TMT (Thermo Mechanically Treated) bars or Re‐bars (Reinforcement bars) are high strength steel bars with a circular cross section and transverse ribs on the outer surface. The major application of TMT bars is in Reinforced Concrete Cement (RCC) work to provide structural support to buildings, bridges, flyovers, dams etc. TMT bars are available in the market in sizes ranging from 8mm‐ 80mm in Diameter. The most common ones are 8mm, 10mm, 12mm, 16mm, 20mm, 25mm, 28mm, and 32mm and are readily available at OfBusiness.com Special Properties of TMT Bars TMT bars are processed and treated accordingly to be made suitable for use with RCC in construction. ● Strength and Ductility ‐ TMT bars are highly ductile in the core thus resisting failure on even 180 degrees of bending. The bars are thermally heated and quenched to increase the tensile strength to withstand large stresses that any structure may undergo. ● Chemical Bonding with Concrete Cement ‐ TMT bars are chemically and thermally treated to bond well with the concrete cement mixture used in construction. ● Thermal Properties ‐ TMT and Concrete cement have similar coefficients of thermal expansion this using them together ensures that no stress concentration voids will be formed inside the structure that might lead to failure. Different grades of TMT bars available TMT bars come in different grades, each with specific properties and applications. The different grades available in the market are Fe 450 (construction of domestic building), Fe 500 (Construction of high rise buildings corporate towers), Fe 500D (Construction of high rise buildings in earthquake prone areas), Fe 600 (Construction of large structures such as bridge, dam, and flyovers) each of them have different tensile strengths, ductility and have specific applications accordingly.

Steel plates and sheets are manufactured and sold under two major names HR (Hot Rolled) and CR (Cold Rolled) based on the temperature at which rolling takes place. Both HR and CR sheets have different physical properties and thus are suitable for different applications. CR sheetsplates CR sheets are basically hot rolled products with enhanced physical properties of steel, such as dent resistance, high strength, tensile strength, and welding properties. All cold products provide a superior surface finish, and are superior in tolerance, concentrically, and straightness when compared to hot rolled. CR steel platessheets are expensive. Features of CR sheetsplates � High grade steel � Corrosion resistant � Uniform thickness � High strength Applications: � Tube making, furniture, electrical panels, household appliances etc., � Automobile industry to make car body panels HR sheetsplates HR sheets are soft enough to bend in any direction, without cracking. They are ductile enough for shallow drawing used in variety of industries in the domestic market. Features of HR sheetsplates: � Rust ­free surface � Clean surface finish Applications: � Manufacturing pipes, tanks, bicycle frames, ships, LPG cylinders and shuttering plates etc., � Highly used in construction industry GIGPGC sheets These are galvanized steel sheets or coils that are zinc coated. GI sheets are available in GI coils, Galvanized Plain sheets, and Galvanized Corrugated Sheet (GC). Applications: � Automotive applications, air ­conditioners, refrigerators, microwaves, and vending machines etc. (GI Sheets) � Steel structure and Industrial sheds, warehousing buildings, houses etc. (GC Sheets)

OfBusiness’ steel coil range helps you select products that suit your requirement. The steel coils sold on OfBusiness.com have excellent strength, ductility, weldability, and bendability. You can find Hot Rolled coils between 2 ­- 7 mm thick and Cold Rolled coils between 0.15 ­- 3 mm. Read more about the differences, applications and features of CR and HR coils. HR Coils Hot rolled coils are more malleable and perfect for industrial applications. Generally, hot rolled has a blue­ grey appearance and a rough feel once it completes the rolling process. Hot rolled coil is broadly known for its exceptional quality and consistency. Features of HR Coils ● High tensile strength ● Abrasion resistance ● Durability ● Excellent finish ● Lower cost as it is often manufactured without any delays in the process, and therefore the reheating of the steel is not required. Where Should You Use HR Coils? ● Pipes ● Tanks ● Railway cars ● Bicycle frames ● Ships ● Engineering and military equipment ● Automobile and truck wheels frames and body parts ● Feedstock for cold rolling mills ● Feedstock for higher value­added steel products ● Process industry ● Marine environments ● High­end construction CR Coils Cold rolled coil has higher strength and hardness, but it’s not that ductile. It is suitable for outer parts of automobiles which require anti­dent properties. Unlike HR coils, CR coil is rolled to its final dimensions below scaling temperatures. Features of CR Coils ● Greater degree of ductility ● High tensile strength ● Excellent dent resistance quality ● Good magnetic properties ● Welding properties Where Should You Use CR Coils? ● Precision tubes ● Steel containers ● Bicycle frames ● Furniture ● Automobile and truck wheels frames and body parts

Steel beams are critical to the support of a building, spreading the load of the building laterally to ensure that it is evenly distributed. Classification of beams is basically based on supports, geometry, the shape of the cross section, and its material, of which shape is the most important. The shape of a beam affects its strength, weight, and ultimate cost. Types of beams ● I‐Beam: These steel beams are shaped like a capital letter “I”. They have tapered flanges and are commonly used in industrial applications. I‐beams may be used both as beams and as columns. They are used for commercial and residential construction, lifts, mezzanines, platforms etc. ● T‐Beam: These have a T‐shaped cross‐section. They are used in commercial and residential construction, bridges etc. ● Channels: These have a c‐shaped cross‐section, like one‐half of the I‐beam. They are generally used in tractor trailers, light construction segment etc. ● H‐Beam: These are generally longer and heavier than I‐beams, with longer flanges. H‐ Beams are used as construction support beams for commercial and residential construction, mezzanines and platforms, bridges, trailer and truck bed framing etc. OfBusiness.com also helps you acquire powder coated and galvanized beams. Coating extends the life of steel beams, steel plates, and piping or other structures.
