Our Vision

To be the most trusted and reliable steel manufacturer in Sri Lanka.

GTB Steel was founded in 1999 as of the largest BOI ventures to manufacture and market reinforcement bars. The Company established one of the most modern and sophisticated rolling mills and under license from Tor-Isteg Steel Corporation, Luxemburg and Tor Steel Research Foundation of India, started manufacturing reinforcement bars under the brand GTB TOR.

In short span of time, GTB Steel established itself as a market leader in Sri Lanka producing reinforcement steel in sizes 8 mm to 40 mm confirming to SLS 375:2009 as well BS 4449:1990 standards. The Company is certified under ISO 9008:2008 management systems.

The Company was first to manufacture and market, in Sri Lanka, TMT (Thermo Mechanically Treated), the new generation Reinforcement Steel Bars with superior mechanical properties and economy in use over conventional Reinforcement Bars.

TMT Reinforcement Steel Bars are recognized throughout the world as superior construction steel compared to conventional Cold Twisted Deformed (CTD) Steel Bars with distinct advantages of higher bond strength, excellent bendability, superior weldability, higher corrosion resistance and other qualities.

With more than 200 cumulative years of experience in the steel industry, GTB Steel’s Management has been singularly focused on making the Company to achieve its vision – of the being the most trusted and reliable steel manufacturer in Sri Lanka.

GTB Steel uses the THERMEX Thermo Mechanical Process developed by QEK, Germany for production of high strength deformed bars that meet all the requirements of the civil engineering industry, viz. high yield strength, ductility, weldability and elongation values, which leading structural engineers expect from a technically superior processing technology.
