Based in Kolkata, India, Neil Metals is a well-known producer and supplier of stainless steel flat bars, distinguished by their unrivalled quality, longevity, and precision engineering. The business provides flat bars in a range of stainless steel grades that satisfy global requirements for industrial, fabrication, and building applications. Neil Metals guarantees that every flat bar offers exceptional strength, resistance to corrosion, and dimensional accuracy through its cutting-edge facilities and stringent quality control procedures. In India and around the world, Neil Metals, which serves the infrastructure, marine, automotive, and general engineering sectors, has established a strong reputation for prompt delivery, dependable service, and customer-focused solutions.
Iron, chromium (16–18%), nickel (8–10.5%), and trace amounts of carbon, manganese, and silicon make up the majority of stainless steel flat bars, which are commonly offered in grades 304, 316, 410, and 430. Depending on the grade, these bars have outstanding tensile strength (500–750 MPa), yield strength (200–450 MPa), and elongation of 40–50%. Particularly in austenitic grades, they show good formability, weldability, and corrosion resistance. Because martensitic grades, such as 410, have greater hardness and resistance to wear, stainless steel flat bars are perfect for both structural and ornamental applications in a variety of settings.

Because of their strength, adaptability, and corrosion resistance, stainless steel flat bars are widely used in the automotive, railroad, marine, and construction industries. They are used as structural supports, brackets, and reinforcements in construction. They are utilised for fixtures, ladders, and deck structures in the maritime industry. They are used in engine parts, mounting brackets, and chassis frames in the automotive industry. In order to manufacture gates, grills, base plates, and machine parts, they are also essential in fabrication, architecture, and general engineering. Stainless steel flat bars are a preferred material in a variety of industries due to their versatility in both structural and aesthetic applications.
Stainless steel flat bars can be cut using methods like a saw (manual or power), angle grinders, laser cutting, or water jet cutting. The choice of method depends on the bar's thickness, precision required, and available equipment.
Yes, stainless steel flat bars are highly resistant to corrosion due to their chromium content, which forms a protective oxide layer. This layer prevents rust and deterioration, making stainless steel ideal for applications exposed to moisture and harsh environments.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
