With state-of-the-art manufacturing techniques and customer focus, Rupal Metals is relied upon by customers across the country for consistent quality, timely delivery, and competitive pricing. We take pride in fostering industrial growth through versatile high-grade stainless steel hollow bars.
Rupal Metals’ Stainless Steel Hollow Bars are mainly iron, chromium (usually 10.5%-30%), nickel, and small amounts of manganese, carbon, and molybdenum. Chromium improves corrosion resistance through the development of a passive oxide film, while nickel enhances toughness and ductility. Mechanical properties consist of high tensile strength, yield strength, and hardness, providing durability against stress. The hollow bars show high resistance to wear, oxidation, and chemical damage, with good weldability and machinability. These properties render them suitable for demanding environments with long-term and reliable structural components.

Stainless steel hollow bars offer excellent strength, corrosion resistance, and durability, making them ideal for demanding industrial applications. They are lightweight yet strong, resistant to rust, and perform well in harsh environments like chemicals, high temperatures, and marine conditions. Their versatility suits industries like automotive, aerospace, and construction.
Industries such as automotive, aerospace, construction, and oil & gas benefit greatly from stainless steel hollow bars due to their strength, corrosion resistance, and versatility. These bars are ideal for structural components, hydraulic systems, shafts, and piping, providing reliability in demanding environments like high pressure, extreme temperatures, and exposure to chemicals.
Stainless steel hollow bars are manufactured through processes like extrusion, piercing, or rotary piercing, followed by elongation to form hollow tubes. These bars undergo heat treatment for strength and durability, followed by machining to achieve precise dimensions. The process ensures high-quality, corrosion-resistant, and versatile hollow bars for industrial applications.
Rupal Metals Stainless Steel Hollow Bars are extensively used by industries such as automotive, aerospace, oil and gas, construction, and machinery industries. Their mechanical strength and corrosion resistance properties make them suitable for production of shafts, hydraulic cylinders, rollers, and structural components exposed to heavy load and harsh conditions. They are generally used in chemical processing facilities, marine engineering applications, and food processing machineries where hygiene and durability are a major concern. Moreover, hollow bars cater to tailored engineering applications demanding accuracy, high strength-to-weight ratio, and wear and corrosion resistance to guarantee long service life and minimal maintenance.






We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
