profilbau

Profilbau, or profilbauweise, is a construction approach based on standardized metal profiles that are joined with connectors to form frames, supports, and enclosures. The profiles are typically aluminum or steel, often extruded with T-slots or similar grooves that enable modular assembly without bespoke machining. This enables rapid construction, easy reconfiguration, and scalable systems for a wide range of applications.

Historically, profilbau emerged in industrial settings where modular framing and machine guarding required flexibility and reuse. Over time it expanded into architectural components such as partition walls, curtain-facade subframes, display systems, and exhibition stands. The technique is valued for its ability to combine rigidity with light weight and to integrate with hardware, glazing, and automation components.

Materials and components commonly used include aluminum and steel profiles in various cross-sections, corner brackets, end-mounts, fasteners, sliding or hinged connectors, and gaskets or seals for enclosure systems. Profiles often come in standard sizes (for example in 20x20, 30x30, or 40x40 mm ranges) and are designed to be compatible across manufacturers, enabling mixed-component assemblies.

Applications span office interiors, industrial plants, workshop and laboratory furniture, automation equipment frames, safety fencing, and display or exhibition structures. Advantages include high strength-to-weight ratio, modularity and reusability, precise tolerances, and straightforward assembly or disassembly. Limitations may involve higher material costs for low-volume use, aesthetic constraints compared with custom carpentry, and performance limits for very high-load or highly specialized conditions.
