How much does reinforced steel cost?

Rebar cost by grade or size

To decide on your total rebar cost, the amount you’ll usually pay is based on the length and diameter — which can range from $0.18 to as high as $6.20 per linear foot. For most residential applications, your contractor will use #3, #4, or #5 rebar in grades 40 or 60. The grade refers to the strength of the rebar or how many pounds per square inch it can handle. Most rebar manufacturers measure the grade based on the KSI or the kilopound per square inch. 

This critical part of the construction is designed to support structures and weight. The grade ratings look at both the yield and tensile of the rebar. The yield strength is measured when the rebar starts to change shape, while the tensile strength is determined when the rebar breaks or fails

Let’s take a closer look at the various options and prices available for most residential projects.

Rebar #3

Rebar #3 is the smallest size available and is just 3/8 inches in diameter. This rebar costs between $0.18 to $1.25 per linear foot — common in lighter, non-load-bearing applications like a walkway, patio, or driveway. This rebar is also called grade 40 and 60 size #3.

Rebar #4

This rebar is ½-inch in diameter and is commonly used for foundation floors, walls, and larger driveways. Rebar #4 comes in grades 40 and 60 and costs between $0.30 and $2.00 per linear foot.

Rebar #5

Rebar #5 is also available in grades 40 or 60 — usually the largest size compatible with residential construction. This rebar is 5/8 inches in diameter and works well with foundation beams, footings, and standard foundations. It costs between $0.45 and $2.55 per linear foot.

Rebar #6 and larger

Rebar #6 and anything larger than this size isn’t ideal for residential construction. This option is a much heavier gauge steel bar most often used for industrial and commercial purposes. You can find #6 through #8 rebar used in heavy-duty applications such as retaining walls, high-rise buildings, and parking garages. 

Rebar prices by type

Steel is the most common material used to make rebar, but rebar can also be made from other types of metal. The type of rebar you’ll need when inputting information into a rebar calculator could depend on the installation location and application, so it’s best to consult a professional contractor to determine which one will be required.

  • Steel rebar is weldable and made of basic, untreated steel. This rebar material costs between

    $0.18 and $6.80 per linear square foot

    .

  • Stainless steel rebar resists corrosion and is maintenance-free, so it costs more than standard steel. Plan to pay between

    $2.50 and $16 per linear foot

    for this material.

  • Galvanized rebar features a zinc coating that helps resist excess corrosion over time. The price for this rebar varies between 10-15% more than untreated steel.

  • Known as black rebar, epoxy-coated rebar is approximately 10 cents more per pound than uncoated steel and comes in between

    $300 to $400 per 50-pound box

    .

  • Fiberglass or Glass Fiber Reinforced Polymer Rebar (GFRP) are fiberglass rods with a lightweight feel. This option is a good alternative to steel as it’s corrosion-resistant and has exceptional tensile strength. GFRP rebar prices vary based on location and the supplier your contractor uses. 

Additional rebar cost factors

Your contractor may need to use rebar stirrups — parts that hold the sections of the rebar together. Each rebar stirrup may cost $5 to $20 or higher, depending on the size. These stirrups are either square or rectangular and are between 6 to 36 inches or larger — depending on the application.

When purchased in bulk, rebar is typically priced by ton. Plan to spend from $850 to $2,500 per ton of bulk rebar. Importantly, you likely won’t need to buy this material in bulk for most standard residential applications. Typically, only large wholesalers or contractors purchase rebar this way.

Depending on where you live, you could pay more for rebar. For example, if you live in a rural area where less stock is available or demand is high, your price per linear foot will likely be higher.

The cost of rebar also depends on the current steel market rate. The price of steel per pound fluctuates depending on market conditions. The price will also go up if there are any supply chain issues at the time of your order.

Based on the grades mentioned above, your rebar cost will also vary depending on which option you need. Generally, the higher the rebar grade, it will cost more than lower grade options. The price will also depend on the size, which includes both the rebar's length and diameter.

DIY or hire a pro

Installing rebar requires skill and a thorough understanding of concrete and the specialty tools required to cut, bend, and tie the rebar. You’ll also need to be able to read and understand engineering or architectural construction plans. If not installed correctly, rebar can be a safety risk that may cause the concrete to sag, crack, or even collapse over time. While you may want to try installing rebar yourself to save some money, this home project is best left for professionals to handle. Look for a local concrete installation company or a concrete floor installer to ensure the rebar job is done right.

Product Information

Reinforcing Steel

Tower foundation designs are relatively easy for the reinforcement steel fabricator to provide a quick quotation for your proposals. For budgetary considerations, you can use the pricing structure below for pricing by the linear foot or per pound  based upon the foundation design drawings. Smaller projects have been averaging $0.65 to $0.70 per pound. A larger foundation can range between $0.45 and $0.52 per pound. These national averages are for ASTM A-615 Grade 60,  deformed reinforcement bars with a 10% lap allowance, cutting and bending as well as shop drawings and delivery to the  jobsite with identify tags per the shop drawings. Add to your material pricing, taxes, chairs, mortar blocks, splicing, spiral caissons, if required. From October of 2003 to 2004, rebar pricing increased 43%. On large projects it is important to get a quotation from your supplier. Many mills are applying surcharges and you may not know what the steel from your fabricator is going to cost you when the project is let. For the past 30 years, reinforcing steel prices have been very steady, keeping in a plus or minus 10% bandwidth. There have been tremendous increases during 2003 and 2004.

Electrically welded steel wire mesh for slab foundations is also priced below with 15% waste and overlap included.

All detailing, fabrication and placing of the reinforcing steels should  conform to the manual of standard practice, ACI 315. If you have trouble remembering how big in diameter a #6 rebar is, multiply 6x1/8" which equals 3/4". Using the same 1/8" calculation, a #4 will be 1/2", etc.

We recommend that you contact our valued reinforcement steel manufacturers and distributors for your site-specific rebar requirements.
