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.
3.4 The bending of the length of the cathode flat bar shall comply with the requirements of Table 3.
Table 3 Curvature mm
Degree of roughness
3.5 The four corners along the length of flat steel, the arc radius 5mm ~ 15mm.
3.6 After consultation between the supplier and the buyer, special specifications and requirements are ordered according to the agreement between the supplier and the buyer.
Cathode flat steel is delivered according to actual weight. After negotiations between supply and demand sides, they can also be delivered according to theoretical weight. Flat steel measurements are calculated according to nominal dimensions and the specific gravity is calculated at 7.85t/m3.
