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

Aluminium Conductors Steel Reinforced (ACSR conductors), as the name suggests, consist of a solid or stranded steel core surrounded by strands of Electrolytic grade aluminium. The steel core imparts high mechanical strength to ACSR conductors, which are therefore suitable to be used for river crossings, overhead transmission lines, installations involving extra long spans etc. For any given resistance, ACSR conductors can be manufactured having a wide range of tensile strength as per customer requirements. The principal advantages of these conductors are high tensile strength and high mechanical strength to weight ratio, and therefore they are used for longer spans with fewer supports and lesser sag at a given tension. ACSR is preferred for it’s capacity to withstand extreme wind loads. Due to the greater diameter of ACSR conductors corona losses are low, resulting in substantial savings in high as well as extra high voltage overhead transmission.

Key Benefits

• ACSR conductors have high tensile strength.
• HIgh mechanical strength to weight ratio.

Standards

We manufacture ACSR conductor as per following standards

• BS 215 Part 2
• DIN 48204
• IEC 209
• ASTM B232 : 1981
• IS 398 Part 2 & 5

MIG (Metal Inert Gas) welding wire is used in Gas Metal Arc Welding along with a shielding gas. MIG wire is produced adhering to the highest quality standards with ER70S-6 specifications. Some of the salient features that our MIG wire offers are as follows:

• Available in layer winded spool for trouble free continuous operation without entanglement.
• Controlled Cast and Helix
• Excellent copper adherence
• Optimum copper coating for efficient current pick up and freedom from rusting.
• Available in 0.8mm and 1.2mm wire diameters

Aluminium Stranded Conductors (ASC) better known as All Aluminium Conductors (AAC) are manufactured from electrolytically refined (E.C.Grade) aluminium, containing a minimum of 99.5% aluminium by weight. The aluminium used has a minium conductivity of 61%. AAC conductors are used mainly in urban areas where the spacing between supports is small and thereby the supports are relatively closer to each other.

All Aluminum Conductors are made up of one or more strands of aluminum wire depending on the required current carrying capacity and used specially as bus conductors at sub-stations. AAC conductors are also used extensively in coastal areas because they have a very high degree of corrosion resistance.

Key Benefits

• Conductivity of AAC conductor is high.
• AAC conductor is corrosion resistant.

Standards

We manufacture AAC conductor as per following standards:

• BS 215 Part 1
• DIN 48201-5
• IS 398 Part 1
• IEC 207
• ASTM B231 : 1981

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.
