Ironwood sidewalls are naturally rot resistant providing water resistance and, unlike UHMW and ABS, bond great. No additional treatment (i.e. flame treatment) is needed to bond. Works well with wood glues and epoxies. Our preference is thick wood glues. These sidewall strips are .5" thick and .45" wide. Ironwood has a high modulus, adding to the torsional stiffness of your ski or board. Available by the piece or bulk.
