Benefits and Features of Galvalume Steel Coil

Galvalume is a form of coating made up of aluminum, silicon, and zinc that performs the role of protecting metals from oxidation. These coatings are composed of 43.4% zinc, 1.6% silicon, and 55% aluminum. The coating is sprayed across the surface of cold-rolled plates, providing an effective protective layer on substrates.

Galvalume Steel Coil: Features

- Strong potential to deal with corrosion

- High heat reflectivity

- Resistance to extreme-temperature oxidation

- Appealing appearance

- More usable area

- Very easy to process

Technical Requirements

- Heat Resistance

Galvalume steel has impressive heat resistance that could withstand temperatures that exceed 300 degrees.

- Corrosion Resistance

The corrosion resistance of galvalume products is primarily attributed to the protective functions of aluminum. If the zinc actually starts to degrade, the aluminum will form a thick alumina layer which prevents further corrosion in the materials inside.

- Heat Reflective

Galvalume steel is often used as a type of insulating material which has high-thermal reflectance (double those of galvanized steel).

Galvalume Steel Coil Applications

- Construction Industry

The construction industry mainly uses anti-corrosion materials in civil and industrial buildings. Galvalume steel is frequently used in the development procedure of roof grills, roof panels, and more.

- Automotive Industry

In the automotive industry, galvalume steel products including coils and sheets are employed to produce corrosion-resistant equipment and parts for vehicles, cars, and a lot more.

- Light Industry

Galvalume steel merchandise is also utilized to manufacture casings for appliances for the home, kitchen utensils, residential chimneys, etc.

- Agriculture

Galvalume is used in equipment mainly used when it comes to food transportation and storage or processing tools often utilized for fish and meat products.

- Household Appliances

Galvalume steel coils may also be utilized in residential equipment like ac units, electric fans, washing and dryer machines, switch cabinets, refrigerators, microwaves, floor cleaners, copier machines, and more.

- Transportation Sector

Galvalume steel coils and sheets can also be used frequently in car panels, highway walls, car shells, car ceilings, tractors, shipping containers, and lots of other kinds of commercial vehicles.

- Other Uses

As base metal of pre painted galvalume sheet including garbage bins, clocks, billboards, musical instrument casings, photographic equipment, and a lot more.

How Does Corrosion Happen In Galvalume And Galvanized Steel

Corrosion means the conclusion of almost any metal roofing. Galvanized and Galvalume steel roofs are differently afflicted with corrosion.

Galvalume Steel

Aluminum is highly resistant to corrosion so the products often corrode a good deal slower in comparison with galvanized steel.

Galvanized Steel

Galvanizing steel will develop a strong chemical bond which is proof against nicks, scratches, and corrosion. Galvanized steel will likely "self-heal" when it comes to small scratches that occur along the cut-edges. Over time, the galvanized layer within the steel panels will quickly degrade and this is where corrosion will start to spread.

Since the corrosion spreads the steel within the bonded, galvanized layer will begin to shed. The corrosion may be slow, but concurrently steady.

Galvalume and galvanized steel products both provide excellent value across their lifespan. Unlike many other roofing materials like asphalt, for instance, ongoing maintenance is not required to take pleasure from long-term longevity, durability, and appearance.
