Most of the time people use stones and concrete pieces to raise the steel bars during the time of concreting which is not at all recommended. This will reduce the strength of concrete. In addition to this, using stones with different shapes will cause un-even slanting to the concrete surface and in turn shifts to one side to create voids. Kalliyath brings an end to this with Kalliyath Cover Blocks with zero void design. Kalliyath Cover Blocks prevents chances of creating voids and thus increases the strength and durability of concrete surface.
KALLIYATH PRESENTS COVER BLOCKS WITH ZERO VOID DESIGNWHAT IS ZERO VOID DESIGN?The sophisticated design created by experts after scrutinizing several possibilities to strongly hold the steel bars keeping them still at a point with the desired height without slipping away is known as Zero Void Design.
BENEFITSSince Kalliyath Cover Blocks with Zero Void Design keeps the steel bars strongly on its proper place, the full strength of the reinforced concrete can be achieved. The Cover Blocks can be used for concreting steel bars with 8mm to 25 mm size range. If required, it can also accommodate steel bars with 20 mm to 50 mm sizes. Cover Blocks are made up of top quality materials which have proven compression strength and water absorption properties. As these cover blocks hold the steel bars efficiently, the concreting can be done on equal height and measures which in turn reduces material used and thus reduces cost at the same time maintains better strength and durability.

Kalliyath TMT is the first to introduce branded binding wire as a high-quality alternative to the rest of the low-quality binding wires. Owing to its superior quality, good packaging, and its availability through an extensive network, Kalliyath Binding Wires got the ISI Certification and thereby became the first branded binding wire in India to get that accolade.

TMT Bar also known as Steel Reinforcement Bar or Thermo Mechanically Treated Bar is the inner strength of construction industry. It protects the structures materials from weather and extreme temperatures. Therefore from the selection of raw materials to the manufacturing process of TMT bars, special care and attention should be given.
SELECTING THE RAW MATERIALS
Selection of raw materials is the most important factor that determines the quality of a TMT bar. At Kalliyath, Steel is produced using high-quality raw materials supplied by world-class suppliers of billets from virgin iron billets like Vizag, SAIL etc. Raw materials for making TMT are also manufactured by Kalliyath to maintain consistency in quality. The raw materials Kalliyath uses have three main advantages.
TMT bars made through this process are then sent to specially arranged labs to test the quality and strength by suing the right chemical composition of F500 grade set by BIS. Also, the sectional weight and strength of each unit of TMT bar is tested every 30 minutes to give customers the best ever.
Kalliyath TMT bars have precise, uniform and parallel rib pattern engraved through computer controlled notch making machines, which results in excellent bond strength with concrete. The right combination of chemicals in Kalliyath TMT bars ensure easier and faster welding without pre-heating. This means stronger and safer weld joints and reduction in wastage during welding at the site. Kalliyath TMT bars are proven to have a higher resistance to cyclic loading conditions and are recommended in earthquake prone areas due to their superior seismic resistant properties. Due to the highly controlled process that ensures a microstructure with a soft core, Kalliyath TMT bars have excellent bendability, making work easier and faster at construction sites.
TMT bars that comes out after the Quenching Process will be of 2500C. These bars are cut into desired sizes and then passed through Automated High-Speed Cooling Bed. This stage involves normal cooling to room temperature where the Austenitic core is transformed to a ductile ferrite + pearlite structure. This finished bar has a microstructure comprising of a tough outer layer of tempered Martensite and a ductile core of ferrite + pearlite. This composite structure gives excellent yield strength to the bar along with superior ductility and weldability. The mechanism of automated cooling bed assures that the bars are uniformly positioned over the toothed racks. The advanced technology helps prevent the damages caused by the collision of TMT bars and thereby gives a unique uniform strength and shape. But in Manually operated rolling mills, labours do this with a hook. The increased strength and toughness of TMT bars create problem during subsequent manual bending operation. It will affect the shape and strength of the TMT bars.
With the help of computerized process, qualified engineers of Kalliyath passes the 1, 2000C billets to the special automated high-speed rolling mill. The process is controlled by monitoring devices, in an all mechanized technical operational environment. This enables the production of rebars with perfect shape, uniform thickness and equal standard length. The rolling mill operating in tandem with the continuous casting machine cools the billet temperature to help reduce the material and within 40 seconds, these billets are made into TMT bars ensuring excellent dimensional tolerance and surface finish.
Most of the rolling mills in Kerala have the manual process which takes too much time and lacks the temperature required for processing. This leads to the loss of quality of the TMT bar.
The process utilize residual heat from the rolling process to attain the desired mechanical properties. Billets, which are heated in the re-heating furnace, are rolled through a series of rolling stands and progressively reduced to the final desired size and shape. The most important factor in this stage is that the temperature of billet should be 1, 2000C.
NECESSARY STAGESFor reduction, billets are passed through the vast automated high-speed rolling mill units of Kalliyath. Normally, TMT bars needed for gauge are passed only 15 to 19 times. But at Kalliyath, bars are passed 21 to 25 times to ensure uniform size, shape and strength to decrease the production time. Mills that work with manual technology reduce the number of passes which results in the loss of quality, strength and unique shape of the TMT bars.
TMT rebars are integral to every construction project. During construction, TMT rebars and concrete complement each other in a way that Reinforced Cement Concrete (RCC) structure can be moulded into any desired shape, with the rebars providing the requisite tensile strength to withstand the load. The practice of cutting and bending them at the site to meet individual requirements can be labor intensive and time-consuming, resulting in enormous material wastage.
Recognizing the need for a customized solution, Kalliyath introduced Steel Fab- ready-to-use cut and bend rebars, a totally new generation product for the first time in India with advanced technology which was totally unheard in the industry. Almost every structure comes with its own unique requirements of design while Kalliyath Steel Fab is manufactured according to the standard specifications.
At its cut and bend mill, that employs the latest Italian technology, rebars are customized to lengths and bends at required angles, in order to meet the project requirements. This fast and efficient service is capable of managing inventories better by reducing material wastage and production costs, apart from ensuring aesthetically superior clean and strong bars, which are made available right at the site. Steel Fab became a total and effective remedy to the entire obstacle in the industry like shortage of manual bar-benders, raw material theft from worksites, shortage of workspace, especially in public infrastructure projects and brought about a drastic revolution.
Following are the features of Kalliyath Steel FAB.
