Metal roof plate for increasing transverse bending rigidity and anti-skid friction force
The invention relates to a metal roof plate for increasing transverse bending rigidity and anti-skid friction force. The metal roof plate is characterized in that rectangular, round-ended or circular transverse ribs are arranged between a left rib and a right rib of the roof panel through impact molding, so the transverse bending rigidity and the anti-skid friction force of the metal roof plate are increased. Under the condition that the thickness of the metal roof plate is not increased, the transverse bending rigidity of a cross section is increased through the transverse ribs formed through impact molding, the rigidity of the cross section with a wind uplift effect is enhanced, and the capability of resisting against quick slippage of accumulated snow is increased. Meanwhile, smooth flow-down of rainwater is not obstructed by the discontinuous transverse ribs, so the problem of ponding is not caused.
