Galvalume the type of coating composed of aluminum, silicon, and zinc that performs the role of protecting metals from oxidation. These coatings are comprised of 43.4% zinc, 1.6% silicon, and 55% aluminum. The coating is coated on the surface of cold-rolled plates, providing an efficient protective layer on substrates.

Galvalume Steel Coil: Features

- Strong effectiveness against corrosion

- High heat reflectivity

- Resistance to extreme-temperature oxidation

- Appealing appearance

- More usable area

- Simple to process

Galvalume Steel Coil: Technical Requirements

- Heat Resistance

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

- Corrosion Resistance

The corrosion resistance of galvalume products is mainly caused by the protective functions of aluminum. If the zinc starts to wear out, the aluminum will form a thick alumina layer which prevents further corrosion of your materials inside.

- Heat Reflective

Galvalume steel is frequently used as a variety of insulating material containing high-thermal reflectance (double that of galvanized steel).

Galvalume Steel Coil Applications

- Construction Industry

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

- Automotive Industry

Inside the automotive industry, galvalume steel products such as coils and sheets are used to produce corrosion-resistant equipment and parts for vehicles, cars, and more.

- Light Industry

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

- Agriculture

Galvalume can be used in equipment mainly used just for food transportation and storage or processing tools often employed for fish and meat products.

- Household Appliances

Galvalume steel coils are also used in residential equipment for example air conditioners, electric fans, washing and dryer machines, switch cabinets, refrigerators, microwaves, vacuums, copier machines, plus more.

- Transportation Sector

Galvalume steel coils and sheets are also used frequently in car panels, highway walls, car shells, car ceilings, tractors, shipping containers, and several other sorts of commercial vehicles.

- Other Uses

Color-coated steel plates including garbage bins, clocks, billboards, musical instrument casings, photographic equipment, and a lot more.

Galvalume vs Galvanized Steel Coils

Galvanized steel is divided into two categories in accordance with what kind of processing method was adopted.

#1 Hot-Dip Galvanized Steel Coils

Hot-dip galvanizing is actually a method that involves immersing iron sheets within a bath containing molten zinc at around 500 degrees. This method develops a zinc layer over the coils. This process is easily the most common while offering a few stand out benefits:

- The steel surface is entirely covered with the zin layer, which reaches all of the hollows and corners, providing a fully protected surface.

- Hot-dip galvanizing is actually a relatively cost-effective process.

#2 Electro-Galvanized Steel Coils

Electro-galvanizing involves an approach that applies a zinc layer on the steel through a process called electroplating. This process contains a steel conductor plus a saline anode. The goal of this method is to enhance and enhance the heat and corrosion resistance from the steel. Additionally, it produces eye appealing steel sheets or coils.
