Bozhong Group is able to supply all kinds of structural steel produced by En10025-2 standard, which mainly includes 4 major grades: S235, S275, S355 and S450, there's also more specific steel grades for different mechanical properties. As same as common structural steel, steel plate and pipes under this standard are featured with good weldability, formability, hot forming, cold formability, flangeability, roll forming, and suitable for hot dip zinc coating.
Scope: En10025-2 is European standard which specifies the technical delivery conditions for flat and long products(includes steel plate and steel pipes),and semi-finished products which are manufactured for further processing of hot rolled non-alloy quality steels in series of grades and qualities.
Application: Steel Structure: bridge components, offshore structures, Power plants Mining and earth-moving equipment Load-handling equipment Wind tower components, etc.
