The staff of the central repairs shop at Saba Steel Complex has relied on the capability of local producers to develop and overhaul two lower shells for the complex's electric arc furnace.

Staff then gathered preliminary data on the furnace shell and procured, inspected and confirmed the specifications of the steel sheets needed for the overhaul and identified capable local companies.
