Most house walls use ** 1/2- or 5/8-inch ** rebar, but shorter walls and those that are not load-bearing sometimes are built with 3/8-inch; the smaller size is most often used in horizontal applications to match mortar joints. Rebar may be smooth or have ribs to better fasten in mortar; ribbed is most common in home building.

The total cost for installing rebar is ** $1-$1.20 ** per square foot. This will translate to $500-$600 for a 500 square foot area. The labor for a 500 square foot is averaged at $280-$345. This is equivalent to roughly $62-$76.50 per hour. Other than labor there are materials and supplies that are needed to install rebar reinforcements.

## What size rebar should I use?

A commonly used rebar chart is given below: Bar Size Designation ** Weight (lb/ft) Bar Diameter ** (in) Bar Diameter (mm) Cross-Sectional Area (in2)

#3 0.376 0.375 9.525 0.11

#4 0.668 0.5 12.7 0.2

#5 1.043 0.625 15.875 0.31

#6 1.502 0.75 19.05 0.44

Another popular inquiry is “What size rebar should you use for a concrete slab?”.

One answer is that The choice between rebar or wire mesh often depends on the strength desired in the end product. Some contractors prefer to use both in their concrete slabs – rebar between the ** 1/2 ** and upper 1/3rd and mesh between the upper 1/3rd and 1/4 of a 4” thick pad.

How do I choose the best rebar sizes?

There are various factors to be tested that fall into the following categories: ** Tensile strength, bending/malleability, compression, and fatigue. **

Here is what our research found. The mills will generally not supply anything longer than ** 60 ft ** (the standard length) since it cannot be handled using normal means. Lengths greater than this should be lapped or coupled. If you require longer lengths of #8 or larger bars, and cannot lap splice or couple, plan on using welds per AWS D1.4 on ASTM A706 rebar.

## How to calculate amount of rebar?

Calculate Rebar Quantity From ** Total Slab Area and Perimeter ** To calculate Total Area of a multi sided slab, first divide the shape into rectangles or squares. (as in example diagram) Multiply the 2 different side lengths of each rectangle to find individual areas, then add them together to find Total Slab Area.

How do you calculate rebar?

Find out the total length of rebar. ** Multiply that length of rebar by the weight per length ** associated with the size of rebar that is used. To figure out the total length of rebar in a grid used in a slab, there are several factors: The dimensions of the slab (length, width and depth) The spacing of the rebar. The inset from the edge of the slab before the rebar is used.

You may be thinking “How do I estimate the quantity of rebar in slab?”

The most frequent answer is, convert your longitude measurement into inches: 15 feet x 12 inches per foot = 180 inches. Divide your result by the spacing measurement: 180 in / 14 in = 12.87 (round up to 13)Add one rebar to your result: ** 13 + 1 = 14. **
