Metals & Alloys Industry - Material

Galvalume steel coils are manufactured from cold-rolled steel (CR steel) or hot-rolled steel (HR steel), coated with an alloy containing 55% aluminum, 43.4% zinc, and 1.6% silicon. The coating is usually applied through a process called hot-dip coating, where the bare steel is dipped into a vat of molten alloy. The resulting coating is highly resistant to rust and corrosion due to the combination of zinc and aluminum.

There are also galvalume steel coils that undergo pre-paint processes. These coils are coated with different types of paints, including epoxy paint. The paint forms a protective layer, providing additional rust/corrosion and UV damage protection. Gavalume steel coatings can also be replaced with or complemented by several other coating types, such as polyester and polyurethane coatings, depending on the specific intended use and the buyer's preferences.

Steel is a premium choice for constructing galvalume steel coils because of its unique combination of strength and flexibility. Galvalume steel offers exceptional durability, making it ideal for building and construction projects. Additionally, the surface of steel is easy to recycle, making it a sustainable choice.

Metals & Alloys Industry - Usage Scenario

Galvalume steel coils are preferred in various construction and building material applications due to their unmatched resistance to weather elements. This makes them ideal for roofing and exterior cladding. In the automotive and transportation sector, galvalume steel parts are coated with chrome surface treatments for aesthetic purposes and protection from corrosion due to exposure to water and other elements. Household appliances such as washing machines, dryers, and refrigerators also contain parts made of galvalume steel due to its affordability, durability, and resistance to corrosion.

Galvalume steel coils are used in manufacturing outdoor furniture such as grills, chairs, tables, and storage units. It is also commonly used for agricultural equipment that will be constantly exposed to harsh weather elements. For industrial applications, galvalume steel is used in silos, storage tanks, and conveyor systems. These coatings serve as a cost-effective alternative to stainless steel in environments where corrosion is a concern. Galvalume steel coils are also used in manufacturing coatings that protect the coated material from UV radiation and other harmful chemicals. Invention of new technologies and rising costs of other materials are expected to drive the demand for galvalume steel coils in the coming years.

Metals & Alloys Industry - Shipping & Picking

The standard packaging for galvalume steel coils is wrapping with plastic film to prevent scratches and corrosion during transportation. Buyers can also request for additional protection such as steel bands, wooden crates, and boxes to increase the coil's integrity and resistance to shipping damages. Galvalume steel's weather resistance allows it to be transported under most weather conditions as long as reasonable precautions against water ingress are undertaken. Regular checks on the coils during transportation are necessary to ensure no significant rust or damage has occurred.

Transportation options also include trucks, trains, and ships, with trucking offering the most flexibility and quicker options for shorter distances. Trains and ships are cost-effective for transporting large quantities of steel over long distances. Buyers can also choose to delay shipping based on market conditions or storage availability. Communication and coordination between buyers and suppliers are crucial in managing shipping timelines and ensuring delivery meets the buyer's requirements.

Metals & Alloys Industry - FAQ

How does galvalume steel compare to galvanized steel in terms of corrosion resistance?

While galvanized steel offers adequate protection against rust by utilizing a zinc coating, galvalume steel offers better protection against rust and corrosion due to the addition of aluminum to the coating alloy. The improved resistance is particularly durable in harsh and corrosive environments. Gavalume steel also maintains its resistance longer than galvanized steel when both are exposed to rough elements outdoors.

What industries benefit most from using galvalume steel?

The building and construction, automotive, home appliances, outdoor furniture, agriculture, and industrial storage and transportation sectors typically benefit from the distinct properties offered by galvalume steel like corrosion resistance. Galvalume steel is also a better value alternative to stainless steel in various applications.

Are there environmental concerns associated with the production of galvalume steel?

There are some mild environmental concerns associated with the production of galvalume steel due to the emissions and waste generated during steel production and coating processes. Nevertheless, its durability and resistance to corrosion make it likely to have a lower environmental impact over its lifespan because it requires less frequent replacement, helping to reduce waste and resource consumption in the long run.

How does the performance of galvalume steel in coastal areas compare to other materials?

Due to its superior resistance to rust and corrosion, which is often caused by salty air and water in coastal environments, galvalume steel performs better than galvanized and zinc-coated steel. The 55% aluminum coating provides unmatched protection against corrosion for at least 10 years compared to other coatings.

Can galvalume steel be recycled?

Yes, Galvalume steel is highly recyclable. In fact, it is one of the most recycled materials in the world. Its recyclability helps it to be more environmentally sustainable, reducing waste and resource consumption at the end of its life.
