FLAT BARS

CSA-G40.21 Gr.50W

CSA G40.21 grade 50W flat 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 of construction projects.

These bars are generally used to make square tie plates as a component of anchor rods cast in concrete.

In the CSA (Canadian Standards Association / Association canadienne de normalisation) standard, measurements are given 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 flat bar CSA G40.21 grade 50W is 485 MPa (70 Ksi).
The minimum yield strength for flat bar CSA G40.21 grade 50W is 345 MPa. (50 Ksi)
CSA G40.21 grade 50W flat bars have a minimum elongation of 21%.
Grade 50W contains carbon, manganese, phosphorus, sulfur, silicon, copper and nickel.
CSA G40.21 grade 50W flat bars are easily welded using standard processes such as electric arc welding.

ASTM A36

ASTM A36 flat bars are rolled or welded structural steel products. They are used in the construction of buildings, bridges, towers, cranes and other structures. Flat bars are available in a variety of thicknesses and widths to meet the needs of construction projects.

These bars are generally used to make square plates as a component of anchor rods cast in concrete.

The minimum tensile strength for ASTM A36 flat bars is 400 MPa (58 Ksi).
The minimum yield strength for ASTM A36 flat bars is 250 MPa (36 Ksi).
ASTM A36 flat bars have a minimum elongation of 20%.
ASTM A36 flat bars contain carbon, manganese, phosphorus, sulfur, silicon and copper.
ASTM A36 flat bars are easily welded using standard processes such as electric arc welding.
