A rolled bar is a long, solid cylindrical metal bar manufactured through rolling processes. Known for its strength, durability, and uniform surface finish, it is commonly used for shafting in a wide range of industrial and commercial applications.
Kesari Alloys offers hot rolled bars in carbon steel, alloy steel and stainless steel which are suitable for forging, upsetting, re-rolling and ring rolling. We maintain optimal reduction ratios in rolled bars by selecting the most appropriate ingotsor billet size which results in better soundness. They can be extensively used in machined components, pump shafts, valves, daily equipment, surgical and medical parts, gears, bearings, thread bars etc.
Kesari Alloys is among the steel roll bars manufacturers and an alloy steel rolled bars manufacturer in India. We are a rolled bars for shafting supplier, a square bars manufacturer in India and an alloy steel flat bars supplier, and we also make forged square bars for customers who need forged rather than rolled finish.

Kesari Alloys manufactures carbon steel, alloy steel and stainless steel Rolled Bars which comes in various thickness and dimensions to meet with various industrial usages. Kesari Alloys is popular for finest quality and superior finish of these carbon steel, alloy steel and stainless steel rolled bars. The ultra modern machineries and calibrated testing facilities in Kesari Alloys ensures roll out of highest quality of Hot Rolled Bars.
Kesari Alloys maintain consistent diameter throughout the length of the carbon steel, alloy steel and stainless steel rolled bars resulting in better weight control in cut pieces. The most common length is 6 meters but it can be varied between 3.5 and 12 meters depending on the producing rolling mill. Longer lengths Rolled Bars can significantly reduce material handling and increases productivity. Heat treatments may restrict the maximum length. Kesari Alloys hot rolled black carbon steel, alloy steel and stainless steel bars are excellent for threading, drilling, machining, & sawing. Each and every rolled bar which is manufactured at Kesari Alloys undergoes a rigorous inspection procedure to ensure that our clients get the finest quality.
Kesari Alloys is an alloy steel round bar manufacturer and one of the round bar suppliers in India that ships hot rolled round bars, hot rolled steel bars and hot rolled alloy steel round bars in carbon, alloy and stainless steel. Hot rolled round bar sizes run from 16 mm to 180 mm, so the same page serves buyers searching for alloy steel round bars manufacturers in India, hot rolled round bars manufacturers, hot rolled steel bars manufacturers or a round bar manufacturer in India. As a hot rolled alloy steel bars manufacturer we supply hot rolled round steel bars rolled from our ingots and billets, with the reduction ratio chosen to give sound steel.
Round bar specification follows the grade and the Indian standard (IS) or international standard (EN, SAE, DIN, AISI) you name on the order, so a round bar Indian standard enquiry is handled the same way as an EN or SAE one. Hot rolled round bar grades include EN8, EN9, EN19, EN24, EN31, 42CrMo4, 4140, 4340, 8620 and C45; see the steel grade family for the full list, each with its own composition page. Bars are supplied as hot rolled (black), are 100 % ultrasonically tested to ASTM standard, and are marked with heat number, grade and size. Hot rolled round bar tolerances follow the standard agreed on the order.
The round bar sizes chart above gives the range: standard round bar sizes from 16 mm to 180 mm (round bar sizes in mm, or steel round bar sizes in mm for short), square bars from 20 mm to 90 mm and flat bars from 25 to 250 mm width and 6 to 40 mm thickness. Use this as a metal round bar sizes and steel round bar dimensions guide: a mild steel round bar size chart, a stainless steel round bar size chart and an alloy round bar size chart share the same sizes, because the bars are rolled to size and not to grade. The theoretical weight per metre of a round bar is diameter squared x 0.00617 kg (diameter in mm); of a square bar, side squared x 0.00785 kg.

Theoretical weights for steel of density 7.85 g/cm³. Round bar sizes in inches can be converted from the mm sizes above.
Steel square bars are rolled in 20 to 90 mm sections; the steel square bar standard sizes follow the table above, and square bar specification and square bar sizes are fixed by grade and tolerance on the order. We also make a forged square bar for customers who need a forged finish instead of a rolled one. Alloy steel flat bars and steel flat bars are rolled up to 250 mm wide and 40 mm thick; a steel flat bar chart, steel flat bars sizes and hot rolled steel flat bar sizes can be read from the sizes above, and the carbon steel flat bar specification and steel flat bar specification depend on grade.
Among stainless steel square bar manufacturers in India and stainless steel flat bar manufacturers in India, Kesari Alloys is also a steel flat bar manufacturer and one of the stainless steel square bar suppliers: stainless steel round bars, stainless steel flat bar and stainless steel square bar are available in the stainless grades SS410, SS430 and SS409. Steel flat bar uses include machine parts, base plates and fabrication; stainless steel flat bar uses include equipment and corrosion-resistant parts; round bar uses and square bar uses range from shafts to tooling.
Hot rolled steel bar price, round bar price and steel square bar price depend on grade, diameter or section, length, heat treatment and quantity. We do not publish a round bar price list or a steel square bar price list in India because alloy steel moves with raw material costs; the hot rolled alloy steel round bars price for EN24 is not the same as the price for EN8. Stainless steel round bar prices and mild steel flat bar prices are also quoted per order. For a round bar price 10mm enquiry, note that our round bars start at 16 mm.
Send grade, size, quantity and location through the contact page. Square bar price, round bar price and hot rolled steel bar sizes with delivery time are confirmed in the quotation. We act as a round bar manufacturer and as round bar suppliers for stockists, forging shops and machine shops.
Rolled bars are the usual feed for ring rolling steel: the bar is cut, upset and pierced, and the ring rolling process then expands it to size. Our rolled bars suit ring rolling steel and ring rolling stainless steel, as well as forging, upsetting and re-rolling. Axle steel bars are supplied in EN8, EN9 and other medium carbon grades; shafts, pump shafts and gear blanks use the same bars. Rolled bars steel from Kesari Alloys is also available straightened.
Rolled bars are long solid steel bars made by hot rolling ingots or billets. They are used for shafts, gears, pump parts, forgings and machined components.
Hot rolled round bars from 16 mm to 180 mm, square bars from 20 mm to 90 mm and flat bars 25 to 250 mm wide and 6 to 40 mm thick.
