Hot-rolled profiles are created from steel heated to 900 - 1,000 degrees Celsius, making the material ductile and moldable. The steel passes through a series of rollers to achieve its final shape and size, followed by a stress-relief process to remove internal tensions. This results in profiles with high strength parameters, crucial for industrial and construction applications.
Advantages of Hot-Rolled Profiles
Homogeneous Internal Structure: Consistent impact and tensile values across the entire surface, including the weld zone and corners, ensure reliable test results and high safety margins.
High Load-Bearing Capacity: Strong resistance to bending and deformation, suitable for intensive loading.
Ductility: Greater ductility compared to cold-rolled sections, retaining considerable resistance even beyond the upper limit.
Enhanced Weldability: Less rounded corner shape allows for smaller corner radii, increasing the weldable area, important for structural applications.
