Galvalume steel coils are available in various types, each suited for different industrial uses. They are made with proprietary alloys of zinc and aluminum. The following are the common types:
Regular Spangle Galvalume Steel Coils
They display a shiny, spangled view on the outside, and this is because of the zinc-aluminum alloys. Galvalume steel coils have UV and thermal resistance as well as a prolonged lifespan. That is why they are recommended for roofing or siding in various settings.
Mini Spangle Galvalume Steel Coils
They provide less visibility of spangles, which means they give a more matte surface. This characteristic is preferential for some sectors that operate under concern regarding the anti-corrosive features of the material. Mini spangle coils find their use in many places, and they also include construction and appliances.
Maxi Spangle Galvalume Steel Coils
Maxi spangle coils are the same as mini spangle coils, but they come with larger spangles. Sometimes, users would prefer the aesthetic features of maxi spangle galvalume steel coils to make them look more attractive for specific applications.
Non-Spangle Galvalume Steel Coils
Non spangle coils are produced to ensure that there are no decorative spangles on the surface. They give a smooth, even view, which is important for printed or painted surfaces. Non spangle galvalume steel coils are ideal for places where uniformity is more important than functionality.
Customized Galvalume Steel Coils
Specialty coils are offered to clients with personalized needs. Customers can decide on thickness, diameter, coating weights, and mechanical properties depending on their preferred applications. Custom galvalume steel coils find importance in particular ventures where standard products cannot be applicable.
The galvalume steel coils possess many features that give them recommended value in several applications. The features that characterize Galvalume steel coils include the following:
Excellent Corrosion Resistance
One of the outstanding features of galvalume steel is its resistance to corrosion. The composition contains zinc and aluminum, providing superior resistance to harsh weather, moisture, and environmental elements. Because of this resistance, the steel coils are considered for roofing, especially in the most aggressive environments.
Long-Lasting Durability
The preceding coating gives Galvalume steel coils an extended lifespan. They are more tolerant than conventional galvanized steel. Coils last longer and are more cost-effective for end clients looking for low-maintenance solutions in construction or manufacturing.
High-Temperature Resistance
Galvalume steel's reflective properties for heat make it useful in roofing and automotive components. It contributes to energy savings by lowering heat absorption in buildings. In equipment manufacture, this property has the potential to improve energy efficiency.
Strong Adhesion for Coatings
Corrosion-resistant properties of Galvalume steel enable better adhesion for paints, polymers, and organic coatings. This enhances the material's versatility and allows it to be useful in many industries, including construction, where aesthetic and functional coating properties matter.
Aesthetic and Functional Features
Gavalume coils' glossy and metallic appearance make them attractive for end users. In building sectors, the look is welcomed. Also, the spangled galvalume is preferred as it has a shiny form. The steel also has its aethetic properties and adds to the anti-rust coating properties of the material. Therefore, it becomes useful for both practical and visual appeals in a variety of applications.
Galvalume steel coils have a variety of uses in different industries. These uses are determined by the unique properties of the coils. Some of these applications are as follows:
Building and Construction Applications
Heating, ventilating, and air conditioning ducts in buildings are made of Galvalume steel coils. They have properties of corrosion and durability. Popular applications are roofing panels, wall cladding, and other structural components. For galvalume steel roofing, the long lifespan and low maintenance requirements make the coils ideal. Apart from this, the reflective nature of Galvalume aids in energy efficiency. This leads to prolonged energy savings for the end users.
Automotive Industry
Due to their resistance to corrosion, durability, and cost-effectiveness, Galvalume steel coils are widely used in the automotive industry. They have several applications, such as body panels, roofs, and components for undercarriages that are prone to rust. Also, the aluminum-zinc coating minimizes heat absorption, making it easier to maintain and more suitable for its use in regions with hot climatic conditions.
Manufacturing of Appliances
Coils of Galvalume steel are regularly used in manufacturing appliances such as refrigerators, washing machines, and dryers. It is highly lustrous and has great resistance to corrosion. Also, Galvalume offers a long-lasting coating for internal and external components in appliances that are located in humid areas or have high moisture levels.
Roofing Solutions
Because of the superior qualities of long-lasting and corrosion-resistant materials, Galvalume steel coils are preferred for roofing solutions. They are the materials used in coated shingles, standing seam roofs, and corrugated roofing sheets. Some popular features include high reflectivity, which helps reduce heat absorption in the building and enables better protection from the elements.
Solar Panel Frames
Galvalume coils are also used in solar panel frames. Their durability and resistance to corrosion ensure that the frames withstand environmental aggressors, including rain, snow, and extreme temperatures. This makes them appropriate for outdoor use and extends the systems' total longevity.
The following factors should be considered when choosing galvalume steel:
Thickness
The thickness of the steel coil chosen will depend on the intended use. The common thicknesses that can be found are between 0.15 mm and 1.2 mm. The thicker the coil, the stronger and more durable the coil is. However, thicker coils are harder to work with. They are best for roofs on commercial buildings.
Coil Width
Galvalume steel coils come in varying widths. The widths often range from 600 mm to 1250 mm. Note that the required width will be determined by the recipient’s purpose. If the coil is to be used for roofing, custom widths are to be used to reduce the number of joints during installation.
Coating Weight
The coating weight should be chosen according to the level of protection required. The higher the AZ ratio, the better zinc will be used for processing. Generally, AZ30 is enough for internal automotive parts. AZ150 is the most popular because of its balance between cost and durability. AZ300 is thicker and is ideal for harsh outdoor conditions.
Mechanical Properties
Buyers should ensure they check the mechanical properties of the steel coil. The tensile strength should be within the range of 300 to 600 MPa for optimum performance. Also, elongation percentage should be at least 5%. This tests the coil's ability to hold up to bending and shaping without breaking.
Galvalume Steel Coil Prices
Galvalume steel is practical for buyers on a budget since it offers good value from lower material and maintenance costs. Normally, prices depend on the required thickness and coil size. Also, the distance to be shipped affects the final cost. If buyers order large quantities, they will benefit from price discounts.
