How Can Aluminum Profiles Be Classified into Different Types? 

Depending on the application, aluminum profile types might vary substantially. Profiles or cross-sections can have a wide range of thicknesses, which is essential in providing shape or function to a particular construction. Manufacturers have benefited considerably from using aluminum material in profile fabrication, owing to its numerous qualities. It’s malleable, light, and highly adaptable. It also offers a lower-cost option for increasing the durability and foundation of a particular construction. 

Metal extrusion is commonly used to create aluminum profiles. This entails inserting an aluminum billet into the tooling die with precise cross-sections. The resulting extruded product can be in either little or more extended portions, as both are conceivable. With this in mind, the various varieties of aluminum profiles can be considered the result of the extrusion process. Continue reading to find out more. 

What is an Aluminum Profile? 

Aluminum profiles are the shapes of extruded aluminum goods that include trim caps, rods, angles, bars, and channels, to name a few of the many configurations and sizes that aluminum profiles can take. Profiles can be extruded hot, cold, or warm through a profile-specific die. Standard profile designs are commonly utilized; however, you can specifically create profiles for special needs. Aluminum alloys 6061, 6063, and 1100 are the most commonly utilized in manufacturing profiles. 

The profile is significant in the extrusion process. The billet or log that is driven through the die forms a shape known as the profile. Significantly, the design of the profile is created during the design phase, which determines its proportions and shape. Over the years that extrusion has been employed, a wide range of hollow, solid, and semi-hollow profiles have been developed. 

The profile is carefully selected for its application before manufacture. Its shape is carefully forged into the die to fulfill its design requirements. Once the profile and die-cast are approved, they are applied to the application process, and the product or part is manufactured. 

Aluminum Framing 

Aluminum framing systems are modular systems made up of extruded aluminum sections. They include components used to construct machine frames, jigs, and other industrial items. Most aluminum framing systems necessitate the installation of aluminum framing components formed into profiles. Selecting an aluminum frame system necessitates a thorough examination of product specs and supplier capabilities. 

Door Section 

Aluminum door sections, often called the ED section, are profiles used in heavy-duty glass doors for structures. They are a component of the overall mechanism of push doors and frequently function as a whole system. 

You can find glass doors with a push mechanism in various business settings. Its indisputably classic design emphasizes both form and practicality. Aluminum door pieces help to keep the glass in place and prevent it from collapsing or toppling over. 

Square Profile

Square aluminum profiles are a subset of hollow-beam aluminum. They’re utilized in comparable applications as hollow beams, with the main difference being that they can provide more robust support. 

You can find square profiles in wall load bearings, support columns, and pillars. Depending on the manufacturing technique, they can be created either seamlessly or non-seamlessly. This entails a non-time-consuming method of continuously flattening an aluminum sheet and attaching the corners to make a square. A high-pressured piercing tip is passed through the center of the profile to smooth out the inner edges. 

RCW Profile 

RCW profiles are common in high-rise buildings and are typically used on curtain walls or mullions. These typically have little structural function because their primary purpose is to provide a barrier to keep environmental elements from entering a building. 

Curtain walls are typically aluminum-framed and come in a variety of sizes. These profiles must include the components required to prevent undesired things from entering the interiors of the building space. This is one of the primary reasons why RCW profiles are typically equipped with other materials to prevent leaks. 

Hollow Beam

The term “hollow beam aluminum profiles” refers to a hollow aluminum beam with no particular cross-sections. These are typical of modular installations, particularly in architectural design. 

You can find hollow aluminum beams in various shapes, each with its sub-classification. These can be rectangular beams, square beams, or ones with a hollow top/bottom. As a result, a beam that can be employed as part of a support framework for buildings, bridges, and other industrial applications has been created. They are essential for horizontal support, especially when dealing with heavy weights. 

SD Aluminum Profile

Aluminum profiles are helpful in both large-scale and small-scale applications. They’re frequently used as part of the framing of windows. Aside from its lightweight and flexible nature, aluminum’s resistance to corrosion is one of the reasons metal can be used to make robust window frames. 

SD profiles are ideal for sliding window frames. Windows are continually exposed to many substances in the outside environment, such as dust, rain, and extreme heat. The SD profile’s sliding capability and its resistance to many types of weathering make it the perfect choice. 


All aluminum profiles’ many forms help give function, support, structure, and stability. Manufacturers have included custom-fit changes to these profiles to enable various applications, including sliding doors, window sections, louvers, and building frameworks. Aluminum’s application in construction has progressed beyond only providing structural support and beyond protecting from the elements. There is little doubt that these extruded profiles are one of the most long-lasting applications for aluminum.
