||HIRA STEEL INDUSTRIES PVT. LTD.|
We, Hira Steel Industries Pvt. Ltd., are a leading manufacturer and exporter of HIRA TMT BARS. HIRA GROUP HAS STARTED TRADING IN M.S. STEEL PRODUCTS SINCE 1978. In THE YEAR 2000, we began our operations to manufacture M.S. TMT BARS & Round BARS (M.S. TMT Bars SIZES FROM 8 mm TO 40MM). A long span of experience in the steel business has led us to provide excellent sales and services to our valued customers.
At Thane, Maharashtra, we are working round the clock to maintain excellent quality standards, efficient delivery schedules, competitive prices and an excellent after sales service. We have managed to carve out a unique identity for our HYSD reinforcing Steel Bars produced at our manufacturing units. Our export markets are now present worldwide due to the admiration for our products from our customers.
We are the manufacturers and exporters of a wide variety of steel products like:
TMT (Thermo Mechanical Treated) High Strength Reinforcement Bars
- M.S. TMT BARS (Sizes M.S. Round 6 mm, M.S. Cat Bars 8 mm, 10 mm, 12 mm, 16 mm, 20 mm and 25 mm)
- TMT (Thermo Mechanical Treated) High Strength Reinforcement Bars.
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 tonnes.
Advantages of TMT Bars over Round 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.
Steel is the soul of almost every industry and today life without it is unthinkable. Name the product and there are cent percent chances of finding steel in combination with other elements or by itself. From the proverbial pin to submarines and high speed jets, steel has nowadays overtaken almost every aspect of life. In the household sector, steel has found a way in our kitchens, modern gadgetries and other items of utility. Understanding these facts we have given top priority to the kind of raw-material we process for our industries, and thereby manufacture superior quality steel for various industries.
Our stainless steel products are known for their superb quality. Reputed manufacturers of quality HYSD reinforcing steel bars, we make our products pass the most stringent tests at our company. Each bar is individually cold twisted; hence any invisible production defect is checked at pre-manufacture stage. Our steel bar products automatically survive the vigorous tests because of the installation of modern testing techniques at our company. Under the group 2nd license from Bureau of Indian Standards scheme, we manufacture high strength deformed steel bars at our manufacturing units.
Our company has the latest facilities compared with only the best in the industry. This coupled with a positive ambiance at our company and manufacturing units results in an excellent product line for our valued customers. We have at our company one of the most sought after productive and capable workforces. Technologically oriented, they work with an all round commitment and dedication to manufacture quality steel products. So, see for yourself, how our products can bring a great change in your business.
Manufacturing Process of Rolled Products- TMT Bars
The process involves converting the shape stock, viz. ingots, billets to the desired finished section in the hot condition by way of passing the material between a pair of grooved rolls and providing suitable drafts at various stages. The whole operation is conducted at a particular temperature range and within a limited time span. The stages of rolling operation comprises of heating of feed stock to rollable temperature, rolling the feeding stock in different mill stands, cropping the hot bar during the process of rolling between mill stands as applicable and subsequently finishing in form of hot rolled deformed bar in straight length. The hot bar coming out of the last pass is then conveyed through TMT line and collected in a cool bed after shearing. The bars at almost ambient temperature are sheared to commercial length stored and kept ready for dispatch.
In TMT process, hot bars are subjected to quenching by means of an intense cooling installation (cooling installation specially designed spray system). This step hardens the surface layer to martensite while the core structure remains austensite. When the bar is free of water chamber, heat flows from core to surface and the surface gets tempered to structure called martensite. In the cooling bed, due to atmosphere cooling, the hardened zone is tempered by temperature homogenization in the cross section and the austensite core is transferred to ductile-ferrite-pearlite core.
