In hot rolling mills the steel bar is passed through a high pressure water quenching system whereby only the peripheral temperature is drastically reduced while the core remains largely unaffected. On leaving the specially designed quenching system, the core heat tempers the peripheral martensite that was formed during quenching. This results in a rebar with a soft core and a uniform hardened tempered martensite periphery - a rebar with high yield strength but with extremely good ductility. Such rebars are ideal for use in high hazard seismic areas.
These bars are produced in bar rolling mills by use of the globally proven and accepted THERMEX Quenching System and Technology of M/s HSE Germany.
In the Indian Region comprising India, Nepal, Bhutan, Bangladesh, Myanmar, Pakistan and Sri Lanka, M/s H&K Rolling Mill Engineers Pvt. Ltd., Mumbai (H&K India) have been given perpetual exclusive rights by HSE Germany to Licence, sell, market, install and commission the unique THERMEX Quenching Systems. As on 1 April 2013, H&K India has received orders for nearly 200 Thermex Systems to be set up in rolling mills - of which about 29 were under excecution. The installed capacity of Thermex QST rebars in India alone is over 14 million tonnes (65% market share). Each Thermex Licensee in Indian Region is subject to strict quarterly audit. Qualified QST engineers visit each Licensee to ensure that the rebar properties are as per the strict standards laid down by HSE Germany and H&K India besides meeting the Standrards of the country.
The Thermex 500 QST rebar meets most global standards and codes and is widely accepted by leading users of rebars because of the uniform properties obtained from the various Thermex Licensees.
In India, the registered trade mark/name THERMEX is owned by H&K India as per permission given by HSE Germany.
Unfortunately, in India, these QST rebars are incorrectly referred to as 'TMT' bars. 'TMT' is an acronym for Thermo-Mechanically Treatment even though no mechanical treatment is involved in the process. This has lead to a number of improper 'TMT' rebars being sold in India with non-uniform tempered martensite periphery at the rebar cross-section - encouraged by this non-uniformity "not being a ground for rejection" as per latest rebar code IS:1786-2008!

What else can I help you with?
Rebar is used to?
Rebar is used to reinforce concrete, helping it resist tensile stresses, control cracking, and increase the strength and durability of structures such as buildings, bridges, slabs, columns, and foundations.
What makes up rebar?
Rebar is a steel bar or mesh of steel wires used in reinforced concrete, and reinforced masonry structures which helps to strengthen the concrete under tension. Steel is melted down to liquid form on extreme amount of heat and then to give the rebar its shape, the liquid steel is pulled through small round openings. The developers choose to purchase higher-grade material for safety which prevent the concrete form from cracking. After the steel has its shape, the manufacturer will make the twists, and grooves on the metal to check if it will stay firmly in place inside the structure. The ends of reinforced metal bars are covered with plastic caps to prevent harm to construction workers as they are dangerous while installing. Now rebar is distributed from manufacturer to the job site and then the product is bent to the proper specs with the help of specialty hydraulic benders and cutters. There are only a few type of rebar that can be welded and that is the reason many construction companies use wire and coupling splices to join the ends together.

How do you write details of plinth beam?
To write details of a plinth beam, start by specifying its dimensions, including width, depth, and length, as well as the material used (typically reinforced concrete). Include reinforcement details, such as the type and placement of rebar, along with any necessary cover specifications. Additionally, provide information on connections to columns and walls, load-bearing capacities, and any relevant codes or standards to ensure structural integrity. Finally, include construction notes and any specific design considerations, such as drainage or moisture barriers.

What is rebaring?
Rebar Detailing is a procedure of making shop drawings for the steel reinforcement for the development procedure. The Rebar Detailing procedure incorporates the position, bending shapes, amount, description, laps of the reinforcing steel and measurements. The Rebar Detailing Drawings are made to incorporate the separating, area, rebar size and lap of steel. The Rebar Detailing Services includes: Rebar Detailing Services, Rebar Shop Drawings Services, Rebar fabrication Services, Rebar Framing Plan Design, Rebar Structure Foundation, Rebar Pit Design, Rebar Framing Plan, Rebar Beam Design, Rebar Structure Steel Detailing, Structure Foundation Rebar Detailing.

What is rebar detailing?
Rebar detailing is the process of creating detailed drawings and schedules that specify the placement, dimensions, and quantities of reinforcing steel (rebar) in concrete structures. These drawings serve as a critical guide for contractors, ensuring that the reinforcement is installed correctly to provide strength and durability to concrete elements like beams, columns, slabs, and foundations. A well-executed rebar detailing package includes: ✔ Bar bending schedules (BBS) – listing shapes, sizes, and quantities ✔ Placement drawings – showing exact rebar positioning ✔ Material specifications – including grade, spacing, and lap lengths ✔ Anchorage and splice details – for proper load transfer Poor detailing can lead to construction errors, safety risks, and costly rework. This is why many firms rely on specialized providers like Silicon Engineering Consultants, which combine engineering expertise with advanced BIM tools to deliver error-free, constructible rebar details that comply with international codes (like ACI, BS, or IS).
How to lay rebar for concrete effectively?
To lay rebar for concrete effectively, follow these steps: Determine the required rebar size and spacing based on the project specifications. Place the rebar in the correct position within the formwork, ensuring it is properly supported and secured. Use tie wire to connect and secure the rebar at intersections and corners. Use chairs or supports to lift the rebar off the ground to the desired height. Double-check the placement and alignment of the rebar before pouring the concrete. By following these steps, you can effectively lay rebar for concrete to ensure a strong and durable structure.
