Measure the length and width, in inches, of the rectangular steel sheet. For example, the length might be 135 inches while the width is 50 inches. Multiply the length by the width to obtain the area of the steel in square inches.Mar 13, 2018
How do I calculate how much rebar I need?
For example, if your footings are 140 total feet long and your footings are 24 inches wide, then multiply 140 feet times three. You will get 420 feet. This is how much vertical rebar you will need for your 24-inch footers. Because rebar comes in 20-foot pieces, divide 420 by 20 and you get 21 sticks of rebar.

What does rebar size mean?
Ever wonder what the size number for rebar represents? ... The number represents a unit of 1/8 of an inch. So that means a #4 rebar is 4 times 1/8" or in other words - 1/2". #5 bar is 5/8"; #6 bar is 3/4" and so on. To cut and bend your rebar, check out the rebar cutters and rebar benders at Fascut Industries.Dec 12, 2017
How do you measure rebar size?
Rebar is sized nominally by "eighths of an inch" of the bar's diameter. Every bar can be measured in eighths of an inch. A #3 bar is 3/8" in diameter. A #6 bar is 3/4" in diameter.
What are common rebar sizes?
A. The most common sizes of rebar are #4 and #5 rebar which is used in residential and light commercial construction, as well as, commercial construction.
How is rebar sized and specified?
US sizes. US/Imperial bar sizes give the diameter in units of 1⁄8 inch (3.2 mm) for bar sizes #2 through #8, so that #8 = 8⁄8 inch = 1-inch (25 mm) diameter. The cross-sectional area, as given by πr², works out to (bar size/9.027)², which is approximated as (bar size/9)² square inches.
What is the area of reinforcement?
Generally the effective tension area should be taken as having a depth equal to 2.5 times the distance from the tension face of the concrete to the centroid of the reinforcement. although for slabs the depth of this effective area should be limited to [li — x)/3. An overall upper depth limit of h/2 also applies.May 30, 2021

What is the area of steel?
Rectangular Steel Surface Multiply the length by the width to obtain the area of the steel in square inches. Now, for the example, you have 135 inches times 50 inches, or an area of 6,750 square inches. Divide the area by 144 to change to square feet, since 144 square inches equals one square foot.Mar 13, 2018
How do you calculate the volume of a steel bar?
Find the volume of steel bar. If it is a circular steel bar, the volume is 22/7 x d^2/4 x L where L is the length of any bar in cm and dia also in cm will give you volume in Cu.,cm. Multiply the volume by specific gravity the weight of bar is evaluated in gram.
