Galvalume Metal

Galvalume is a silver alloy coating metal with a smooth surface and beautiful sequins. The galvalume alloy structure is composed of 55% aluminum, 43.4% zinc and 1.6% silicon, and is cured at a high temperature of 600°C. Due to this special coating structure, it has the advantages of excellent corrosion resistance, good process performance, heat resistance, and long life. Its process is the same as galvanized steel and aluminum steel, using a continuous hot dip process. The corrosion resistance of the 55% aluminum-zinc alloy coating of galvlume steel is better than that of galvanized steel of the same thickness. Wanzhi Steel stocks a large number of commonly used specifications of GL metal, with a variety of substrates and coatings to choose from, and accepts customization.

Benefits Of Galvalume Metal

1. Thermal reflectivity: Galvalume metal had high thermal reflectivity, twice that of galvanized steel. You can use it as a thermal insulation material

2. Heat resistance: Because of its good heat resistance, galvalume metal can withstand a high temperature of more than 300℃. It is often used in chimney tubes, ovens, illuminators, and daylight lampshades.

3. Corrosion resistance: Due to aluminum having a protective function, galvalume metal has high corrosion resistance. If the zinc is worn, the aluminum will prevent the corrosion resistance from further eroding the interior.

4. Easy to paint: Galvalume metal and paint have excellent adhesion, do not need pretreatment, and weathering treatment can be painted.

5. Corrosion resistance: The comprehensive anti-corrosion capacity of 55% galvalume metal is 4 times that of galvanized steel.

Uses

Galvalume metal has the advantages of corrosion resistance, hot resistance, cost-effectiveness, thermal reflectivity, etc. Therefore, galvalume metal is widely used in commercial buildings, automobiles, household appliances, and agriculture. In addition, many clients order galvalume metal to produce color-coated steel. The specific applications of galvalume steel are as follows.

• Buildings: roofs, walls, garages, sound walls, pipes and composite houses, etc.
• Automobiles: mufflers, exhaust pipes, wiper accessories, fuel tanks, truck boxes.
• Household appliances: refrigerator backboard, gas stove, air conditioner, electronic microwave oven.
• Agricultural use: Pig house, chicken house, granary, greenhouse pipe, etc.

Galvalume vs. Galvanized: Which Is Better?

1. Composition: Galvanized is coated with a layer of zinc on the surface of steel to form a zinc layer. Based on galvanizing, aluminum is added to zinc to form a zinc-aluminum alloy layer. 2. Performance: The corrosion resistance of galvanized steel is not as good as that of galvalume metal, and its corrosion resistance is not high. Galvalume metal has stronger corrosion resistance and better resistance to acids and salts in the environment.

3. Application: Galvanized steel is widely used in construction, furniture, automobiles, household appliances, and other fields. Galvalume steel is suitable for applications requiring higher corrosion resistance, such as chemical, Marine, and coastal areas.

4. Price: The production cost of galvalume metal is usually higher than that of galvanized steel. That is because its production process requires higher temperatures and more stringent production requirements.

5. Appearance: The surface of galvalume steel is more beautiful than that of galvanized steel, but it may also be more prone to corrosion problems at the cutting edge.

Above all, choose galvalume steel or galvanized steel based on the application needs and environment. If you have questions, we have professional engineers to help you. Welcome to don’t hesitate to contact us!
