What is 11 rebar used for?

#11 rebar is commonly used in concrete construction for various applications where heavy reinforcement is needed. Some typical uses include:

  1. Structural Beams and Columns: Utilized to reinforce structural beams, columns, and other load-bearing elements in buildings, bridges, and other structures to enhance strength and resist bending.
  2. Foundation Slabs: Employed in the construction of foundation slabs for residential, commercial, and industrial buildings to provide structural support and stability.
  3. Retaining Walls: Utilized in the construction of retaining walls to strengthen the structure and prevent soil erosion or collapse, especially in larger and taller walls.
  4. Parking Structures: Used in the construction of parking garages and parking lots to reinforce concrete floors, ramps, and decks subjected to heavy vehicle loads.
  5. Bridge Decks: Incorporated into bridge decks and highway structures to reinforce the concrete and ensure durability and longevity under heavy traffic loads.
  6. Water and Wastewater Structures: Employed in the construction of water treatment plants, wastewater treatment facilities, and storage tanks to provide reinforcement in concrete structures subjected to environmental conditions and water pressure.
  7. High-Rise Buildings: Used in the construction of high-rise buildings to reinforce concrete elements such as shear walls, cores, and slabs to withstand vertical and lateral loads.

Overall, #11 rebar is suitable for a wide range of construction projects requiring heavy reinforcement in concrete structures subjected to significant loads and structural demands.

Size & Diameter

What size is 11 rebar?

A #11 rebar (rebar size 11) has the following specifications:

  • Diameter: 1.41 inches
  • Metric Equivalent Diameter: 35.81 mm

The number "11" in #11 rebar indicates that it is 11/8 inches in diameter, which simplifies to approximately 1.375 inches, although the actual diameter is slightly larger. This sizing convention helps in identifying the rebar size based on its number designation.

Weight Per Foot

11 rebar weight per foot

To determine the weight of #11 rebar per foot, you can refer to standard industry weights for rebar sizes:

  • Diameter: 11/8 inch (1.41 inches)
  • Weight: 5.313 pounds per foot, or 7.924 kilograms per meter

This means that if you have a length of #11 rebar, you can calculate its weight by multiplying the length in feet by 5.313 pounds per foot.

An Example

For a 10-foot length of #11 rebar:

Weight = 10 feet × 5.313 pounds per foot = 53.13 pounds

This weight calculation is helpful for estimating the total weight of rebar needed for a project or for making sure you’re compliant with structural design specifications.
