Product
Indus 555-D TMT
Indus has pioneered in manufacturing a new dimensional TMT rods called Indus X ribbed TMT. These bars give Xtra strength and xtra safety to the construction. Since Indus X ribbed is a premium product, the customer will have the following benefits
Features
Xtra Bonding
The unique pattern of X-Ribbed provide more ribbed area for concrete mixture to bond with the steel rod, enhancing the strength of the buildings.
Xtra Elongation
Indus X ribbed rods have the Xtra benefit because of higher ductility which will suit any kind of construction.
Xtra Safety
The added strength (Proof strength and Ultimate Tensile strength) to the steel rods helps in more safety for the buildings.
