As is well known, the roof beams used in rail cars and subway carriages have unique shapes, with precise dimensional errors below millimeters, and require high surface quality. After countless research and experiments, Beijing Shengda Weiye Profile Bending Factory has finally successfully cold bent the curved beam (stainless steel) of rail transit passenger cars, and mass produced and delivered it to customers.
