What is the GB tolerance of I-beam?
The allowable deviation of + 0.06t 1, the average thickness of steel legs.2. The bending deflection of I-beam should not exceed 0.15d.The outer edge of the slope 3, I-beam legs, one leg is not greater than 1.5%b, not more than 2.5% legs.4, steel legs, shoulder passivation shall not be equal to 0.18T diameter of the round bar through.
Shape:1, bending degree. The camber of I-beam is not greater than 2mm. per meter, and the total bending is not greater than 0.2% of the total length.2, twist. I-beam shall not be subject to obvious torsion.
