Note 1.According to the requirments of demanding party,the company can produce5 multiples of the rolled material(the norminal diameter of more than 40mm,allowable deviation of the weight:±4%) | |||
2.Allowable deviations of the weight are quoted for the some steel bar | |||
3. Steel bar weight per meter is determined by the nominal diameter, the density of steel 7.8kg/cm2 |
