ROUND BARS

CSA-G40.21 Gr.50W

CSA G40.21 grade 50W round bars are rolled or welded structural steel products. They are used in the construction of buildings, bridges, towers, cranes and other structures. Round bars are available in a variety of sizes and lengths to meet the needs your construction projects.

In the CSA (Canadian Standards Association / Association canadienne de normalisation) standard, measurements are expressed in SI (metric) units, with Anglo-Saxon (Imperial) values shown in brackets.

In metric (SI) units, this grade of steel is known as 350W.

In imperial units, we know it as 50W.

This is the same steel in two different units of measurement for the same CSA standard.

The minimum tensile strength for CSA G40.21 grade 50W round bar is 485 MPa (70 Ksi).
The minimum yield strength for CSA G40.21 grade 50W round bar is 345 MPa (50 Ksi).
CSA G40.21 grade 50W round bars have a minimum elongation of 21%.
Grade 50W contains carbon, manganese, phosphorus, sulfur, silicon, copper and nickel.
CSA G40.21 grade 50W round bars are easily welded using standard processes such as electric arc welding.

ASTM F1554 Grade 55

ASTM F1554 Grade 55 round bars are frequently used in the design of steel anchor rods for structural supports and concrete foundations.

ASTM (American Society for Testing and Materials) F1554 encompasses three grades for anchor rods:

36 (248 MPa / 36 Ksi)
55 (380 MPa / 55 Ksi)
105 (724 MPa / 105 Ksi)

ASTM F1554 anchor rods can take the form of headed bolts, straight rods or angled anchor bolts.

The minimum tensile strength for ASTM F1554 Grade 55 round bars is 380 MPa (55 Ksi).
The minimum yield strength for ASTM F1554 Grade 55 round bars is 205 MPa (30 Ksi).
ASTM F1554 Grade 55 round bars have a minimum elongation of 21%.
ASTM F1554 Grade 55 round bars contain carbon, manganese, phosphorus, sulphur, silicon and copper.
