Oval, Square & Rectangular Pipes Suppliers

We are an ISO 9001:2015 certified manufacturer and exporter specializing in high-quality Oval, Square, and Rectangular Pipes, engineered to meet the rigorous demands of modern industries. These pipes are fabricated from premium raw materials including carbon steel, stainless steel (grades 304, 316), and alloy steel, ensuring excellent mechanical strength, corrosion resistance, and durability. Our products adhere to internationally recognized standards such as ASTM A500, EN 10219, IS 4923, and DIN, guaranteeing compliance with both dimensional and chemical specifications required by global customers.

The manufacturing process of oval, square, and rectangular pipes involves cold forming and electric resistance welding (ERW) or high-frequency welding (HFW) of flat steel strips or coils. The steel strip is first roll-formed into the desired shape and then welded longitudinally to form a seamless-looking hollow section. Post-welding treatments such as heat treatment, straightening, sizing, and surface finishing ensure uniform wall thickness, dimensional accuracy, and enhanced mechanical properties. Pipes are available in a wide range of dimensions, with outer sizes typically from 20mm up to 600mm in width or diameter, and wall thicknesses ranging from 1.5mm to 20mm or more, based on customer requirements.

Our Oval, Square, and Rectangular Pipes come in various grades including ASTM A500 Grade B and C, ASTM A513, and EN 10305, offering exceptional tensile strength, yield strength, and elongation. Chemical compositions are strictly controlled, with carbon content typically between 0.15% to 0.25%, manganese ranging from 0.5% to 1.2%, and trace amounts of phosphorus and sulfur kept minimal for improved weldability and toughness. These pipes are tested for mechanical properties such as tensile strength, yield strength, impact resistance, and hardness, in addition to non-destructive testing (NDT) methods like ultrasonic and radiographic inspection to ensure structural integrity.

The versatility of oval, square, and rectangular pipes makes them ideal for a broad range of applications including structural frameworks, construction scaffolding, automotive chassis, agricultural machinery, furniture manufacturing, fencing, and architectural projects. Their flat surfaces allow easier joining and welding compared to circular pipes, making them favored in fabrication where precision and aesthetics are important. Oval pipes, with their unique streamlined shape, are often used in automotive exhaust systems and decorative structures where aerodynamic or design considerations are key. We export our pipes to major international markets such as Europe, Russia, Saudi Arabia, Oman, Qatar, and the USA, maintaining strict quality control and international shipping standards. Packaging solutions include steel bundling, wooden crates, plastic wrapping, and end caps to protect against corrosion and physical damage during transit. Each shipment is accompanied by a comprehensive Mill Test Certificate (MTC) detailing chemical analysis, mechanical testing results, and compliance with relevant standards, ensuring complete traceability and customer satisfaction.
