In mid-April, Pangang's vanadium plate mill successfully produced photovoltaic zinc-aluminum-magnesium product S550GD for the first time, with product quality fully meeting user requirements. In recent years, with the support of the research institute and related departments and units of Pangang's vanadium, the mill has gathered resources from various aspects such as technology, equipment, and chief experts to vigorously carry out research and development of photovoltaic steel products. It has successively completed the development and mass production of S250GD, S350GD, S420GD, and S450GD products. The successful development of the S550GD product signifies that Pangang has already possessed the production capacity for a series of photovoltaic products.
