How do you find the DIA of a steel bar?
Hence, the weight of :
- 10mm dia bar = (10x10x1)/162.28 = 0.616kg.
- 12mm dia bar = (12x12x1)/162.28 = 0.8874kg.
How do you measure a steel bar?
Rebar Size Chart
Each imperial bar diameter increases by 1/8 inch. You can multiply the bar size by 1/8 to get the nominal diameter in inches. For example, #8 rebar = 8/8 inches (or 1 inch) in diameter. Common measurements indicate the weight, nominal area, and nominal diameter.
How do you measure the diameter of a steel rod?
Measure the length (L, in cm)of the rod and use the formula, V = (pi)r^2*L. Find out r (radius in cm) and double it to get the diameter, cm.
What is a bar 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. 3/4 is the same as 6/8. A #10 bar is about 10/8″ in diameter.
What instrument is needed to check the size of a steel bar?
Gauges are usually regarded as either fixed-type or deviation-type instruments. Fixed-type gauges are used to indicate whether a given dimension is larger or smaller than the standard. They may be of hard steel, soft steel, or glass.
How do you measure bar spacing?
Minimum spacing between two bars can be taken as approximately 50–75 mm. According to cl. 26.5. 1.5 of IS 456, the maximum spacing of the stirrups = 0.75 d = 0.75 (450) = 337.5 mm = 300 mm (say).
How do you calculate the spacing of steel bars in a slab?
The minimum and maximum spacing reinforcement in concrete structural members such as beams and slabs are required as per standard codes.
1. Minimum Spacing between Bars in Tension
- 15 mm,
- Two-third of the nominal size of coarse aggregate, or.
- Maximum size of the bar or whichever is greater.
What is nominal diameter of steel bars?
Nominal diameter may be defined as the dimension of the diameter (in mm) of round bar. In case of deformed bars, the nominal diameter is taken equivalent of that of a plain bar having the same mass per unit length as the deformed bar.
How do you measure the diameter of a reinforcement bar?
Rebar sizes
For the imperial-unit countries, bar sizes give the diameter in units of the ⅛ inch for bar sizes #2 through #8. For example, 8⁄8 = #8 = 1 inch diameter. Equivalent metric size is typically specified as the nominal diameter rounded to the nearest millimeter.

What is the size of a steel bar?
TMT steel bars come in different diameters like 8mm, 10mm, 12mm, 16mm, 20mm, 25mm, 32mm, 36mm and now some well-known TMT manufacturing companies are planning to manufacture in larger diameters. 8mm-10mm size bars are used in Slabs and Stair ups, which serves as a load bearing member in slab homes.
How many diameters does a rod have?
Generally, the length of a standard TMT bar is 12 metres; it is the diameter that varies. The diameter can be 8 mm, 10 mm, 12 mm, 16 mm, 20 mm, 25 mm or 32 mm.
What is the best instrument for measuring diameter of a metal rod?
Question: The diameter of a metal rod is measured by 12 inspectors, each using both a micrometer caliper and a vernier caliper.
What tool is used to measure the diameter of the bar for better measurement?
A caliper (British spelling also calliper, or in plurale tantum sense a pair of calipers) is a device used to measure the dimensions of an object. Many types of calipers permit reading out a measurement on a ruled scale, a dial, or a digital display.
What is the diameter of #7 rebar?

- Mechanical Instrument.
What do you use to measure the thickness of an iron rod?
Use a Caliper
The most precise way to measure a metal’s thickness is to use a caliper. Calipers are hand tools designed to precisely measure the distance between two points. Just fit the two tips of the caliper around the metal you need to measure to determine its thickness.
What will be the spacing at middle for tie bar for beam?
Construction of Beams
of vertical stirrups should be 8 mm diameter. The spacing should be 100 mm c/c at 1/3 span of beam at supports and 150 mm c/c at remaining mid span of beam.
