• Perfect TMX TMT Established in 2014, Perfect TMX TMT is the flagship unit of the Perfect Group. Located in Pasakha, Bhutan.
• Bhutan’s sole manufacturer of THERMEX TMT reinforcement bars.
• One of the largest such manufacturers in the northeastern subcontinent.
• Employs computerized German THERMEX technology for state-of-the-art quenching.
• Produces high-quality FE500 grade reinforcement bars.
• Available in a wide range of sizes from 8mm to 40mm.
• Also manufactures plain bars, wire coils, wire nails, and binding wire.

Perfect TMX TMT re-bars are manufactured using high-quality billets that are manufactured in-house at a contemporary integrated steel plant. Our re-bars are produced using a direct hot charging process where the billets from the continuous casting machine are directly fed at uniform controlled temperature to a rolling mill. This ensures consistent quality of re-bars as identical heat treatment is dependent on uniform re-bar temperature.

The strength of the re-bars are vigilantly controlled by optimizing the water pressure for their pearlitic core and tough surface of tempered martensite, thereby providing ideal strength, ductility and toughness.

Perfect TMX TMT Bars are thermo-mechanically-treated in a state-of-the-art Thermex Quenching Technology for consistent yield strength. In this process, high-pressure water jets rapid quench the hot bars under after they roll out of the last finish mill stand. The bars cool, allowing the core and surface temperatures to equalize. After decelerating cooling to room temperature, the re-bars turn into a ferrite-pearlite aggregate. These processes guarantee properties of superior stability, durability and easy workability.

Perfect TMX TMT offers the widest range of re-bars that can be used in any type of civil construction, from modest RCC buildings to mega hydropower projects. Our range of TMT re-bars meet even the rarest needs of a civil engineer.

Features of PERFECT TMX TMT

PERFECT TMX TMT Re-bars Fe 500 is manufactured under precise process conditions that assure increased strength. Our re-bars are ideal for applications in heavy load RCC structures like fly-overs, hydropower dams, bridges and other critical structures where high yield load (design load) is required without compromising on ductility. In addition to these features, Perfect TMX TMT re-bars exhibit the following characteristics:

• Superior strength combined with high ductility;
• Excellent weldability without loss of strength at welded joints;
• Better ductility and malleability;
• Earthquake resistant;
• High thermal resistance; and
• Significant savings in cost of steel.
