Note 1: These sizes are only produced to Grade 500

Tolerances on Kg/m

≥ 3 mm diameter& ≤ 6 mm diameter + / - 9.0% kg/m
≥ 7 mm diameter & ≤ 12 mm diameter + / - 6.0% kg/m
> 12 mm diameter + / - 4.5% kg/m

Tolerance on Bar Length

Unless otherwise specified: +100 / -0 mm on nominal length

Tensile Strength

Three Grades in British Standard:

  • Grade 200 ²
  • Grade 500
  • Grade 650

Note 2: to be specified for plain bar only

Grade of tensile strength based on the following measures:

  • 0.2% proof strength (R p0.2) in MPa or N/mm2
  • stress ratio: Rm/R p0.2 (min.)
  • elongation at fracture: A5 (min.)
  • total elongation at maximum force, Agt (min.)
