Stainless Steel 347 Angles Angles and Channels
Rose Metal Industries is a leading manufacturer, stockist and global exporter of Stainless Steel 347 Angles and Channels, supplying premium structural profiles for high-temperature, corrosive and heavy-load applications. SS 347 is a niobium-stabilized austenitic stainless steel grade known for its resistance to intergranular corrosion during welding and elevated temperature service. Our 347 Angles (Equal & Unequal) and Channels (C, U & J type) are widely supplied across Tamilnadu, Andhra Pradesh, Karnataka, Telangana, Puducherry (Pondicherry), and the Andaman & Nicobar Islands, ensuring reliable support for construction, fabrication and industrial engineering projects...
Stainless Steel 347 Angles and Channels manufactured by Rose Metal Industries conform to international standards such as ASTM A276, ASTM A479, ASME SA276 and EN 10088. These high-grade profiles are widely used in structures exposed to continuous temperatures up to 870°C. The addition of niobium prevents carbide precipitation and enhances resistance to scaling and oxidation, making these profiles ideal for demanding environments such as boiler support frames, furnace structures, heat exchangers, marine engineering and refinery equipment..
Industrial hubs such as Chennai, Bengaluru, Hyderabad, Coimbatore, Visakhapatnam, Mysuru, Vijayawada, Puducherry and Port Blair heavily depend on structural components that can withstand aggressive coastal climates and high mechanical loads. SS 347 Angles and Channels supplied by Rose Metal Industries offer superior tensile strength, excellent weldability and long-lasting corrosion resistance, making them suitable for offshore platforms, chemical plants, thermal power stations, conveyor systems and architectural frameworks in both inland and coastal regions.
We maintain a comprehensive inventory of Equal Angles, Unequal Angles, C-Channels, U-Channels, J-Channels and Custom Fabricated Profiles in SS 347 and 347H. All sections are available in hot-rolled, cold-drawn, and polished finishes, with thickness options ranging from 3 mm to 20 mm and lengths up to 6 meters or customized on request. Our manufacturing capabilities include laser cutting, bending, drilling and fabrication, allowing clients to receive fully customized structural components for heavy-duty applications in South India and global markets..
