What Can Be Done with Sigma Profiles? Sigma profiles, made primarily from aluminum, are lightweight, durable, and modular structural elements that cater to various design needs. The grooves on their surfaces enable easy installation of screws and other fasteners, making them versatile for a wide range of applications. These profiles are especially preferred for building modular structures, machine frames, and assembly systems. Here’s a detailed look at their primary uses and advantages: 1. Machine Frames and Structures Sigma profiles are widely used in constructing machine frames and structures due to their strength and flexibility. Applications: CNC machines, 3D printers, laser cutting machines, and other industrial or semi-professional devices. Advantages: The lightweight nature of aluminum provides portability while offering stability. These structures can also be quickly disassembled and reassembled when needed. For instance, a CNC machine frame built with sigma profiles ensu...
