Stainless Steel 304/304L Sheets,Plates and Coils
Rose Metal Industries is a reputed manufacturer, stockist and exporter of high-quality Stainless Steel 304 / 304L sheets, plates and coils serving domestic markets in India (including Tamilnadu, Andhra Pradesh, Karnataka, Telangana, Puducherry (Pondicherry) and the Andaman & Nicobar Islands) as well as global customers. Our product range includes hot-rolled and cold-rolled finish options, mirror finishes, BA (bright annealed) coils and precision-graded plates tailored for diverse industries. We combine modern rolling & finishing facilities with rigorous quality control to ensure consistent corrosion resistance, formability and long-term performance for both industrial and architectural applications.
SS 304 and SS 304L are austenitic stainless steels known for an excellent balance of formability, weldability and corrosion resistance. Rose Metal Industries supplies these grades as sheets (thin gauge, trimmed edges), plates (thicker structural plates) and coils (wide width, long length) in various finishes and temper conditions. Our 304/304L stock is produced to recognized international standards and is suitable for fabrication techniques such as stamping, bending, deep drawing and welding — making them ideal for food processing equipment, kitchen appliances, architectural facades, chemical & petrochemical equipment and many engineered components.
To support OEMs and distributors across South India and export markets, we offer Kitting, cut-to-size, edging and surface treatment services. For island and coastal territories such as the Andaman & Nicobar Islands and coastal Tamilnadu, our packaging and finishing practices are optimised to prevent transit damage and preserve surface integrity. Our export documentation, mill test certificates (MTC), and traceability systems ensure compliance with international buyers in the Middle East, Europe, Africa and Asia Pacific markets..
Quality assurance at Rose Metal Industries includes dimensional checks, surface inspection, mechanical testing and chemical verification. We supply mill certificates and test reports on request. Typical customers include fabrication shops in Hyderabad and Bengaluru, construction and façade contractors in Chennai and Tamilnadu, and OEM suppliers in Andhra Pradesh and Karnataka — all relying on our consistent lead times, broad stock depth and ability to supply large coil orders for continuous processing lines.

Frequently Asked Questions (FAQ)
Q1: What is the difference between 304 and 304L?
A: 304L contains a lower maximum carbon content (≤0.03%), which minimizes the risk of carbide precipitation during welding. This makes 304L more suitable for heavy-welded components where post-weld annealing is not performed. Mechanical properties of both grades remain largely comparable.
Q2: Do you provide Mill Test Certificates (MTC) and test reports?
A: Yes — Rose Metal Industries provides MTCs with every supply lot and can arrange third-party inspection, PMI testing, chemical analysis and additional documentation required for domestic and export projects.
Q3: Can you supply cut-to-length sheets, slit coils and precision plates to Tamilnadu and island territories?
A: Yes — we deliver cut-to-length sheets, slit coils, leveled strips and precision-cut plates across Tamilnadu, Andhra Pradesh, Karnataka, Telangana, Puducherry and the Andaman & Nicobar Islands. Customized export packing and documentation can be arranged on request.
Q4: Which standards do your sheets, plates and coils follow?
A: Our Stainless Steel 304/304L sheets, plates and coils comply with major international standards including ASTM A240, ASTM A480, ASME SA240 and EN 10088. We can also supply materials according to client-specific standards and tighter tolerances.
Q5: How should I choose between sheet, plate and coil?
A: Select coils for continuous processing, roll forming and slitting operations; sheets for flat fabrication, stamping and general manufacturing; and plates where greater thickness, strength or load-bearing capacity is required. Our technical experts can guide you in choosing the appropriate form for your application.
