Ghaziabad Unit :

 TMT Steel High Strength Reinforcement Bars (Rebars)

TMT Steel high strength reinforcement bars (known as TMT bars) are manufactured under Thermex® patented technology. It is an economic, efficient and dependable concrete reinforcement suitable for all major reinforced concrete constructions such as buildings, bridges, reservoirs, roads, irrigation and power structures, dock and harbour structures, foundations, piles, precast concrete etc. It has been used with most satisfactory results the world over, in all major reinforced concrete structures for decades, and in tens of millions of tones.

Advantages of TMT Steel bars over traditional steel bars:

  • Greater yield strength.
  • Greater bond strength.
  • Satisfactory fatigue strength.
  • Satisfactory bendability.
  • Satisfactory weldability.
  • Lesser crack.
  • Better factor of safety due to hyper resistance.
  • Suitable both as compression and tension reinforcement.

WORD OF CAUTION !
Metallurgically, the TMT process is quite sensitive as it relies entirely upon achieving the required degree of hardening and tempering during hot rolling process for optimum results. Number of small steel rolling mills in the country, are manufacturing deformed bars just by passing the bars through water and selling them as "TMT Rebars". Such rebars may have strengths even lower than Grade Fe415 of CTD bars. It is therefore, well advised against use of material from such mills having sub-standard facilities without any genuine technological back up.

Certification

The TMT Rebar conforms to IS:1786/1985 grade, Fe-415, Fe-500 and Fe-550 for chemical composition, mechanical properties and dimensional tolerances. Material can be produced also as per international standards like DIN 488-BST500, BS444 Gr.450, ASTM-A615, GOST 5781-82 etc., or any special requirement of customers.

Stainless Steel Billets

The Steel Melting Shop of the company is equipped with Continuous Billets Caster. The stainless steel billets are produced in a ll standard sizes upto 200x200 mm 2 .  

Stainless Steel Wire Rods

The Ghaziabad plant of Rathi Steel And Power Ltd is equipped with the most modern facilities to manufacture quality stainless steel products. These facilities include induction furnace, AOD converter, Spectrolab and state-of-the-art wire rod mill. We produce Stainless Steel wire rod in 200 and 300 series conforming to following grades:

•  Austentic Stainless Steel: AISI-301, AISI-302, AISI-302B, AISI-303, AISI-304, AISI-304L, AISI-305, AISI-308, AISI-309, AISI-309S, AISI-310, AISI-310S, AISI-314, AISI-316, AISI-316L, AISI-317, AISI-321, AISI-347, AISI-348, AISI-384, AISI-386.

•  Martensitic Stainless Steel: AISI-410, AISI-414, AISI-416, AISI-420, AISI- 420F, AISI-431, AISI-440A, AISI-440B, AISI-440C.

These are the most versatile and most widely used stainless steel grades. It has excellent forming i.e. drawing and welding characteristics. It can be severely drawn without intermediate annealing. The austentic structure gives this grade excellent toughness, even down to cryogenic temperature.

 

Applications:

  • Food processing equipments particularly in milk processing and beverages making.
  • Kitchen appliances and equipments.
  • Woven and welded screens for mining, quarrying and water filtration.
  • Threaded fasteners and springs.
