Since its inception in 1992, Gulf Steel Industries Co. Ltd (GSIC) has consistently strived to enhance its products and services through continuous development of advanced technologies in-house. In our quest to achieve sustainable development, we have focused on placing environmental, health and safety issues at the forefront at all times.
A pivotal part of the Al Nasser Industrial Enterprises L.L.C Group, Gulf Steel has, over the years, played a prominent role in ensuring we are always at the top of our game. In line with our global aspirations, Gulf Steel has expanded its customer base beyond the boundaries of the UAE and caters to customers in other rapidly growing markets across the GCC region.
Gulf Steel is 9001:2008 Certified and manufactures hot rolled low carbon steel (Deformed Steel Bars) through Thermo Mechanical Treatment process (QST) in sizes ranging from 8 mm to 32 mm and in lengths of 12 meter. We also produce Plain Bars, Square
Bars and Welded Mesh. Gulf Steel is currently capable of rolling out 120,000 TPA of Deformed Steel Bars, 36,000 TPA of Cold Ribbed Bars in coils and cut to length, as well as 15,000 TPA of Welded Mesh.
The exponential growth witnessed by Gulf Steel in such a short span of time has presented us with a unique opportunity to expand our capacities, diversify the scope of operations and expand the purview of our product offering. In order to realize this vision, Gulf Steel has planned a state of the art rolling mill in ICAD II, Mussafah, Abu Dhabi. The plant will have a capacity of 400,000 TPA and is scheduled to be commissioned by Q2 of 2011.
Gulf Steel has also launched two primary subsidiaries to help further develop and enhance the product offering. The two new entities Emirates Steel Co. L.L.C (Billet Manufacturing) and Gulf Sponge Iron Co. Ltd (D.R.I Manufacturing) have been established to cater to a wider customer base in UAE and abroad.

MANUFACTURING PRoCESS
Gulf Steel Industries produces Deformed Steel Bars from prime quality billets manufactured by our sister companies Emirates Steel Co. L.L.C & Emirates Steel Establishment. After receiving the billets and inspecting them, they are stacked according to the cast numbers. Pre-sized billets are charged to a pusher type, temperature-controlled Re-heating Furnace.
The heated billets are passed through various stands to arrive at the desired size. From the finishing stand, the bars are passed through a Thermo Mechanical Treatment (TMT) process whereby the hot bar get rapidly cooled by water to achieve a high strength with high ductility. Due to rapid controlled cooling, surface temperature of bar reduce drastically and form martensite structure and core of the bar remain fine grain ferrite perlite. This provides the higher strength and ductility to the finished material.
Bars are cut by a Flying Shear in the required length and passed through twin channels to a walking beam type cooling bed. The cooled bars are scored by using a finishing shear as per the standard length (12 meters), bundled (2 tons) and sent for keeping in the finished goods storage area.

Gulf Steel produces high-grade TMT construction rods. The mill is technologically advanced and uses semi-automatic rolling to ensure the quality. Due to the low carbon content and strict quality controls, the TMT process bars do not lose strength at the weld joints, are highly flexible and provide top-grade elongation. The special design of the bars allow for excellent bonding properties and a longer life.
