Show full description

Carbon Steel Cold Finished 1018 Rectangle Bar

Our 1018 cold-finished carbon steel rectangle bar offers excellent dimensional accuracy and a smooth, bright surface finish. These flat bars are frequently used for manufacturing mounting plates, machinery bases, and general-purpose brackets. The cold-finishing process increases the material's yield and tensile strength compared to hot-rolled alternatives. 1018 steel is highly valued for its exceptional weldability and ease of machining in both manual and CNC operations. Onlinemetals.com provides 1018 cold-finished bars in a wide range of dimensions to support your versatile fabrication needs.
