M = round mild steel, H = round area high yield, S = square area high yield. BS 4466:1969. R = round mild steel, Y = round area high yield.
What do the letters on rebar mean?
A range of individual markings reveal the identification of each individual rebar: The first letter or symbol means producing mill and deformation pattern. The second marking means the bar size, in this picture, ” 11 ” means the diameter of this rebar is #3.
What does T stand for in rebar?
The main reason this mark is to identify the tensile test piece method. Because of the tensile test piece of the heat treatment deformed bars shall be the full section of the bar as rolled (not finished mechanically) follow last line in clause 9.5.2.21. So the “T” symbol is represented the production process only.
What does T & B mean in rebar?

What is 10M rebar?
What size is 10m rebar:- metric bar size designation represents the nominal bar diameter in millimetres, rounded to the nearest 5, nominal diameter of 10M rebar is 11.3mm, it is rounded to 10mm, size/ diameter of 10M rebar is equal to their nominal diameter in mm, so size/ diameter of 10M rebar is 11.3 in mm or 0.45
Is rebar hard to forge?
A first major con of using rebar for blacksmithing is its unpredictable nature. Most rebar is not made of quality metals and can even contain dangerous fumes when worked. You can never be sure what the rebar is made of, so final projects can end up brittle.
What is y12 steel bar?
A common steel bar that is usually formed from carbon steel, and is given ridges for better mechanical anchoring reinforced concrete.
How many pieces of rebar are in a ton?
To determine how many pieces of 60 ft length of 5 rebar size in a ton, weight 60ft long is around 62.58lb, 1 ton is equal to 2000lb, number of pieces = 2000/ 62.58 = 32, so there are 32 pieces of 60 ft length of #5 or 16mm rebar in a ton.

What is the difference between T Bar and Y Bar?
“T” bars are structural bars used in building as are “H” and “L” shaped bars plus many other shapes. The main problem with “Y” bars for building is that you cannot bolt it in place due to the shape. All the “Y” bars I have seen are steel while “T” shapes can come in steel, galvanized steel and Aluminium.
What are the grades of reinforcing steel?
Product Guide
| Rebar Grade PNS 49:2020 | Rebar Grade Mark | Ductility Class (Mark) |
|---|---|---|
| Grade 280 | 3 | Regular (R) or Weldable (W) |
| Grade 420 | 4 | Regular (R) or Weldable (W) |
| Grade 520 | 5 | Regular (R) |
| Grade 550 | 6 | Regular (R) or Weldable (W) |
What are the grades of rebar?
Common grades are 40, 60, 75, 80, and 100. The nomenclature for the grades represents how much yield the rebar has. For example, grade 40 rebar has a minimum yield strength of 40 KSI, which is equal to 40,000 PSI, whereas grade 80 rebar has a minimum yield strength of 80 KSI or 80,000 PSI.
How can you tell a 706 rebar?
Bar Markings
- The first letter or symbol identifies the producing mill.
- The next marking is the bar size.
- The third marking symbol designates the type of reinforcing steel — usually either “S” for carbon-steel (ASTM A615) or “W” for low-alloy steel (ASTM A706).
What do the numbers and letters mean on rebar?
It’s actually quite easy. 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.
What does EF mean in rebar?
Structural Abbreviations
| ASD | Allowable Stress Design |
|---|---|
| EF | Each Face |
| EJ | Expansion Joint |
| ES | Each Side |
| EQ | Equal |
How do you know the grade of rebar?
One of the easiest is to look for the stamped numbers and letters between the lines on the rebar. This may include a set of three characters, such as B6S. This means that the manufacturer is shown by the letter B, it’s grade 60 rebar and it’s made of steel. If there’s another number there, that may show rebar sizes.
