We are a leading manufacturer and global exporter of premium-quality Circles and Rings, delivering precision-engineered products to industries across Europe, Russia, Saudi Arabia, Oman, Qatar, and the USA. Backed by advanced manufacturing technology and decades of metallurgical expertise, our company serves diverse sectors including flanges, pressure vessels, pipe fittings, automotive, and engineering components. Our commitment to high quality, on-time delivery, and custom solutions has helped us establish a strong global reputation as a reliable partner for clients seeking durable and dimensionally accurate circular components.
Our Circles and Rings are manufactured in a wide range of diameters, thicknesses, and profiles — from as small as 50mm OD up to 2000mm OD with thicknesses ranging from 3mm to 150mm or more, depending on the application. We offer both forged and cut rings, blanks, and rolled circles, available in seamless or welded formats. The products are produced in accordance with international standards such as ASTM, ASME, DIN, EN, and ISO. Each piece is subject to rigorous inspection for dimensional accuracy, concentricity, straightness, surface finish, and mechanical strength. Machined rings with turned surfaces, chamfers, or custom bore profiles can also be supplied as per customer drawings or specifications.
We manufacture Circles and Rings using a variety of high-performance materials including Stainless Steel (SS304, SS316, SS321, SS347, SS410), Carbon Steel (ASTM A105, A36), Alloy Steel (ASTM A182 F11/F22/F91), Duplex & Super Duplex (UNS S31803, S32750), and Nickel Alloys (Inconel 625/825, Monel 400, Hastelloy C276) among others. All materials are sourced from certified mills and comply with ASTM, EN, and DIN chemical and mechanical standards. Each batch undergoes chemical analysis, ultrasonic testing, hardness testing, and where required, third-party inspection. We supply full Mill Test Certificates (MTC) as per EN 10204 3.1 / 3.2 and guarantee traceability and documentation for every ring or circle we export.
To ensure product integrity during transportation, we provide robust packaging options such as wooden boxes, bubble wrap, anti-rust coatings, and edge protectors. Custom marking and labeling are provided as per client or international shipping requirements. Our logistics team ensures safe and timely delivery through both sea and air routes, with full export documentation including MTCs, Certificates of Origin, Packing Lists, and Inspection Reports. With strong exports to Europe, Russia, Saudi Arabia, Oman, Qatar, and the USA, we are well-versed in meeting international compliance norms and customer-specific quality standards. Our commitment to excellence, competitive pricing, and reliable service makes us your ideal partner for Circles and Rings worldwide.
