Our facilities
A leveler line is an industrial system designed to correct the flatness of steel sheets by eliminating distortions such as coil set, crossbow, and edge wave.
A shear line is an industrial system designed to process steel coils by flattening and cutting them into sheets of specified lengths. This system enhances the material’s flatness and prepares it for various manufacturing applications.
