Steel Rebar Sizes & Stock
When managing large-scale commercial construction or heavy infrastructure builds, securing the right materials on time is critical. We maintain a massive inventory of concrete reinforcing bar to keep your projects moving without delay. We stock Grade 40 and Grade 60 materials to meet standard yield strength demands, along with weldable A706 options. These products are available in standard lengths of 20 and 30 feet, as well as extended 40 and 60-foot cuts. Explore our complete selection of standard sizes below to find the exact dimensions required for your structural engineering needs.
High-Volume Concrete Reinforcement Supply
As a premier distributor backed by Nucor, we have the logistical capabilities to fulfill massive truckload orders across the country. We do not cater to consumer retail projects; our focus is entirely on supplying major job sites and fabrication yards with consistent material. Our inventory includes a wide range of grades and finishes to suit specific environmental requirements. We supply standard black rebar along with epoxy coated rebar for highly corrosive marine environments. We also provide coiled and spooled rebar to maximize manufacturing efficiency for automated fabrication shops.

Choosing Rebar Sizes by Construction Project
Selecting the appropriate diameter is essential for maintaining the structural integrity of your concrete pours. We stock a comprehensive range of dimensions to support everything from light masonry to heavy civil engineering.
Small Diameter Rebar (#3 to #5)
Sizes 3 through 5 are highly flexible and easy to shape. These lighter bars are commonly used to reinforce swimming pools and residential foundations. They also provide excellent crack control for concrete driveways and light commercial slabs.
Medium Diameter Rebar (#6 to #9)
Sizes 6 through 9 provide significantly more tensile strength for load-bearing structures. Contractors frequently rely on these medium dimensions when building retaining walls and commercial parking structures. They are also standard requirements for tilt-up concrete panels and heavy masonry work.
Large Diameter Rebar (#10 to #18)
Sizes 10 through 18 are engineered for massive commercial structures and high-stress environments. These heavy-duty bars are required for bridge construction and parking garage support columns. Engineers also specify these massive diameters for deep foundation caissons and high-rise commercial buildings.
