Generally, galvalume steel is an Al-Zn alloy, which uses cold-rolled steel sheets as substrates and then solidifies 55% aluminium, 43.4% zinc, and 1.6% silicone at a high temperature of 600 ° C. This unique “aluminum-iron-silicon-zinc” structure combines the physical protection and high durability of aluminum with the electrochemical protection property of zinc. Therefore, GL steel is more resistant and outlasts [https://wzppgi.com/galvanized-sheet-for-sale/ galvanized steel sheet]. That’s why it’s become one of the most popular materials in today’s steel market. 
- Roles of various composition materials that play you have to know: 
1. Aluminium: can offer strong thermal resistance, long service life, and heat resistance. 
2. Zinc: can offer anti-corrosion ability. 
3. Silicon: can offer heat resistance.

Advantages of Galvalume Steel

1. Strong Corrosion Resistance 
The GL steel is more resistant than GI steel due to the double protection of zinc and aluminum. That is, when the zinc is worn away, the aluminum will form a dense layer of aluminum oxide, preventing corrosive substances from further corroding the steel interior. This also means it has a “self-healing” ability. 
2. Attractive Appearance 
Galvalume often has a gorgeous finish with silvery-white color and smooth surface. And there are many delicate “zinc flowers” that are highly appreciated when used as a building material. 
3. Heat Resistance 
This aluminium alloy steel has a good heat resistance and can withstand high temperatures of more than 300 °C. On the other hand, its thermal reflectivity is also very high, twice that of galvanized steel, thus it is often used as a thermal insulation material. 
4. Great Paintability 
Due to the good adhesion between [https://wzppgi.com/galvalume-steel/ galvalume steel] coating and paintings, it can be painted directly without any pretreatment and weathering. Besides, like hot-dipped galvanized steel, it has good workability and weldability, which can be processed cold bending, stamping, etc., without doing damage to steel surface. 
5. Long Service Life 
Tests conducted under the same outdoor conditions show that the service life of galvalume steel is more than two times that of galvanized steel.

How Long Can This Material Last?

Research conducted by the Metal Construction Association (MCA) indicates that galvalume steel can be expected to provide at least twice the service life of traditional zinc-coated steel under the same exposure conditions. It means galvalume steel could last 50 ~ 60+ years before the corrosion begins to show.

Where Can You Get It?

When buying galvalume steel sheets or coils, Wanzhi Steel can always be your first choice on your shortlist. Wanzhi Steel is an ISO 9001:2015-certified and China-based company, having a factory of 6,000 square meters in Shandong Province. They aim to offer a variety of steel products and value-added services to meet customer needs. They strive to develop long-lasting relationships by providing the right product on time and at a competitive price.
