Carbon steel flat bars combine the strength of solid structural steel with the formability and adaptability of mild steel. Common grades such as 1018 and A36 flat bars are easy to work with, making them ideal for various construction and fabrication projects.

Round Bars

Round bars are available in various diameters and weights, and are widely used in building work, fabrication, and even precision machining and decoration. Round bars ensure superior surface finish and accurate dimensions, making them essential for architectural frameworks, supports, shafts, beams, and pivots.As a practical alternative to standard black mild steel, carbon steel rods, carbon steel round bars, and cold rolled round bars provide reliable performance for a variety of projects.

Square Bars

Square bars are often preferred for general repairs of plant equipment, railings, and more in commercial settings. Their shape, diameter, and lightweight nature make them highly suitable for both commercial and residential projects. Square bars deliver exceptional results in a highly desired format.

Hot Rolled Oval and Half-Round Bars

Steel and metal oval or half-round bars are another option for architectural applications requiring a certain aesthetic. Joining to flat surfaces, hot rolled oval and half-round bars are often used for trim and molding in construction, especially in homes and office buildings.

Chatham Steel offers a wide range of steel flat/rectangular bars for a wide variety of applications, including carbon steel flat bars, strips, universal mill plates, and more.
