Copper Bar
Stellanox Steel is a reliable supplier of premium-grade Copper Bars, widely used in electrical transmission, busbars, earth systems, switchgear components, and industrial fabrication. We offer copper bars in various profiles including flat bar, round bar, square bar, and hex bar, crafted from high-conductivity grades like C11000 (ETP Copper), C10100 (OFHC Copper), and C12200 (DHP Copper).
Copper bars are known for their superior electrical and thermal conductivity, machinability, and corrosion resistance, making them indispensable in power, electronic, marine, and automotive industries.
What are Copper Bars?
Copper Bars are solid, straight lengths of copper in different shapes, used where maximum conductivity, mechanical strength, and surface finish are essential. These bars serve as the backbone of electrical systems, and are ideal for power distribution units, welding terminals, heavy-duty connectors, and earthing systems.
We provide copper bars in drawn, rolled, or extruded forms and soft to hard tempers, with options for tinning, polishing, and custom machining.
