Welcome to Maduka Metals, your trusted partner for premium industrial materials right here in Abuja. We take pride in supplying and manufacturing high-grade Duplex Steel Bars and Rods, engineered to meet the rigorous demands of Nigeria’s growing industrial sector. Our commitment is to provide robust, reliable solutions that empower your most ambitious projects, ensuring durability and performance where it matters most.
Duplex Steel is a remarkable material, expertly blending austenitic and ferritic stainless steels. This unique composition gives it an excellent strength-to-weight ratio and outstanding resistance to corrosion and stress cracking. Essentially, you get the best of both worlds: the toughness of ferritic grades and the ductility of austenitic ones, resulting in a product that is both incredibly strong and highly resilient in challenging conditions.

Yes, Duplex Steel Bars offer excellent corrosion resistance, particularly against stress corrosion cracking, pitting, and crevice corrosion. Their dual-phase microstructure enhances their resistance in harsh environments.
Duplex steel bars perform well in high-temperature environments due to their excellent strength and resistance to oxidation and scaling. Their dual-phase microstructure enhances thermal stability and durability under heat stress.
Yes, duplex steel rods can be customized in size and length to meet specific application requirements. They can be tailored to various dimensions and tolerances for different industries.
You’ll find our Duplex Steel Bars and Rods hard at work in some of the most demanding environments. They are essential in the construction of chemical processing plants, offshore oil and gas platforms, and desalination units. They are also perfect for structural components in bridges, architectural designs in coastal areas, and critical parts within the pulp and paper industry, offering long-lasting performance where ordinary steel would quickly succumb to corrosion and wear.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
