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

#3 rebar is commonly used in concrete construction for various purposes where moderate reinforcement is required. Some typical uses include:

1. Concrete Slabs: Used as reinforcement in concrete slabs for residential and light commercial applications such as driveways, sidewalks, and patios.
2. Footings: Employed in footings to provide structural support and stability for buildings, retaining walls, and other structures.
3. Garden and Landscape Projects: Utilized in garden beds, retaining walls, and other landscape features to enhance strength and durability.
4. Paving: Used in reinforced concrete paving projects, such as small roads, pathways, and pavements.
5. Decorative Concrete: Incorporated into decorative concrete elements such as stamped concrete, where reinforcement is necessary to prevent cracking and ensure longevity.

Overall, #3 rebar is suitable for light to moderate load-bearing applications where additional strength and stability are required in concrete structures.

Rebar, short for reinforcing bar, is used in concrete construction to enhance the tensile strength of the concrete. The size of rebar is commonly designated by a number, which corresponds to its nominal diameter in eighths of an inch in the United States.

A #3 rebar (rebar size 3) has the following specifications:

• Diameter: 3/8 inch (or 0.375 inches)
• Metric Equivalent Diameter: 9.525 mm

The number "3" in #3 rebar means it is 3/8 inch in diameter (3 divided by 8 equals 0.375). This sizing convention helps in identifying the rebar size quickly based on its number designation.

To determine the weight of #3 rebar per foot, you can refer to standard industry weights for rebar sizes:

• Diameter: 3/8 inch (0.375 inches)
• Weight: 0.376 pounds per foot, or 0.561 kilograms per meter

This means that if you have a length of #3 rebar, you can calculate its weight by multiplying the length in feet by 0.376 pounds per foot.

An Example

For a 10-foot length of #3 rebar:

Weight = 10 feet × 0.376 pounds per foot = 3.76 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.

In short: you would get approximately 266 pieces of 20-foot #3 rebar in a ton.

To determine how many you get in a ton, you need to know the weight of one. Here is a step-by-step process to make this calculation:

1. Determine the Weight: #3 rebar has a diameter of 3.8 inch (0.375 inches). The weight per linear foot is typically 0.376 pounds.
2. Calculate the Number of Linear Feet in a Ton: 2000 pounds / 0.376 pounds per foot ≈ 5,319.15 feet‍
3. Determine the Length of Each Rebar: If you need the number of individual rebar pieces, you need to know the length of each piece.

For example, if each rebar is 20 feet long:‍

1. Calculate the Number of Rebar Pieces in a Ton: Linear Feet per Ton / Length of Each Rebar (in feet)

For a 20-foot rebar:

5,319.15 feet / 20 feet ≈ 265.96 rebars

So, in a ton of #3 rebar, you would get approximately 266 pieces at 20 feet each.
