#7 Rebar — Size, Weight, Use-Cases and More

#7 rebar is commonly used in concrete construction for various applications where strong reinforcement is necessary. 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, #7 rebar is suitable for a wide range of construction projects requiring strong reinforcement in concrete structures subjected to heavy loads and structural demands.

A #7 rebar (rebar size 7) has the following specifications:

• Diameter: 7/8 inch (or 0.875 inches)
• Metric Equivalent Diameter: 22.225 mm

The number "7" in #7 rebar indicates that it is 7/8 inch in diameter. This sizing convention is used to easily identify the rebar size based on its number designation.

To determine the weight of #7 rebar per foot, you can refer to standard industry weights for rebar sizes:

• Diameter: 7/8 inch (0.875 inches)
• Weight: 2.044 pounds per foot, or 3.049 kilograms per meter

This means that if you have a length of #7 rebar, you can calculate its weight by multiplying the length in feet by 2.044 pounds per foot.

An Example

For a 10-foot length of #7 rebar:

Weight = 10 feet × 2.044 pounds per foot = 20.44 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.
