Lprofiilit

L-profiilit, or L-profiles, are angular metal sections with two legs that meet at a right angle. They are widely used in construction and metalworking for framing, bracing and supporting structures. L-profiilit can be symmetric (equal legs) or asymmetric (different leg lengths).

Materials and manufacturing: They are produced in steel (hot-rolled, galvanized, or stainless), aluminum and other alloys. Steel angles are usually hot-rolled or cold-formed; aluminum angles are often extruded. The profiles are defined by leg lengths and thickness, typically written as L a x b x t, where a and b are the leg lengths and t is the thickness.

Properties and variation: The weight per meter and stiffness depend on the material and dimensions. Typical engineering calculations use the cross-sectional area and moments of inertia, with density approximately 7.85 g/cm3 for steel and 2.70 g/cm3 for aluminum.

Applications: Used for mounting frames, supports, brackets, and reinforcements in machinery, furniture, shelving, and civil construction. They are also used as corner reinforcements and in lightweight structures.

Standards and procurement: Sizes and tolerances vary by manufacturer and region; buyers refer to supplier catalogs and relevant standards (often EN standards in Europe). Finishes may include painting, galvanizing, or powder coating.
