We carry Carbon Steel Square Bar in A36, 1018, and 1045.
A36 offers good strength, high durability, heavy weight, easy weldability, and low cost. A36 steel is the most common low-carbon structural steel.
1018 steel is the most commonly available of the cold-rolled steels. It has a good combination of all of the typical traits of steel - strength, some ductility, and comparative ease of welding and machining.
1045 is a commonly used low carbon steel alloy with good strength, ductility, and ease of machining.
