Welcome to Maduka Metals, your trusted partner for premium stainless steel right here in Abuja. We specialize in supplying high-performance materials built to withstand the toughest conditions, and our Stainless Steel 310 Hollow Bar is a perfect example. This grade is engineered for resilience, offering exceptional strength and resistance to oxidation, making it an ideal choice for demanding industrial and construction projects across Nigeria. We pride ourselves on delivering not just quality products, but also the reliable service and expert support our local clients deserve.
The strength of Stainless Steel 310 comes from its carefully balanced composition, rich in both chromium and nickel. This specific blend gives the hollow bar its signature ability to maintain integrity under intense heat, resisting scaling even when temperatures soar. Mechanically, it’s a real workhorse, boasting impressive tensile strength and good ductility. This means it can handle significant stress and pressure without failing, which is precisely why it’s selected for situations where both high temperature and structural load are major concerns.

The high chromium (25-30%) and nickel (20-22%) content in SS 310 enhances its corrosion resistance by forming a protective oxide layer on the surface, which shields the material from aggressive chemicals, oxidation, and high-temperature corrosion in harsh environments.
SS 310 Hollow Bars are commonly used in industries such as petrochemical, chemical processing, power generation, and food processing. These bars are essential for components exposed to high temperatures, corrosion, and extreme conditions, including furnace parts and heat exchangers.
You’ll find the Stainless Steel 310 Hollow Bar hard at work in some of the most critical applications. It’s a go-to material for constructing industrial furnace parts, heat treatment fixtures, and vital components within refinery and chemical processing equipment. Its hollow design is particularly useful for fluid transfer systems or as a lightweight yet incredibly strong structural member in high-temperature environments. From supporting major industrial operations to enabling innovative architectural designs, this versatile bar provides the durable, heat-resistant backbone that demanding projects require to succeed long-term.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
