Why do many people choose galvalume steel sheet now?

Galvalume steel has a silvery white ornate finish.

 

Heat reflective

The thermal reflectivity of galvalume steel sheet is very high, twice that of galvanized steel sheet, and it is often used as a thermal insulation material.

 

Heat resistance

Galvalume steel sheet plate has good heat resistance and can withstand high temperatures of more than 300 degrees Celsius.

 

Corrosion resistance

The corrosion resistance of galvalume steel coil is mainly because of aluminum, the protective function of aluminum. When the zinc is worn away, the aluminum forms a dense layer of aluminum oxide, preventing corrosion-resistant substances from further corroding the interior.

 

Lasting

Galvalume steel sheet has excellent corrosion and wear resistance. Its corrosion rate is about 1 micron per year. Depending on the environment, it can be used for an average of 70 to 100 years, which shows that it is permanent with the life of the building.

 

Easy to paint

The galvalume sheet has excellent adhesion to the paint and can be painted without pretreatment and weathering. Because the density of 55%AL-Zn is lower than that of Zn, the area of the galvalume steel sheet is more than 3% larger than that of the galvalume steel sheet under the same weight and the same thickness of the gold-plated layer.

 

Excellent color and texture

Natural light gray galvalume zinc has a special luster, which is completely different from the color of artificial paint, showing an excellent natural texture. Moreover, the beauty of the building can be maintained from the completion of the renovation to the use of several years. In addition, galvalume steel sheets are naturally compatible with other building exterior wall materials such as marble, masonry, glass facades, etc.

 

Conducive to environmental protection

The galvalume steel sheet can be 100% smel and recycled again, and will not decompose and discharge harmful substances, so it will not pollute the environment, while other metals that come into contact with pollutants will be eroded or corroded, leak metal ions, and enter groundwater, causing environmental problems.

 

Easy to maintain and manage

Galvalume steel sheet not only has a long life, but also has low maintenance costs. Zinc sheet has no surface coating, the coating peels off over time and does not need to be repaired. In fact, both aluminum and zinc can continuously form passivation protective layers in-situ in air with self-healing functions for surface defects and scratches.
