Number 4 rebar, a common reinforcement bar used in construction, has a diameter of 5/8 inch (approximately 15.88 millimeters). Understanding rebar sizing is crucial for any construction project, ensuring structural integrity and compliance with building codes. This guide will delve into the specifics of #4 rebar and address some frequently asked questions.
What is the diameter of #4 rebar in millimeters?
As mentioned above, #4 rebar has a diameter of approximately 15.88 millimeters. While the nominal diameter is often rounded, precision is important in construction calculations, so using the more accurate figure is recommended for precise measurements and material estimations.
What is the weight of #4 rebar per foot?
The weight of #4 rebar per foot is approximately 1.041 pounds. This weight is a crucial factor in calculating the overall weight of reinforcement steel needed for a project. Accurate weight calculations are vital for transportation, handling, and cost estimations.
How many #4 rebars are in a ton?
A ton (2000 pounds) of #4 rebar equates to approximately 1920 linear feet. This calculation allows contractors to determine the quantity of #4 rebar needed based on the project's requirements, optimizing material ordering and minimizing waste.
What is the area of #4 rebar?
The cross-sectional area of #4 rebar is approximately 0.20 square inches. This area is essential for structural calculations to determine the rebar's contribution to the overall strength of a concrete element.
What are the common uses of #4 rebar?
#4 rebar is versatile and commonly used in various applications, including:
- Residential Construction: Found in foundation walls, slabs, and other structural elements of houses and smaller buildings.
- Commercial Construction: Used in similar applications as residential projects, but on a larger scale, in supporting walls and slabs in larger commercial buildings.
- Highway and Bridge Construction: Employed in some aspects of these large-scale projects, though typically larger sizes are more common.
- Concrete Repair: Can be utilized in repairing damaged concrete structures.
Remember, while this information provides a good overview, always consult official building codes and engineering specifications relevant to your specific location and project. The accurate calculation and proper use of rebar are crucial for ensuring the safety and structural integrity of any construction project.
