What are aluminum sheets?
Aluminum sheets, also known as aluminum plates, are made by crushing and rolling basic aluminum raw materials under immense pressure.
Aluminum sheets are typically manufactured into extremely lightweight yet strong and durable products, making them highly adaptable and easy to install and maintain. In addition, they possess many other unique and excellent properties, making them widely used in numerous fields today, including industry, agriculture, residential construction, and manufacturing.
Three Types of Aluminum Sheets
There are many types of aluminum sheets available on the market today. This section will introduce some common aluminum sheet products from different sources and manufacturers.
Perforated Aluminum Sheets
Perforated aluminum sheets are used when aesthetics are a primary consideration, such as in the construction of various types of flooring, ceilings, screens, sunshades, and other architectural or decorative panels. This is especially common in interior/exterior design work. They are widely used in industrial cleaning and drying stations for rinsing, draining, and collecting functions. Other typical applications include the food industry, factories, or laboratory environments.
Chequered aluminium sheets
Chequered aluminium sheets are metal sheets with a raised pattern on one side and a smooth surface on the other. The height of the raised pattern is typically about 1.5 mm. They are known by various names, including "patterned plate," "anti-slip plate," "five-bar plate," and "Durbar floor plate." They are usually made of aluminum, but steel versions are also available.
These plates are moderately thick and durable, offering better impact resistance and load-bearing capacity, making them suitable for indoor and outdoor areas with high foot traffic and heavy vehicle traffic, such as service corridors, loading docks, and parking lots. The embossed pattern can conceal surface imperfections and increase friction, preventing slipping and skidding.
Aluminum Composite Panels
Aluminum composite panels, or aluminum plastic panels, consist of two thin layers of coil-coated aluminum strips. Their abbreviations are ACS or ACP (usually plastic). They are often used as thin, strong panels for building facades or exterior cladding and are also widely used in various insulation and folding panel applications.
Sandwich panels or Dibond panels are alternative names for aluminum composite panels, which are significantly lighter than solid metal sheets. Therefore, it can be easily processed, cut, and shaped using basic equipment. Furthermore, the installation and daily maintenance of sandwich panels are also simpler. For this reason, sandwich panels are ideal for exterior wall cladding, column wrapping, and other exterior decorative components, and are also suitable for making weather-resistant signs and sign brackets (especially in applications requiring intricate designs, such as decorative lettering).
Common Applications of Aluminum Sheets
Packaging
Aluminum sheets are frequently used in the food and beverage industry for packaging. Due to its good ductility and ease of processing, aluminum is an ideal metal for canned products. Aluminum is widely used in both food cans and thinner, lighter beverage cans. Aluminum does not rust, which is just one of its many advantages as a food and beverage packaging material. Aluminum cans were first used in 1957.
Vehicle Bodies
Aluminum sheets are a common material in the automotive industry for manufacturing car bodies and panels. Due to its lightweight properties, aluminum has become more prevalent than steel in modern car production.
Household Appliances
Aluminum is a common material for various household appliances such as washing machines, dryers, and refrigerators due to its lightweight, high structural strength, and good thermal conductivity. In addition, aluminum is also commonly used in the manufacture of electronic products such as mobile phones and laptops.
Cookware
Aluminum is the preferred material for many types of cookware due to its high strength and light weight. Furthermore, it has excellent thermal conductivity, making it ideal for cookware and pans that require even heat distribution.
How are Aluminum Sheets Produced?
Currently, aluminum is extracted solely from bauxite ore, which is found in clay-like soil several meters below the surface. Alumina, a white oxide powder, is produced by refining this ore in a hot solution of lime and sodium hydroxide. When alumina is combined with electricity and carbon (producing carbon dioxide) at high temperatures, it is converted into the liquid metal aluminum we know.
Depending on the final use of the metal, this liquid metal is processed into various ingots or alloys. Aluminum ingots can weigh up to 20 tons and be up to 20 feet long, and are typically used to manufacture tubes, rods, sheets, and angles. These aluminum ingots have excellent ductility (formability). Therefore, it can be easily rolled or pressed at different pressures and temperatures to produce aluminum sheets, plates, foils, and other products of various thicknesses.
How to choose aluminum sheet size?
Aluminum foil, sheets, and plates are available in a wide range of sizes globally. Aluminum sheets with a thickness between approximately 0.2 mm and 6.5 mm are typically classified as aluminum sheets and sold as plates, while thinner sheets are usually classified as aluminum foil and also sold as plates. Aluminum plates generally refer to sheets with a thickness exceeding 6.5 mm (approximately one-quarter inch).
The required degree of flexibility or rigidity for the sheet to perform its intended function will determine the best choice.
