About Us

Company profile

Perfect TMX TMT is Bhutan’s sole manufacturer of Thermex TMT reinforcement bars and one of the largest such manufacturers in the north-eastern part of the subcontinent. The company was established in 2014 as an integrated private sector company embodied of three experienced and technically sound pioneers, namely Lhaki Steels and Rolling Private Limited, Bhutan Rolling Mills Limited and Bhutan Steel Industries Limited (Druk Iron and Steel Limited).


Located at Pasakha (Phuentsholing), our facilities use a computerized German technology called THERMEX quenching system technology to produce high strength construction re-bars through processes of quenching and self-tempering.

Perfect TMX TMT produces top quality reinforcement bars under the brand name, Perfect Thermex TMT, under Grade FE500, to match any international standards. Our re-bars come in sizes of 8mm, 10mm, 12mm, 16mm, 20mm, 25mm, 28mm, 32mm, 36mm & 40mm of Fe 500 grade.  We also produce a range of products such as plain bars, wires and nails of various sizes.

Every batch of thermex re-bars that rolls out of our mills undergoes the most stringent physical and chemical tests. Quality is the hallmark of our products. And this is not merely an empty slogan. A serious business like ours ensures there is no room for empty sloganeering. In a region prone to frequent earthquakes and seismic activity, we remain well aware that a single faulty rebar can result in unimaginably horrific consequences; and we will never allow ourselves to be the cause of any such misfortune. In other words, we can sleep well only when you do. At Perfect TMX TMT, we value safety and social responsibilities.

Quality is not a statement at Perfect TMX TMT. It is a way of life. Today, our re-bars are approved for supply to major hydropower projects in Bhutan and to the eastern and north-eastern states of India. Recognised for quality, our re-bars are considered at par with reputed steel manufacturing brands in India. Our rolling mills are certified under BIS (IS 1786:2008), ISO 9001, Bhutan Standards Bureau, and THERMEX.
