Uprofiili

Uprofiili, or U-profile, is a metal profile with a U-shaped cross-section used as a structural channel in engineering and construction. The U-shaped cross-section forms a channel that can be attached to other components with screws, bolts or welding, providing stiffness in one direction while offering straightforward mounting along its length. U-profiili are common in steel, aluminum and other materials and are used as framing members, tracks and supports in a wide range of applications.

Materials and production: U-profiili are manufactured in carbon steel, stainless steel, aluminum, and sometimes in plastics. They are typically galvanised or powder-coated to improve corrosion resistance. Steel versions are usually produced by roll forming or other cold-forming processes; aluminum profiles are commonly produced by extrusion. Lengths generally range from about 2 to 6 meters, depending on material and supplier, with thicknesses varying from roughly 0.8 mm to several millimeters in heavier structural uses.

Sizes and specifications: A wide range of flange widths, web heights and overall depths exist, with dimensions and tolerances governed by regional standards and manufacturer practices. Availability and naming may differ by country, but the basic concept remains a U-shaped channel used for mounting, framing and support.

Applications: U-profiili are employed in construction and manufacturing for structural framing, mounting channels and tracks, window and door frames, guide rails, cable-management channels, solar mounting systems, furniture components and automotive trim. They are valued for their combination of stiffness, versatility and ease of assembly.
