Structure Type

colored corflute sheet
wide rib fluted sheet

Wide ribs allow the corflute sheet to have a lower weight, stronger and harder surface, and the larger hollow allows the support rod to be inserted.

narrow pp fluted sheet

Narrow ribs make the thin corflute sheet lighter, stronger and easier to produce. 

S-lines pp fluted sheet

The core ribs of the corflute sheet are S-lines. S corflute sheet is much more strong than those sheets with narrow or wide ribs sheet. 

flat pp fluted sheet for printing

Polyreflex printing-grade corflute sheet has very flat surface and is suitable for printing signs.
