Product NewsNew EDI Light capabilities allow late specifications of colours and coatings
7 July 2020Ever since ArcelorMittal first introduced SteelUser a decade ago, we have continued to develop our digital tools in collaboration with customers. SteelUser itself has evolved to become a multi-platform communication channel, enabling customers to interact with ArcelorMittal via apps, web services, and electronic tools integrated into their business systems. This has made it possible for customers to get production information, send orders directly to ArcelorMittal, and receive invoices and related documents electronically.In a recent project with Polish customer Inter-Max, ArcelorMittal has added the ability to specify the coating and colour of a product late in the order process electronically. Inter-Max, which uses ArcelorMittal’s EDI Light service, now has full transparency over its orders and can respond quickly and efficiently to demands from their own customers.
