L-shaped profiles and angles in grade S275JR or S355JR are steel profiles with an L-shaped cross section. These profiles are commonly used in the construction industry to create frames, bridges and metal structures. Thanks to their L-shape, L-shaped profiles and angles can increase the rigidity and structural resistance of the structures in which they are used. The choice of steel grade depends on the specific needs of the project, including the expected workload and environmental conditions to be faced.
