Tiger TMT Iron Rods are produced by 3 different companies of the African Industries Group (AIG) - African Foundries Limited (AFL), African Steel Mills and Abuja Steel Mills. All their 7 manufacturing plants have state-of-the-art high-tech facilities engineered by Western European and Far Eastern suppliers. AFL is the only steel company in Nigeria with UK CARES, ISO 9001, ISO 14001 and ISO 45001 accreditations.
Tiger TMT is aligned with American standards and is available in all sizes. Known for its proven strength, Tiger TMT has become a trusted brand in the Nigerian market. We are committed to providing the best quality iron rods while conforming to international standards. Tiger is a Thermo-Mechanically-Treated (TMT) rebar, rolled from high-quality low-carbon (below 0.24%) billets. BOF refined liquid steel is routed through a PLC-controlled LRF before being cast into billets on a continuous caster.
These high quality billets are heated in a PLC controlled fully automatic reheating furnace and then passed through a continuous, centrally controlled, fully automatic state of the art rolling mill. Adhering to the international practices of rolling, the mill applies very gradual sectional reduction and accurate temperature control of rolled stock, thus ensuring very consistent product quality.
Tiger being a TMT bar, gets water quenched immediately after exiting last strands of finishing rolls. Water flow and related parameters to this quenching box along with the stock speed are kept under strict control with the help of a PLC controlled closed loop system. This ensures consistency in product quality.
Microstructure transformation during quenching and subsequent cooling process ensures a gradual change from the surface to the core of the rebar. Theo outer layer is very tough and strong whereas central layer is softer and more flexible.
African Foundries' lab is equipped with all necessary facilities to conduct in house testing of Tiger TMT during the production process.
Tiger TMT is subjected to all necessary mechanical and chemical tests to confirm quality on a regular basis.
Tiger TMT rebars are supplied with necessary test certificates for mechanical and chemical properties on demand.
Tiger TMT is aligned with American standards and is available in all sizes.It is a trusted brand in Nigeria, committed to ensuring quality always.
