VOCs control was the primary pollution problem,which accounted for 38.6 percent of the total problems revealed by this round of inspection.Tangshan Municapality is the home to 54 VOCs emitters,the largest number in the 28 target cities.From the industrial perspective,the rubber and plastics manufacturing,machinery manufacturing,coating and spraying,plywood,packaging and printing industries contributed the largest share of VOCs emission.

There were 347 unlicensed small polluters which violated the environmental legislations,accounting for 25.0 percent of the total incompliant enterprises.The fugitive emission was serious.

Starting Jul.21,the inspection team launched the eighth round strict inspection over the air pollution in the Beijing-Tianjin-Hebei region and surrounding areas.

On the sidelines of the eighth strict inspection,the ministry is about to initiate six rounds thematic inspection in Hebei and Henan on their performance in the implementation of the detailed plans for implementing the action plan against air pollution.The thematic inspection,which will last for 84 days,the targets at tight cities in Hebei and seven cities in Henan,with each city under the scrutiny of an inspection team.

The Ministry required that the inspection teams touring Hebei and Henan provinces strengthen the inspection and urge the local governments and relevant departments at all levels to take the responsibilities for air pollution control and make sure the tasks specified in the local plans for fighting air pollution to be completed before deadlines.


The production of checkered aluminum sheet

We can see many styles of checkered aluminum sheet on the building material market. But can you imagine how it is produced out? Do you know the producing process? Hereby we share with you some knowledge and hope you will find some useful information.

We can see the five producing steps for checkered aluminum sheet as following.


1.      Ingredients
To calculate the components of different alloys on the basis of exact needed alloy. Then we can match with a reasonable amount of raw material.

2.      Melting
Putting the ready raw material into the furnace according to the production requirements for melting, and then we can dispose of the slag and gas in the material by using degassing and shimming method.

3.      Casting
Under the condition of proper casting, we can cast the cooled aluminum liquid in the deep well cast system into various sizes of round casting rods.

4.      The extrusion of checkered aluminum sheet
It needs to extrude the heated round casting rods in mold. The wind cold hardening and heat treatment process and the artificial aging process should be applied to use for completing the heat treatment. Different types of round casting rods will use different heat treatment strength.

5.      Paint
Painting is the last step. Before painting, we need to oxide the aluminum checkered sheet in order to achieve the desired results.

If you need exact length of sheet, there can add a final step is cutting.

Above all is the producing process of checkered aluminum sheet. I think you will get some acknowledge of it. Besides of the checkered aluminum, we also hot manufacture the color coated aluminum, mirror aluminum such kinds of high quality coils and sheets. If you have interests on our product, welcome to our website.

Advantages of Colored Aluminum Coil in Outdoor Environment

It can be said that the invention of paint has a milestone meaning in the metal material anti-corrosion subject. In the daily life, paint is closely related to us such as cars, mobile phone shells all are painted surface. Paints not only play a decorative effect, but also play a very important anti-corrosion property. Colored aluminum coil is coating a variety of paint on the plain aluminum surface, and then improve the anti-rust, anti- corrosion properties of aluminum products. Also it can play a good decorative effect.


Aluminum alloy has the natural anti-rust and corrosion resistance effect in the outdoor environment, but it will lead to color shading problem because of aluminum alloy surface oxidation. However, the appearance of colored aluminum has just solved the problem of aluminum surface and further increase the life of aluminum coils and sheets. Using colored aluminum coil in the outdoor environment can increase the using life largely extend and beautify the product.


One of the advantages of color coated aluminum is the surface color won’t be changed, and it can keep bright and clean as a new by long time use. As we all know the Pre-painted steel coils will be soon rusted and corrosive after surface paint broken. Nevertheless, the color coated aluminum coil is not like pre-painted steel coil. Even if the paint surface is not good looking, there will be no corrosion and rust problem, which is one of the advantages of color coated aluminum coil.

The second advantage I would like to talk is the light density. Compared to steel, the density of aluminum is light, so it is often used in aerospace. In construction area the color coated steel tiles will be soon replaced by color coated aluminum, not only because the good anti-rust property, but also the light weight to small press for the steel structure.

For above advantages of coated aluminum coil using in the outdoor, we Changzhou Dingang Metal Material Co., Ltd mainly produces below specifications of color coated aluminum coils and sheets.
