Acerinox Group

Three 20-high mills in MonoBlock design

The Spanish Acerinox Group is one of the world’s largest stainless steel producers. Ever since 2012, Bahru Stainless SDN BHD, a member of the Acerinox group, has operated a 20-high mill in Malaysia supplied by SMS group. The plant is integrated in the new cold strip complex in Johar Bahru. Just a few years later, in spring 2015, the Acerinox Group awarded us a contract for another 20-high mill for its subsidiary North American Stainless (NAS), USA. NAS is erecting the USA’s most advanced and powerful production facility for bright-annealed steel strip in Ghent, Kentucky. Now Acerinox is investing in its main production facility in Los Barrios in Cadiz, Spain. There, SMS group is due to install a new 20-high mill complete with X-Pact® electrical and automation systems.
