Steel reinforcing bars, or rebar, are most typically employed in concrete constructions to give structural and tension support. Rebar typically costs around $0.75 per foot, with minor pricing differences for thinner or thicker sticks. Prices for 2-foot lengths can range from $1.40 to $1.84. Prices for 4-foot lengths range from $3.05 to $3.94. Rebar is used in concrete structures to provide strength and durability. It comes in various sizes and shapes depending on the requirement for the structure. The type and quantity of reinforcement required depends on the purpose of the construction and its use. For example, if the structure is meant for pedestrian traffic, such as a sidewalk or pathway, then fewer large bars is sufficient compared to one big bar for a road bridge. The price of rebar varies based on its size and grade. There are two main grades of rebar: standard and premium. Standard rebar is available in four common sizes: 6-, 9-, 12-, and 15-gauge. Premium rebar is available in five additional sizes: 3-, 4-, 5-, 6-, and 7-gauge. Premium rebar is generally more expensive than standard rebar because it has better quality steel in greater quantities. Rebar prices are also influenced by where it is produced. US production facilities usually have lower overhead costs because they are smaller and less complex.
