The following definitions apply to this standard.

2 brand representation

Flat steel grades are indicated by steel grades and cross-section dimensions, such as Q215-120×198. Q195 - carbon structural steel grade, 120 × 198 - the sectional size of the cathode flat steel.

3 Size, shape, weight and allowable deviation

3.1 The flat steel thickness and its allowable deviation shall comply with the requirements of Table 1.

  Table 1 Thickness tolerance     mm












3.2 The width of the flat steel and its allowable deviation shall comply with the provisions of Table 2.

      Table 2 width tolerance      mm












3.3 Flat steel length and its allowable deviation

The cathode flat steel is delivered according to a fixed length, the length of the fixed length shall be specified in the contract, and its allowable length deviation is 0 to +15 mm.
