Profiles and Structural Shapes

Profiles and structural shapes are shaped stock forms with uniform cross-sections. Examples include tees, angles or beams manufactured through extrusion, continuous casting, roll forming, and other manufacturing processes. Profiles and structural shapes are used in a variety of engineering and construction applications. Many types of structural steel shapes and aluminum structural shapes are available. Accuracy is an important consideration in that a structural steel shape or aluminum structural shape often needs to fit precise dimensions or support heavy loads. Typically, profiles and structural steel shapes are formed securely to satisfy various strength requirements. As a rule, the die design for an aluminum structural shape determines the precise cross-sectional dimensions of the shape or profile.

Profiles and structural shapes are available in a variety of shapes and sizes. Solid, hollow, and semi-hollow products are commonly available. Some suppliers specify a profile and structural shape product in English design units such as inches (in) or feet (ft). A metric structural shape may be specified in centimeters (cm). For best results, the profile of aluminum shapes and steel shapes must adhere to the limitations of the extrusion, continuous casting or roll forming process used in production. Similarly, plastic structural shapes need to conform to the original plastic plate sheet profile shape. Ultimately, the characteristics of a structural shape are determined by the cross-sectional view. Selecting profiles and structural shapes requires an analysis of how cross-sections can be adapted to the construction of the final architectural form.

Profiles and structural shapes can be very simple or relatively complex. Structural steel shaped beams are often used in the construction of larger buildings, such as shopping malls and sports arenas. They are also used in highway construction projects such as bridges and overpasses. Many structural steel shapes and aluminum structural shapes can be custom-designed. Manufacturers of profiles and structural shapes are located across the United States and around the world. They differ not only in terms of capabilities, but also in terms of approvals, certifications, and industries served.
