SG Mart is not manufacturing – The manufacturer (Tata/JSW/NMDC/Jindal) will provide all required certificates as per grade of Steel.
They are only facilitating large scale “buying/selling – Trading of Steel, Logistical and warehousing”, may be in future other Construction material, once they scale Steel business.
An example of this can be seen in the zinc trading business where the company has already become the largest player _ Refer Concall.
They identified one key service missing in the steel (Construction) infra space and setting up building blocks – Similar services/companies in large scale exists in other parts of the world, as shared above in one of the post.
Execution and commodity price are the major risks here.
