Galvalume/Aluzinc Roofing Sheet (GL)
Galvalume steel sheet is an important alloy material often used in daily life. The Galvalume steel plate is composed of an Al Zn alloy structure, which consists of 55% Al, 43% Zn, and 2% Si solidified at 600 ℃. The whole structure is composed of Al Fe Si Zn, forming a dense quaternary crystal.

Difference Between The Galvanized Sheet And Aluminized Zinc Sheet:
The difference between galvanized sheets and aluminized zinc sheets mainly lies in the difference in the coating. A layer of zinc material is evenly distributed on the surface of galvanized sheet, which plays the role of anode protection for the base metal. In other words, the alternative corrosion of zinc material protects the use of base metal. Only when the zinc is completely corroded can the base metal be damaged.
The surface coating of aluminized zinc plate is composed of 55% aluminum, 43.5% zinc, and a small number of other elements. The surface of aluminized zinc coating is a honeycomb structure in microcosmic, and the "honeycomb" composed of aluminum contains zinc. In this case, although the aluminized zinc coating also plays the role of anode protection, on the one hand, due to the reduction of zinc content, on the other hand, because the zinc material is wrapped by aluminum, it is not easy to electrolysis The function of this anode protection is greatly reduced, so once the aluminized zinc plate is cut, it will rust quickly when the cut edge is basically lost. Therefore, the aluminized zinc plate should be cut as little as possible. Once the edge is protected by antirust paint or zinc-rich paint after cutting, the service life of the plate can be extended [1].
Advantages of Galvalume/Aluzinc Roofing Sheet (GL)
Aluminum zinc alloy steel plate has a good heat resistance and can withstand the high temperature of more than 300 degrees of food intake. Its high-temperature oxidation resistance is very similar to that of aluminum plated steel plate. It is often used in chimneys, ovens, illuminators, and lampshades.
The corrosion resistance of the galvaume corrugated metal is mainly due to the protection function of aluminum. When zinc is worn, aluminum forms a dense layer of alumina, which prevents corrosion-resistant materials from further corroding the interior.
The thermal reflectance of the Al Zn coated steel sheet is twice as high as that of galvanized steel coil. It is often used as thermal insulation material.
Because the density of 55% Al Zn is smaller than that of Zn, the area of the Al Zn plated steel plate is more than 3% larger than that of Zn plated steel plate under the same weight and the same thickness of gold plating layer.

Here is my Vietnamese wife status. As a Singaporean born and raised, I am a true blue citizen.
First LTVP application: 1 year LTVP
First LTVP renewal: 3 years LTVP plus
The first application was rejected after 7 months, the appeal was rejected after 3 months during trimester of pregnancy, and the current application is still pending after 10 months. The journey of a PR application is unknown. My baby is now 10 months old.
❱❱
As an update, my wife's PR is still pending after 11 months, this month marks the one-year anniversary. I just celebrated my child's first birthday. I am starting a new job in November 2023. Do I need to notify ICA of that? There is a 1k difference between the new salary and the amount reported to ICA a year ago. As a result of low increments this year, my salary did not increase much over the last few months. The month of July is when I receive my salary increment.

Actually, among other things, there are plenty of Chinese schools in Malaysia where the medium of instruction is Mandarin. My wife is from one such school. As are many Malaysian Chinese you see in Singapore. This includes many who are doing well in the corporate world.
As far as India is concerned, I think you are perhaps forgetting that there is a large number of Indians who either don't have access to school or they are studying in non English medium schools. For us middle class Indians, it's easy to be blinded by the sight of the more privileged Indians (which includes us). Also, there is a billion and a half of us which is nearly 18 percent of the world's population. Of course, we are going to be prominent on the world stage, as are Chinese who are another 18 percent of the world.

Yes, I am talking about middle class Indians. I am 44 years old now and was born in 1980 when India was horribly poor country .....

This is a bit off topic, but I just came to know that in Malaysia, their entire education is in Malay language. My Malaysian chinese colleague who has now turned into a Singaporean told me, she did her primary education in Chinese language and then secondary in Malay language. She speaks English pretty well just like other Singaporeans. She must be really talented and skilled to have done well inspite of the language barrier.
Now I realize why so many Malaysians live in JB and send their kids to Singapore for education for the English language. The poor kids wake up at 4Am,really pity them
I just realize how fortunate we Indians are because our entire education is in the English medium. We do have 2nd language Hindi etc. But main subjects instruction is in English medium.
I realize now why Indians do so well globally and why there are hardly any Malaysians or Indonesians who are famous at the global .....

Irrelevant or maybe it is.

However, Shanmugam shared that the percentages are not maintained to keep the Chinese community percentage at 70 per cent, but the main community concerned about immigration is the non-Chinese community.
He shared that when he has dialogues with senior Malay community leaders, the main question he gets is whether the government would set the community percentage to 14 to 15 per cent.❱❱
