-63 Products
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.
