Rib Pattern for Superior Bonding Strength

STEELMAX TMX bar uses a rib pattern that uses in B500C rebars in British standards where the ribs shall alternate between a higher and lower angle with respect to the bar axis which yields a better bond strength. bars maintain the bond requirement more than as specified in the standard which increases the bond strength better with the concrete.

MECHANICAL PROPERTIES OF STEELMAX TMX

Due to high UTS/YS ratio(The higher UTS/YS Ratios is one of the important parameters for seismic resistance in steel reinforcement bars used in construction. It enhances the energy absorption capacity of steel before failure)and better elongation percentage, the STEELMAX BARS’ bendability and earthquake resistance properties are very high and guarantee high-level safety for ages. Bendability is very high which has an obvious advantage in the construction site

Why Us

Our Technology

Thermex QST

THE TECHNOLOGY

Thermex QST Technology

THERMEX TECHNOLOGY

All TMX steel rebars are TMT rebars, but all TMT rebars are not THERMEX/TMX rebars. Only those TMT bars manufactured using the licensed QST technology are TMX or THERMEX rebars. The structural uniformity is the highlight feature of TMX Bars. THERMEX process converts the bar surface to a hardened structure.

AI Cooling Bed

THE TECHNOLOGY

AI Cooling Bed

AI COOLING FOR UNIFORM STRUCTURE OF REBARS

The production phase involves cooling at ambient temperature to allow the hot core to temper the surface through the Thermex exchange. This results in a unique structure of tempered martensite periphery and fine-grained ferrite-pearlite at the core. This structure should be uniform throughout the cross-section of rebars.

BENEFITS OF STEELMAX TMX

Innovative & Enhanced Engineering

steelmax-favicon

SUPERIOR BENDABILITY

SteelMax Bars have a great degree of elasticity. These bars can be easily bent and molded into any shape. All the STEELMAX TMX bars undergo “bend test” and “re-bend test” as per the BIS Norms.

SUPERIOR WELDABILITY

SteelMax Bars have superior weldability which helps the architects and designers to build innovative and creative structures without affecting the quality of construction.

HIGH SEISMIC RESISTANCE

THERMEX Quenching & Self Tempering (QST) Technology and state of the art manufacturing process ensures a minimum elongation of 18-20% for steelmax- which is 50% more than the basic BIS requisite.

HIGHER FATIGUE STRENGTH

SteelMax Bars are highly ductile and have a super-strong surface layer. These properties help in withstanding fatigue for a longer period. Fatigue strength is affected by corrosion. The enhanced elongation translates into greater ductility.
