Tricon

Our brand of construction steel is a high strength steel bar where the diameter of the reinforced bar is lowered without compromising in strength of the reinforcement leading to substantial savings in steel and cost.

Thermo Mechanically Treated bars (TMT bars) replaced CTD bars in the late 1990s as they were considered technically superior and also

convenient for the rolling mills. Post production cold twisting was a cumbersome, time consuming and labour intensive job and often a bottleneck in production.

“TRICON”, high strength deformed bars conforming to IS : 1786 - 2008, in Grade Fe 550 corresponding to DIN : 488 and BS : 4483 are

manufactured by using the well-established technology of simultaneous cold rolling and cold ribbing.

Metal Liners is a railway component used as packing between the Elastic rail clip and the foot of the rail while laying tracks. Liners have high durability, dimensional stability and the ability to withstand different weather conditions.

Specifications - T 3738, T 3740, T 3741 & T 3742

Steel rounds have a diverse application, they as used by forging industries, bright bar industries, auto-ancillaries, foundation and anchor bolts, pins, rollers, bushes, and many more engineering industries.

Specifications - Sizes manufactured by us ranges from 20mm to 45mm.

Hot-rolled strips offer extensive performance characteristics, versatility and economy, in addition to having dedicated properties for specific applications. We manufacture strips mainly to cater to the ERW Pipe industry. Our strips are also used for general engineering purposes like manufacturing cable supports, etc.

Fish plates are used in railway construction, it is a metal bar that is bolted to the ends of two rails to join them together in a track. The top and bottom edges are tapered inwards so the device wedges itself between the top and bottom of the rail when it is bolted into place.

We manufacture 8 types of fish plates as per designs of Indian Railways, however, we are equipped for custom made designs as per other specifications.

Hot rolled flats have their primary use in steel fabrication and general engineering purposes.

Specifications - Sizes up to 150 mm in width.

We manufacture stick welding electrodes of consistent quality conforming to international standards. Apart from having a versatile product range, we also aim to offer customized solutions to distinguish our products.
