Stainless Steel 316/316L Angles and Channels
Rose Metal Industries is a trusted manufacturer, stockist and exporter of high-quality Stainless Steel 316 and 316L Angles and Channels, offering structural and fabrication-grade sections to industries and fabricators. Our SS 316/316L angles and channels are known for their strong corrosion resistance, mechanical strength, and longevity, making them ideal for industrial, architectural and marine applications. We supply to clients across South India — including Tamil Nadu, Andhra Pradesh, Karnataka, Telangana, Puducherry (Pondicherry) and the Andaman & Nicobar Islands — as well as to international customers via export packing and documentation..
The addition of molybdenum in SS 316 and 316L enhances resistance to pitting, crevice corrosion and chloride attack — a major advantage over SS 304, especially in coastal, marine and chemical plant environments. SS 316L, with its lower carbon content, reduces carbide precipitation risks during welding and ensures sustained corrosion resistance in welded structures. Rose Metal Industries offers both hot‑rolled and cold‑finished angles and channels, with clean surfaces, uniform thickness and accurate dimensional tolerances to meet rigorous engineering standards..
Our inventory includes a wide range of angle sizes (equal angles and unequal angles) and channel sizes, suitable for structural frames, equipment supports, ladders, handrails, platforms and architectural elements. The SS 316/316L sections are available in polished or pickled finishes, or mill-finish as per customer requirement. This flexibility makes them a preferred choice for fabricators, EPC contractors, marine equipment manufacturers, architectural firms, chemical plants and food processing units across southern India and overseas..
Rose Metal Industries ensures strict quality control and compliance with global standards. All angles and channels are produced from certified stainless steel billets or coil/plate inputs, with full traceability via mill heat numbers and Mill Test Certificates (MTC). We perform chemical composition verification, mechanical testing, and surface inspection to guarantee product conformity. For export orders, packaging, labeling and documentation are arranged to meet international shipping and customs requirements.

Frequently Asked Questions (FAQ)
Q1: What is the difference between SS 316 and SS 316L angles and channels?
A: SS 316L has a lower carbon content (≤0.03%) compared to SS 316, which minimizes carbide precipitation during welding. This improves corrosion resistance in welded zones, making 316L ideal for fabricated or welded structures, especially in coastal or chemical plant environments.
Q2: Do you provide mill test certificates (MTC) for stainless steel angles and channels?
A: Yes — Rose Metal Industries issues MTCs for all SS 316/316L angles and channels and can facilitate third-party inspection, PMI testing, or chemical analysis on request.
Q3: Which standards do your SS 316/316L angles and channels comply with?
A: Our structural sections conform to ASTM A276 / A484, EN 10088 / EN 10213, and JIS SUS 316 / 316L standards. Custom standards can be accommodated depending on project requirements and regional specifications.
Q4: Can you supply custom sizes, thicknesses, and surface finishes?
A: Yes — we provide custom leg widths, unequal angles, channel dimensions, and thicknesses. Surface finishes such as pickled & passivated, polished (No.4 or Mirror), or mill-finish are available as per client specifications.
Q5: Where do you supply SS 316/316L angles and channels?
A: We supply across southern India — including Tamil Nadu, Andhra Pradesh, Karnataka, Telangana, Puducherry (Pondicherry) and the Andaman & Nicobar Islands. We also export globally with full packaging, documentation, and quality certification.
