Black Bar

Black Bars are widely utilized in automotive, construction, and engineering industries due to their high strength and durability. These bars are manufactured with advanced hot rolling techniques, providing a tough surface and structural integrity. They are ideal for applications where surface finish is not a critical factor but strength and reliability are. Available in multiple grades and sizes, Black Bars ensure long-lasting performance in demanding environments.

Black Bars are offered in various material grades including stainless steel, duplex steel, nickel alloys, and copper-nickel alloys. From ASTM A276 stainless steel to Inconel and Monel alloys, these bars meet the diverse requirements of global industries. Customers can choose from round, square, hex, and rectangular forms, available with hot rolled, polished, or machined finishes, depending on their application needs.

Each Black Bar undergoes strict quality control and is processed through cutting, punching, slotting, drilling, and machining as per customer specifications. With tolerance standards like DIN 671 and ASTM A484, these bars are crafted to maintain dimensional accuracy. They are available in diameters from 1mm to 450mm and lengths from 1 to 6 meters, or customized upon request, ensuring suitability for varied industrial uses.

Black Bars are exported to several countries including Saudi Arabia, UAE, Malaysia, Qatar, USA, and South Africa. Known for corrosion resistance and mechanical strength, these bars are packed and delivered following international export standards. With certifications such as NACE MR0175/ISO 15156, they are trusted by industries across oil & gas, petrochemical, marine, and energy sectors.

Black Bars are engineered to handle high-stress environments where mechanical strength is crucial. These bars are typically unpolished and retain a dark surface from the manufacturing process, offering excellent weldability and load-bearing capability. Their resilience makes them ideal for heavy-duty frameworks, support structures, and base plates in industrial and infrastructure projects.
