Round Corner Square (RCS) bars are hot rolled stainless steel sections with a square profile and rounded corners. The rounded-corner geometry helps reduce sharp edges and stress concentration during secondary processing, making RCS bars suitable for machining, forging, fabrication, and other industrial applications.
Maruti Inox manufactures and supplies rolled RCS bars from stainless steel billets and offers them in as-rolled, spot-ground, and straightened conditions. Our RCS bars are available in sizes from 40 mm to 100 mm, with lengths up to 6.0 metres.
Maruti Inox is a stainless steel RCS bar manufacturer and supplier in Gujarat, India. As rolled, spot-ground and straightened.
Stainless Steel RCS Bars
Stainless steel RCS bars, also known as Round Corner Square bars or Round Cornered Square bars, are commonly used as starting material for components that require further machining, forging, or fabrication.
Unlike a conventional sharp-corner square section, the RCS profile has rounded corners. This geometry provides a practical starting shape for secondary manufacturing operations and is particularly useful where the component is produced through forging or machining.
Maruti Inox supplies rolled RCS bars for engineering and industrial requirements where the combination of stainless steel material and a rounded square profile is required.
What Are RCS Bars?
RCS stands for Round Corner Square.
An RCS bar has a square cross-section with rounded corners. These rounded corners distinguish the product from conventional sharp-corner square bars.
RCS bars are generally supplied as hot rolled sections and are used as semi-finished material for further manufacturing processes. Depending on the application, they can be machined, forged, cut, or processed into finished industrial components.
The rounded corners can also make handling and secondary processing more practical by avoiding the sharp external edges found on a conventional square section.
How RCS Bars Are Manufactured
Maruti Inox produces RCS bars through a hot rolling process using stainless steel billets.
The manufacturing route includes the following major stages:
Stainless Steel Billet
The RCS production process starts with stainless steel billets suitable for hot rolling.
Hot Rolling
The billet is heated and passed through rolling operations to progressively form the required round-corner square profile.
Dimensional Control
The rolled section is processed to achieve the required RCS size according to the product specification.
Surface and Straightening Condition
Depending on the requirement, RCS bars can be supplied in as-rolled, spot-ground, and straightened conditions.
This manufacturing process produces a practical semi-finished stainless steel section for subsequent machining, forging and fabrication operations.
RCS Bars for Forging Applications
RCS bars are widely used as starting material in forging operations because their cross-sectional geometry provides a useful material form for producing forged components.
Forging manufacturers can process RCS bars through subsequent heating, forming, cutting and machining operations according to the requirements of the finished component.
The appropriate stainless steel grade and RCS size should be selected according to the forging process, component dimensions, mechanical requirements, and service environment.
RCS Bars for Industrial Applications
RCS bars can be used in a range of engineering and industrial manufacturing applications where a stainless steel round-corner square section is required.
Typical applications include:
- Forged components
- Machined components
- Engineering components
- Industrial machinery parts
- Fabricated components
- Automotive components
- Manufacturing equipment
- Heavy engineering applications
- Components requiring further machining
- Components requiring further forging
The final stainless steel grade should be selected according to the component's operating environment and manufacturing requirements

How to Select the Right RCS Bar
Before ordering stainless steel RCS bars, consider the following factors:
RCS Size
Select the section size according to the final component dimensions and required machining or forging allowance.
Stainless Steel Grade
The grade should be selected based on corrosion resistance, mechanical requirements, temperature, fabrication requirements and the final operating environment.
Supply Condition
Choose between as-rolled, spot-ground and straightened conditions according to the downstream manufacturing process.
Length
Specify the required bar length based on cutting, handling and production requirements.
Quantity
For regular manufacturing requirements, provide the required quantity along with the size and grade so that the appropriate supply can be evaluated.
Application
Specify whether the RCS bar will be used for forging, machining, fabrication or another industrial application. This helps determine the appropriate material specification.
