  • The uses and classification of corrugated steel plates

    Corrugated steel plate is a steel plate with a corrugated surface made of stamped thin steel plates. Corrugated steel plates are made from cold-rolled or hot-rolled steel plates that have been formed multiple times, so they have high bending and tensile strength. Corrugated steel panels are widel...
