CORRUGATED SHEET PROFILE Russian patent published in 2004 - IPC

Abstract RU 2238815 C1

FIELD: manufacture of rolled products, may be used in mechanical engineering for manufacture of corrugated sheet profiles.

SUBSTANCE: corrugated sheet profile has predetermined number of through longitudinal and transverse corrugations separated by flat portions. Profile has thickness S=0.8-2.0 mm. Longitudinal corrugations are made triangular, with predetermined apex angle, and have height and bending radius. Transverse corrugations have arced cross section. Radius defining corrugation apex exceeds radius of corrugation base. Height of transverse corrugations exceeds height of longitudinal corrugations.

EFFECT: increased transverse rigidity of profile without deteriorating quality thereof, and reduced metal wear during operation of profile.
