Description
Deformed Bar Traders Standards are Identified by the Following:
- The letter or symbol of the producer’s mill will be rolled into the rebar.
- The size of the bar is rolled into the rebar and appears as a numeral.
- The symbol for the type of STEEL PIPE Traders (These are limited to S – carbon steel, I – rail steel, A – axle steel, W – low alloy steel, IR – rail meeting, SS – stainless steel, CS – low carbon chromium)
- The grade of the rebar will be signified (40, 60, 75, 80, 100 or 120), or the addition of one, two, three or four lines that must be five deformations long will appear
Clearly, the markings do more than tag the deformations. In fact, each marking system provides details about the traders and composition of each bar of reinforcing steel. The standards and grades available include ASTM International sizes and standards which are Imperial sizes, but there are metric equivalents too. EN 10080 metric designations are also available in addition to Canadian grades and sizes.
American builders and buyers will use the following grades and sizes
Bar # | Diameter in inches | Metric # |
3 | 0.375 | 10 |
4 | 0.5 | 13 |
5 | 0.625 | 16 |
6 | 0.75 | 19 |
7 | 0.875 | 22 |
8 | 1 | 25 |
9 | 1.128 | 29 |
10 | 1.27 | 32 |
11 | 1.41 | 36 |
14 | 1.693 | 43 |
18 | 2.257 | 57 |
There are also three grades of Imperial size that have metric equivalents:
Inch grade | Metric grade | Pounds per square inch | Megapascals |
40 | 280 | 40,000 | 280 |
60 | 420 | 60,000 | 420 |
75 | 520 | 75,000 | 520 |
There are many rules and guidelines for using various grades, and the following are applicable ASTM Standards by Grade:
40 & 50 | 60 | 75 | 300 & 350 | 420 | 520 | ||
S | billet | A615 | A615 | A615 | A615M | A615M | A615M |
I | rail | A616 | A616 | — | A996M | A996M | — |
IR | Rail Meeting Supplementary Requirements S1 | A616 | A616 | — | — | — | — |
A | axle | A617 | A617 | — | A996M | A996M | — |
W | Low-alloy | — | A706 | — | — | A706M | — |
European builders and buyers will use EN10800 metric designations. These appear as a K followed by the mass of the bar in kilograms, per one meter of length. For instance, K3 weighs three kilograms per meter.
Canadian Rebar Supplier identify with a symbol for the mill followed size of the bar. This will feature numerals and then the grade symbol.
Historically, the use of ferrous steel introduced to eliminate the risks of corrosion. Though it is possible to find other metals or grades, it is steel Rebar traders. All standard sizes & grades are in stock. We produced in top quality mills for European Union and Asia.
